In my teenage years in 1960s England, life was simple. Frames were built by a handful of specialists for enthusiasts using standard tried and tested materials and methods. Campagnolo although pricey was absolutely the best equipment to aspire to, and we built up our bikes ourselves. No big business mega-marketing, no 'this year's model' unnecessary changes from year to year, and no direct sales - just good local shops with good mechanics.

[@taichihead42]

Fantastic comment. You summed it up in a nutshell. I raced in the 80's All my friends bought a steel Columbus or Reynolds frame and built it themselves with basic tools. The bike shop was the place to go for everything, no internet and like you said everyone wanted Campag parts. Today i steel ride a steel Italian hand built race bike that i built myself.

[@nerdalert545]

The broken steer tube is a very common and very well known issue with this frame in particular. About half the bikes on a certain pro team, which I cannot disclose, have had frames replaced. If it were an installation issue, the pro team mechanic would no longer be with the team.

I got a 795 RS blades too, I hate the D tube... yes the handle bar and fork will always be strait but the way that the fork is held in place it not great, it always loosen and you need to go over the torq spec to stop the constant loosing of the fork. I am pretty shure he way went over the spec!

[@82vitt]

Exactly how many failures of those fork steerers have there been since that frameset has been brought out to the market in 2019? This is the first I have heard of. If failing parts are a certain proportion of the whole production, we can talk of an issue. If it is only one in 5 years, then its likely due to a user error i.e. lack of regularly inspecting. It didn't just shear off out of nothing, there must have been signs on the steerer surface before it snapped.

[@Paganizondaf650]

Map deck likes them for their above average quality control and finish. They offer mechanics perspective, and before someone like hambini mentions the downsides of a non-round, smaller fork steerer, most people don't take note of stuff like this. Still, I don't really feel there's much to say about this from them. Failures happen everywhere. Unless it becomes a major issue it's just a one in 10.000 bikes type of thing

[@Gareth-pu5so]

Looks were well known for failures back in the early 2000's. Frames and forks. The Mizuno was the fork to have back then. it's a shame because they all look great. I never heard of any track frames failing thankfully.

[@ExpilatorMC]

The steerer broke exactly at the bottom of the stem, so maybe overtorqued stem bolts?

3D printing of parts is cool and all, but if you're using a regular old 3D printer that has the X, Y, and Z axis, it won't ever be able to make a great circle/arc shape. You'd have to print parts, then use humans to clean them up, and you lose the speed savings. The other methods of 3D printing are so expensive at the moment, not sure if useful for bike parts. The easy stuff like Garmin mounts are great candidates for 3D printing, but a hub? I'd pass, for now.

[@gungadinn]

Graphite reinforced plastics done correctly are a great thing. The thing I learned building GRP composites fr aircraft, is you don't get good for cheap, or from low skilled persons. Seen a lot of black aluminum designs, where the fittings were metal, the tubes carbon fiber. Works OK, but the bonded joint needs to be clean and the proper adhesive used. Also, IMO, the weight savings were minimal. I own 4 Lansky designed Lightspeed bikes, three AL6V-4 and one from 3.25ti. Light weight, easily inspectible in the event of a crash. Can't say the same for carbon fiber. How many riders do you know that tap checks their frame? Absolutely nothing wrong with Reynolds 853 steel. It's a life time bike.

The bike comes "pre-assembled" basically the bike is complete, with wheels detached and steerer sitting sideways in the box. All you, the customer, have to do is thrown on the pedals, wheels, and align the headset. Depending on the brand you may not even have to align the headset. But i do wonder how a lay person without a torque wrench will manage things. I know Canyon use a single size of torx head for all of their fasteners, and a crappy torque wrench, but it works well enough to put a bike together.

That would describe the very geiger-esque design, and the inability to spec, design or create a round hole. Machine learning is foolish, and almost always a waste of time, its being sold to management structures as some magic black box of solutions to all of their problems. but in reality it is a dumb child stabbing in the dark with no real knowledge. The sooner the Machine learning fad dies the better. Put it back in the "this is a thing that engineers do to assist their design approach" rather than "this is the entire engineering design approach".

Nord VPN can gargle my orbs with their history of covering up data breaches.

