Shimano’s Crank Disaster & Is This The Next Big Cycling Trend? - The Wild Ones Podcast Ep.17

[@carstens8919]

I just love this! Podcasts often suffer when the 'main cast' is missing but I think Nic is a good guest, mainly in this topic. And also great to see Emily again. Great Job Boys and Girls.

[@123moof]

Emily is a great addition, hopefully she can be included more often.

[@soverania8041]

Can't wait for a set of mudguards re-designed by big bike manufacturers that are: - made of carbon fiber - marketed as "lightest" and "most aero" - proprietary and only fits one bike model - has internal cable routing (for ebike lights?) - starts to creak after a few hundred miles

[@BrotherMichigan]

Actual (astro)physicist here: the thing with vibration and energy lost *is* directly tied to rolling resistance. "Absorbing vibration" with larger tires lets you go faster because you're not putting a bunch of energy into lifting the whole bike and rider up over the little bumps as the tire rolls. Jimmi's comment about "spongy" components costing you watts is absolutely true, it just happens that the energy required to deform a larger tire (or tire run at lower pressure) is less than the energy to required to lift the bike/rider system over the tiny height of the bumps in the road. That same advantage doesn't translate to something like a Redshift stem or Futureshock because those are supporting much less weight overall than the tires, so it's not really correctly to say that adding comfort elsewhere is going to make you faster in the same way that bigger/softer tires will. There probably IS something to be said about a more comfortable bike making you faster in the long run, but that's just because it won't beat you up as much and you'll feel fresher later into longer rides than if you're on an unforgivingly stiff race bike for 6-8 hours straight.

[@jwfriar]

I was running 28s, got a major puncture while on vacation that wouldn't seal. LBS mainly did MTB, but did have a tubeless Vittoria 32 that I was "forced" to use. Dear lord - the grip, the comfort have been amazing. I swear they are faster too. Win/Win/Win.

[@edboy_1]

Which is also why tire design and rubber compounds engineering mark such a big difference between a slow and a fast tire. The lesser the hysteretic losses of a compound (ie heat from rubber deformation) the more kinetic energy you are able to maintain, and when you run a lower tire pressure this starts to matter even more as the tire contact patch gets bigger (more room for rubber deformation, the main loss on a perfect road). Though, running lower pressures is a necessary evil when dealing with a less-than-perfect road surface, as each bump or cobble we roll over is like hitting a mini-wall which redirects a fraction of our energy in the opposite direction every time. We are basically just using the elastic and hysteretic deformation of our tires to "offset" and absorb the equal and opposite force that we would receive from the mini-wall (cobble or bump), so that the horizontal vector component acting against our direction of travel results as little as possible, and running lower tire pressures basically just raises the threshold for how big of a bump we can efficiently compensate for! Bottom line: choosing a low rolling resistance tire AND running it with adequate pressure for the surface is some serious compounding power gains

[@kornenator]

Nic is the ultimate guest appearance on my favourite cycling channels, always adding something extra

[@_Just_Some1]

Which other channels does he appear on? Thanks

[@andrewmcalister3462]

Kudos to Emily for having done her research and being the best prepared of the presenters (especially on the Shimano recall issue). And respect for Nick and the deep knowledge he brings.

[@rehview]

The problem with tubeless is that you only get negative feedback. When it goes wrong, you remember; when it works, you don’t realise.

[@FuriousFilipino]

The worst part is realizing that when it doesn’t work and you need to put a tube in, that you need a clamp to break the bead off the rim. As a former mechanic, I always advised all my clients to remove and replace their own tires to see if they can. There are some rim & tire combos that even the strongest hands simply can’t break from the bead-or at least have to sit on the side of the road and repeatedly try with improvised tools until it does.

[@jamesmckenzie3532]

We have a lot of debris here on and off the road. One thing you HAVE to do here is a thorough sweep of the tire unless you are absolutely certain of what caused the puncture. I swept a tire and we had to remove about a half a dozen thorns and glass pieces to clear the tire. Also, there are tools you can use to roll off/on tires. Get one and learn how to use it. Lastly,Silva is great, but you still have to top up and never use an injector to fill. You will destroy the injector. Lastly, work with the tire before mounting. Prestretching is a godsend. Warming the tire in the oven at 150F helps a lot. There are videos on tire mounting for tubeless.

[@holovka]

bank balance has been better since going away from tubeless. ROI vs a great tyre tube combo is worlds apart . tubeless is great WHEN it works and there’s too many variables that killed it for me.

[@_NoName...]