[@RReese08]

The way I see things going on with the bike industry, every step they make forward is another step towards oblivion. Questionable design, engineering, marketing and business practices can get you only so far before the bottom drops out. The only question is who will fill the vacuum when Trek and others go away, and will they be better, worse or more of the same shit just in a new wrapper until they sink beneath the waves. As for bike shops, I’d like to think that their existence will always be required, because while the market may keep demanding more hi-tech products - or the industry thinks they do - 99.99% of said consumers will still not know fuck all about their bikes and how to properly maintain them. What I suppose will happen is - at least here in the US - is that most traditional independent shops will disappear and serious outdoor gear/fitness stores such as REI will have enlarged bike repair departments. The shops that will survive will be very high-end or specialty operations with no ties to any particular brand, and they’ll offer quality service that can’t be matched. I Know this is possible because I know a gent who owns a tiny shop in my area of Los Angeles, and he caters to the sub-basement customers with used, old, and oddball bicycles and products. The stuff the mainstream cycling media and market ignores. But he’s made a good enough living over the years to buy himself a house - cash. So it can be done, if people are willing to put their backs into it, not fuck around, not let themselves be victimized by the big manufacturers, and if they use their imaginations and be part of the communities that they’ve settled in. As always, the worst enemy of the bicycle industry is itself.

Perhaps it is time to start mandating bike manufacturers to start adding stuff like kevlar to these steerers so you could maintain at least some connection even if all the carbon cracks. Dunno whats best, but surely there are some that are compatible with carbon fiber.

[@gam1471]

Agreed; I've often thought this as well. In the days of steel racing frames, the roads of post-WWII continental Europe were in poor condition. In case of steerer tube failure, hardwood dowels were tightly inserted into the tubes as a safeguard. Here in the UK, it wasn't considered necessary.

You don't know the half of it. This fork needed a mass recall, but I'm guessing LOOK can't afford to do that. I have to write this from an anonymous account because I can't talk about it. We have multiple 795 blade forks with this failure sitting in a box. To make things worse, the crown of their forks are a different angle, away from industry standards which means you can't swap the fork for competitor brand. Look has also run out of these forks and isn't producing more. And the plug in the steerer is shorter than the stem height, so you're compressing the tube with no plug behind it for several mm. As an experiment I took a chunk of this fork steerer and placed it in a vice. In one direction it was indestructible, the other direction it folded like paper.

If it turns out that the bottom of the nut isn't below the top bearing then it's got all the load on the outside and a sharp edge on the inside at nearly the same place, so fold here I guess. I don't know, I'm not an engineer's hairdresser's arse, but I remember the nut being further down inside the head set.

The only place where steerer tube failures like this are relatively common is on trials bikes, which get massively higher peak forces and use longer stems. Ali Clarkson put up a video recently trying out two trials bike geometries back to back and had a very sudden steerer tube failure while hopping between 2 rocks - it made for a fantastic video thumbnail and he got away without a mark on him, so all good that time, but fatigue failures like that scare me, because short of strain gauging the bike or regular measuring of the load deflection behaviour of each component to compare to the a baseline value, it's almost impossible to spot some of these cracks before they fail suddenly. Last bad one I had was a pedal axle where the stump of the axle gouged a chunk out of the inside of my knee - the moral of that story is don't retire high mileage pedals to a trials bike.

@@peglor I'm a bit confused here. When you mentioned trials bikes, I thought you were referring to road time trial bikes. Then I read further, and it's clear that this isn't the case. Is there a typo here - do you mean a trails bike, or something else? I assume you're in the USA - I'm in the UK, so maybe there's something in American cycling that I'm not up to date with?