I can tell another problem: According to the info in the video, Silca all the way! And right now the SIlca Sealant is around 20€ per 236ml which equal 4 uses (actually and obviously, 2 uses as bikes have 2 wheels) Then, you need to top it up every 3 months. Meaning in 6 months you need to get another 236ml sealant bottle. Then, you need a specific valve, specific wheel, and specific tyre to start with the entire system. My classic inner + gp5000 didn't flat since 6500km last year. The only thing I have to do after installing them for the first time is pump them up regularly (which you have to do as well in the sealant-system). *why should I bother?*

[@tonyg3091]

There is no problem with tubeless, it just works

[@maxkehayov]

Nic is very well informed and grounded in the real life application of the bike tech discussed. His views and experience bring a lot of value to the table! Kudos guys and gal!

[@ChainringTattoo]

One thing people don't talk about with aerodynamics is a headwind. Few of us will ride at 40 kph for a long period of time. However, riding a pedestrian 20 KPH into a gentle 20 KPH breeze produces a 40 kph wind over your bars. Physics is everywhere.

[@uptown710]

US rider here. As my crank fell within the affected range, I took it in to one of the “official Shimano” dealers listed on their site. Oh man. First off, yes, my crank failed the inspection. Anyone who’s from NYC and has been to BH over in Chelsea, see Matt. Great guy. He told me after my crank was disassembled there was a noticeable/palpable line on my crank arm and also voids in the bonding material where to U shaped parts of the crank meet. Ok. Cool. Now the fun part begins. It turns out shimano will only accept cranks from those stores specific to what’s shown on their website. Which, AFAIK are only about 3 stores _in the entire NYC area_ not even the large bike brands (trek, specialized) are able to send them back to shimano. 2nd, shimano apparently has to verify the crank themselves before sending out a replacement. So even if your mechanic deems them faulty, the crank still has to be sent out physically to shimano for them to judge its condition. Therefore you’ll be without a crank until it’s sent back. They do not front the shop an allotment in the event of. What’s worse is if you’re on the east coat like me, it’ll take about a week for your crank to even arrive to shimano. And likewise on the way back. 2 weeks and I’m not sure how long shimano will take to “inspect”. I suggest if you have one of the cranks on the list you get the process started asap. The more new stuff I hear, the worse it seems.

[@markproulx1472]

I’m in the same boat. My dealer deemed my crank defective and sent it to Shimano. The Shimano gods also declared it defective and are sending me a replacement. What annoys me to no end is not that the defects exist, but that Shimano has addressed the problem in a supremely cumbersome way. All told, I’ll be without the bike for over a month. Not good.

[@uptown710]

@@markproulx1472oddly enough I got my bike back yesterday. It was ready to go after 9 business days. I can’t see that time improving as more people hear about this issue and more bikes show up at shops. I’m sorry to hear you may suffer from a long wait time. I lost damn near 2 weeks of training time because of this.

[@riggseroni]

This was a great episode! It's a good thing I live nowhere near Nic's shop, because if I did, I would buy absolutely everything he told me to get, no questions asked. Much respect for his knowledge and opinions! Was nice to see/hear more from Emily as well. You all worked very well together.

I deeply appreciate the "don't blame your LBS" message in the wrap up for the recall discussion.

Probably the best episode so far. I think it's more interesting to hear you guys go deeper on a topic rather than trying to rattle through lots of stuff bit end up just waffling a little bit or arguing the toss about aero! Keep em coming, and get Nic back again!

[@DaveCM]

"Shimano's a reputable company." I have my doubts. They have known about this issue for years and they continued to ignore it. They clearly didn't even change their quality control or manufacturing process obviously. It kept happening even on the new versions. I don't feel sorry for them at all. The kept producing a bad design.

[@Daniel-dj7fh]

How do you obviously know that they haven't changed their qc and manufacturing?

[@Thomas5937]

⁠@@Daniel-dj7fhbecause every single 11 speed dura-ace and ultegra crank for 7 straight years has the exact same defect. The issue isn’t one that can be resolved through better QC. It is a fundamental design defect. Every single one of those cranks will fail if used long enough. Shimano knew this and consciously chose to continue producing and selling them.

[@mctrials23]

​@@Daniel-dj7fh Because they knew about the issue for years and didn't fix the design. They fixed it in the next generation of cranks but fundamentally they didn't do what many companies do and fix issues within existing designs. It was never a QC issue, it was a design issue that caused problems under certain circumstances. Part of the issue is that companies are fundamentally profit driven and they will almost always do a cost analysis to see what they should do. They should have nipped this in the bud as soon as they realised and changed the design and put their hands up but they hoped it would just tick over until everyone was on 12s and they hoped that not enough people would suffer failures to cause big problems for them.

[@antitainer3761]

Because they are recalling around 2.8 Mio units produced over roughly ten years. Issue is known and well documented - glueing carbon directly on aluminium is shite, end of story

[@dainiusvysniauskas2049]

[@garethmartin4821]

As Shimano have known about the issue for a very long time one would hope that they have been making extra cranks to cover this before they made the announcement.

[@PHHE1]

I don't really understand the durability point with jockey wheels? Changing them is a literal 5 minute job, 10 with shifter cleaning? Of course it would still be far better to change them even twice a year instead of paying 100x more?

You need to be interviewing Josh from Silca about vibration, tyre pressures etc, he explains it all so well and gives practical advice (the most important being experiment and keep notes)

23:00 that’s not how aero works: yes from 40km/h it matters more but even from 20km/h it can make a difference. And don’t forget that in a lot of gravel races there are paved pieces where those pro’s go even faster than 40km/h

[@Pseudynom]

I’m really enjoying hearing and seeing more of Emily. As a woman in the sport, it can get a little bit tiring listening to dudes talk. Thanks for bringing together well-balanced and thoughtful shows. I enjoy listening to you guys, but Emily is a big part of what sets this show above the rest. 😊

[@8rk]

I have a lot of anecdotal experience about comfort / speed thing that aligns with what Nic is saying here as well. I used to run latex tubes, for example, which lose quite a bit of air over night. On the days I feel like I'm going faster with no effort, I would also realize I forgot to top up the air in the tire and it would be around 35-40 psi. Didn't feel like it slowed me down at all. Quite the opposite! Also on longer rides like 4.5 hours. At the end of the ride sometimes I'm miserable and struggle to even keep up the endurance pace. But inevitably I have to go over a 10-12% hill on the way back home and I get up, give it a push and my legs feel amazing. So it's really my whole body that is fatigued from the riding. My legs and my lungs are completely fine and fresh. As a result comfort is super important to performance for us everyday people. Pros with all the mobility / core work, the massages, the years and years and miles and miles of riding are able to be comfortable in extreme positions. The vibrations hit them not as hard because they also weigh less. Also they are faster so they get affected less by rolling resistance. All in all we'd really be faster if we didn't try so hard to "look" more like pros.

[@denisrogers4358]

Shimano having LBC’s inspect and decide whether or not a customer continues use seems a huge liability for a small Shop. I’d warranty every crank.

[@paulinblack9036]

Awesome episode - Many thanks! Had been chasing a 'click' on my bike for months, checking one thing at a time without success. The click happens every rotation, but is worse when pushing hard. It seemed to disappear when I got caught in a torrential rain storm, only to return when dry. I checked to see whether my crankset was one of the recall items, but it wasn't. But hearing the noise you played has helped, so will be contacting my LBS to get them to check.

Great show, and all three presenters provide excellent contributions, with good pacing. So refreshing to see a rational, evidence-based discussion on cycling kit, rather than the usual historical/conservative/unscientific approach. Big fan of low-pressure tubeless. Not just for comfort and rolling resistance but also for grip.

[@DjRudeboy254]

comfort is the next big thing! I can say that's true. during covid times i had a hybrid bike with a suspension fork and i rode it a lot and put in some time records that i find it hard to beat now, despite using a lighter and more agile road bike at the moment. Then there is that general feeling that i don't enjoy long rides anymore.... i get really hammered by the vibrations. The hybrid was a heavy bike but much more comfortable and i would ride for hours during lockdown periods. My current road bike is much lighter but with no form of suspension. i think suspension makes riding better. the theory that you need stiffness does not hold water as you put in for effort the road also exerts an equal force back to the rider and if there is no way to absorb this reaction energy it all goes back to your wrists shoulders, neck and lower back. making suspension systems that are light and that can be incorporated into the road bike culture will be the next big invention in cycling. And tell Redshift to reduce the prices on their suspension solutions. Prices are OVERATED 😀

[@shepshape2585]

I live in Central Florida, so the perfect conditions regarding humidity and weather. My Ultegra 6800 cranks snapped in half on the drive side. This happened about 5 years ago. Fortunately, Shimano warrantied the crank set and replaced it for free. Of course they replaced it with the same model which is now on the recall list. I'll be taking it to the local bike shop to have them inspect it.