@@gam1471 Look up bike trials to see what I'm talking about - it's one of the more obscure bicycle sports that's still supported by the UCI. It actually blows my mind that you can be based in the UK and not have heard of it given the UK is one of the top countries for trials riding (Spain is probably number 1, even more so for mototrials), but if you've never looked at off road biking at all, or hung around industrial estates and town centers in the evenings and weekends when people go riding bikes there, it's believable that you've not heard of it. If you want your mind blown, look for videos from Charlie rolls and Ali Clarkson to see some ridiculous UK based riding - Danny Macaskill from Scotland is probably the most famous street trials rider in history, with his style being a fantastic mix of BMX and trials riding, but he's more in the style of BMX videography where he takes hundreds of attempts to get the perfect version for the video, while in competition, riders need to do it perfectly first time. As a sport it's similar to motorbike trials (Which it originated from), in that competitions involve riding through a marked course without touching anything but the tyres off it. Practice on the course is not allowed - walking the course is allowed beforehand, but nobody gets to ride it till their competition run. Touching anything but tyres on the ground is a dab, and once you hit 5 dabs, put both feet down at the same time,leave the course boundaries and a few other technical things, it's a failed section. Mototrials and biketrials have diverged recently on the scoring, with bike trials adding a positive score for each gate cleaned (10 points per gate, usually 6 gates per section) as well as counting dabs. This allows riders who get most of the way through the section but get to 5 dabs near the end to get credit for going further than someone who gets a 5 right at the start. Any gate a rider dabs on they don't get the points for clearing, so generally the positive points determine who wins.

@@peglor Thanks for enlightening me with your very full explanation and what I need to watch - it's much appreciated. I've been impressed by the bike handling skills I've seen on KZbin as a result of your reply - just incredible! I've followed the road and track cycling scene for many years, but not I confess mountain biking, and that's why trial riding is new to me. I usually read the UK's 'Cycling Weekly' magazine, which doesn't cover much else. I've always been aware of the mountain bike scene, but somehow I've never got round to learning much about it - and until today I wasn't even aware of trials riding. I know, I know.....I've been cycling since 1960, how is that possible? (!) I enjoyed watching the Olympic mountain bike racing very much, so obviously I need to broaden my horizons. I'm 75 tears old, so I won't be having a go at trials riding! Thanks again, 😊

Trek had a shipping box patent back in 2021, they said back then it was just for China D2C but seems it's been a long running plan.

Super useful stuff, thanks.

scary to LOOk at that failed stearer :D

Speaking only for the USA - gravel is the hottest segment in cycling. Lots of local bike club events in addition to the national sanctioned races.

Loosely hanging by the cables ain't gonna save ya. If my man didn't rapidly reach destination fooked, it's solely due to superlative skills and luck.

Internal cables week headtube external better easily to maintain

[@helloweeny]

You sort of alluded to it but there's little chance of the next big manufacturing centre being India. There are some massive internal and geographical issues that mean this won't ever happen. They will probably just be a provider of services like software development.

[@ptmguitar]

It's simply impossible to get through to people on the matter of their choices being bad. Anyone spending 10-15k on a road bike has too much money to think they're doing something stupid, but that's how it is.

Hookless head tube, what could go wrong?

[@johncoates6039]

E-bike in my neck of the woods equals. Lazy riders People going the wrong way Speeding on side walks DUI individuals finding a way to keep transportation Strava thieves ….i worked at a bicycle shop for 17 years…if I was still there I’d quit before I sold an e-bike to anyone who didn’t “need” one. I get “need” is subjective but just to avoid working harder to go the speed you want is unacceptable…..to me. You gotta earn that s**t! Big love hambini! Every time I get excited about a “new aero fast bike” that’s cutting edge you talk me down😂

"Another D Shaped Failure" ... and when will we see Cannondale's delta shaped steering tubes failures?

[@Paulklampeeps]

That steerer tube is tinyyy

[@JordanColeman-r8w]

I was riding my hairdresser last night and she had a major failure, unfortunately she wouldn't let me take pics 😒

[@silva4428]

These catastrophic failures with carbon frames, forks, and stems will keep me riding with aluminum or titanium for a long time. I just can't trust companies working with this material yet, too many outsourcing and lack of quality control. I prefer to trust the material itself and its resistance to human error and greediness.

[@pierrex3226]

Lol. Maybe you still trust horses more than planes, too. You'd be wrong btw. Planes are safer.

[@silva4428]

I trust planes because the market is highly regulated and safety is paramount. Carbon bikes used by amateurs, not so much.

[@rosomak8244]

You trust titanium welds?! Aren't we a bit naive here?