[@cherny1111]

A great way to understand the energy savings by lowering tire pressure is this: - A bike without rider input doesn't go anywhere, which means any movement generated is a result of the work the rider does with their legs - If you imagine what happens at the tire-road surface on a micro level when you are riding over rough surfaces you would see micro jumps up and down where there is a lot of displacement up and down. All of that movement upwards (against gravity) is energy that came from the riders legs but instead of propelling the rider forwards is going to waste by producing vertical movement. - By lowering the tire pressure and increasing compliance over bumps, you may increase the friction/drag of the tire over the surface, but they are able to absorb those bumps and essentially reduce the VERTICAL movement which is completely counter-productive, and instead sending all that energy being produced by the rider towards forward movement instead.

[@johnsfulton]

I watched the folks on gravel bikes deal with what was effectively a range of Mountain Bike terrain with fireroad and road liaison sections. The phrase "taking a knife to a gunfight" came to mind. Absolutely bonkers! One chap remarked he hated throwing his £7K spec Pinarello down those rocky slopes !! Meanwhile on my Giant Reign160/170mm travel full sus MTB, even my teeth were rattling loose.

Couldn't agree more with your theory about vibration on bikes. Ive recently upgraded from a old 90s road bike with 25mm tyres to a gravel bike with 45mm tyre's. The comfort on long rides even on the road is insane

[@gunjja13]

This was so fun to watch and listen!

[@robertrjm8115]

Reducing or even loosing Vibrations is indeed a very efficient energy saver. Up here in the scottish borders the tarmac roads are sometimes so horribly rough, with the asphalt between the gravel fill being worn away, resulting in terrible vibrations juddering and rattling not only of the whole bike but the whole body including glasses and even dentures. Some stretches of road have been resurfaced and when I look at my strava record after the ride I can easily recognise the bad stretches with average speed dropping from 25-26 to 19-20 km/h. By the way I ride a Specialised Roubaix SL4 Elite from 2016.

[@Carlomirandamn]

No official announcement by Shimano in the Philippines. I asked my bike shop (official Shimano dealer) what the update was regarding the recall and they haven't heard anything from Shimano.

[@curtvaughan2836]

I wonder how the common wisdom over some 100 years was that skinny tires at high psi produced faster speeds on tarmac was apparently so wrong. Until the late 80's or so, high psi tubulars were the rule in pro cycling. Is that due to the tubeless technology now available?

[@markriley5289]

Tubeless FTW. I've been running tubeless on my mountain bike for 8 years and my road/gravel bike for 4 years and never had a puncture. Yes it's a faff at times to setup, but do you want to faff at home where it is warm and dry or at the side of the road where it's cold and wet?

[@DallasCajun]

Harsher surfaces reduce the efficiency of the application of power to the road while also introducing a greater level of resistance from the road to the tires. So by reducing vibration you effectively reduce that resistance from the road and improving the efficiency of the application of power.

[@baptistevuerich7025]

Can you do a parallel on the topic of the comfort structure and power transfer with skateboarding? Wheels in skateboarding have been evolving and somehow in the middle of the nineties before cycling got into larger tires. Could it show how speed and technical tricks can be related? Maybe the two disciplines are too far away, at least the contact with the road, asphalt, concrete is a bit similar on the feeling you get. In both you know when you're f***Ed sliding away and your entire focus is needed to save your ass. The grip to the leap of faith.

[@spektrumB]

That clicking creak is something I've have had off and on (more pronounced under power) in a set of Ultegra cranks, that I've replaced a cassette and BB trying to pin point. It looks like I will need to haul it down to the bike shop for a recall. So, yeah the sound is a good indicator. I looked at the crank after the news broke and didn't see anything and I keep my bikes pretty dry compared to those who live in real wet and humid regions, so I assumed the recall wouldn't apply to me.

I am aware of 2 Ultegra cranks failing-mate of mine was doing a 100 mile ride when his crank literally broke as he was riding-I know as I went to pick him up-the drive side crank arm was in 2 bits. Couple of months later and my crank started making a clicking sound and the drive side pedal seemed to be making an eccentric circle. I thought the pedal shaft was bent-even bought some new pedals……it got worse during a big ride so I stripped the crank when I got home. BIG crack up the inside and the 2 halves had completely separated-I consider myself very lucky not to have had it completely fail as I was riding…… As Jimmy said-both our failed cranks went in the bin and we replaced them ourselves.

Ok several points on the vibration topic. #1 Specialized was pushing this in the early 2000s. Remember those Zerts inserts in the frock, seat stays and seat post? #2 you need to go listen to Silca's Marginal Gains Podcast Episode 2 and probably 4 as well. Josh goes into this IN DEPTH but mostly with respect to tire pressure not frame design. Proper tire pressure will yield a faster rider (i.e. you need less watts to go the same speed). I would prefer to ride my 2020 Giant Defy Advanced (carbon) 100% of the time over my Lightspeed Cherohala (Ti) because it is a more comfortable ride even though the geometry of the Cherohala fits me better. The Giant absorbs more vibration AND is lighter. Win win in my book.

I'm sure one of the main reasons cited for going road tubeless was lower vibration losses from running lower pressures so higher speeds, especially over rough roads (pretty common in the UK!) as well as offering better comfort meaning less fatigue over long distances. I had the first Roubaix with Future Shock and loved riding that bike. Really felt like it was looking after you which encouraged you to ride it hard for a long time, and was amazing at the end of long events/ sportives/ audaxes when you were most tired.

Bianchi's Countervail technology has been around for a few years now :) And it works great! Of course, larger tires can replace this technology to some extent. But anyone who has tried Infintio CV on rim brakes knows what it means to have a frame with this technology. So yes! Vibrations should be the next thing!

I got round to looking at my tyre pressure using the calculator on the Silca website. I went down about 10-15 psi and I can definitely feel the difference. I'm a 100kg rider (good on the climbs - not!😁)so am still way up there pressure wise (85-90psi) but the difference was noticeable.

[@Daniel-dj7fh]

What type of tires do you run. I was told to not run that high of a pressure on my 700x42 continental road speed's

[@craigdovebloke]

700 x 25- old school because of rim brakes - Conti GP5000 or Schwalbe ones - so pretty premium tyres. @@Daniel-dj7fh

I must say, Nic is not your worst podcast guest. But I'll also point out he's your first podcast guest.

[@liambarker6953]

I live in Aberdeen and have the affected cranks on my summer bike. It's done about 3,000 miles since mid 2017. The cranks have inspected and no issues found. I wonder where I'll stand in two or three years time if they do eventually snap.

[@TheBencount]

Hey Cade Media Team Thanks a lot for this amazing video. I really enjoy watching your content and as a mechanic myself, this one featuring Nic was of particular interest to me. Still, all of your vids are really enjoyable. Though, this time I realised something (because it didn’t happen in this video) that has been bothering me for a while now; would it be possible to tell Francis to stop interrupting peoples sentences? It would make the podcast even more awesome to listen to. Thanks and keep up the good work.

Great podcast. Nic brings a lot to the table. However, when it comes to the Lefty ..... #1, it's lighter, stronger and stiffer than traditional shock fork. It takes a lefty hub but otherwise the wheel is no different. Also you can fit them to a variety of brands. I know a couple of guys who race Yetis and run lefty forks.

Mid October is the estimated shipping date for replacement crankset and I was told its a credit on your account not cash in your bank account.

With regards to vibration loss in paris-roubaix: the biggest gains are still in the tires, all other parts are small gains and mostly heavier / less aero / more prone to failure etc., so not really worth it. Most cobble sections are 35-38K/hr affairs but don't forget this is a 250K race with a very hard start on mostly smooth asphalt going 50K/hr for 2-3 hrs on a rolling circuit.

[@danc1829]

My ultegra crackset 6800 got sent off yesterday. No idea when I'll get my replacement 😢

[@hananas2]

Here's a potentially interesting under/overrated thing: Belt drive! For wet places like the UK or Belgium where I live I think they're underrated. Bought a cargo bike with a belt drive and now I'm building a daily / touring bike with a belt drive because I want nothing else for year-round daily commuting anymore. Also the oil change on Alfine 11 / Rohloff is a godsend

[@rok1373]

Really enjoying seeing the different people involved within Cade Media on the platform. Might be a daft question, but with Shimano saying 2012-19 is possible affected. What is there to say that if I bought a new bike in 2023, that it hadn't been fit with a 12-19 groupset? Or is there some sort of condition where the groupset must match the year of the frame?

[@tornagawn]

Vibration? Yep, I had a Girvin Flexstem before we had decent suspension forks….I’ve had a USE suspension seatpost for years….it’s a spring/ elastomer thang which I’ve always said is great at removing high frequency trail buzz, as opposed to ‘suspension’ And whether it works or not…(probably not) my Spesh Allez has the elastomer Zertz inserts in the forks and seatstays, like the old Roubaix frame.
