Cycling Cleat Problems & Should I Swap My Tyres? | GCN Tech Clinic

[@tomeklubomir]

Hi @gcntech Why can’t I unclip after fitting a brand new set of Shimano SPD-SL cleats? When will Shimano realise this problem and redesign their Cleats or Pedal release mechanism? Why do I have to resort to filling down the rubber tips (yellow, blue or red) that are making contact with the pedal release mechanism and preventing it from smooth unclipping? Why doesn’t Shimano sell replacement metal SPD-SL pedal wear plates? Why does my perfectly fine pedals (bearings and body) have to go to landfill when worn wear plates start causing knee problems? By changing from screw-on to bonded wear plates and by reducing the size and on some models individualised the contact patch, they made the problem worse. Rant over, why do I bother anyway, I’m currently moving to Look Pedals because of the issues stated above and the fact decent quality Shimano pedals became pretty unaffordable compared to competition… Please put a bit of pressure on Shimano to get their act together… Thank you

#askgcntech -- There's plenty of bike-brand specific sealants like Slica and Stans No Tubes, but what about the "lesser" brands like Slime (here in the US). Are they "super good enough" or should I really spend more for Slica/Stans? I'm not a racer, just a recreational rider who does about 120 miles a week.

#askgcntech Hi there! Any thoughts on Silca's new "Stripchip"?

#askgcntech how do I avoid getting water in my wheels when cleaning. (I’m running Inner tubes if that helps) Thanks

[@niles_stone2742]

Yes, I’d like to see the out front vs solo test for aero gains. I mostly ride solo, but the question is always on my mind when I hear aero results.

[@bateriayvr8988]

An issue I came across when I replaced my GRX chainring to a larger big cog was also to be mindful of the fact you'll probably need to raise the front deraileur hanger slightly in order to give clearance for the new chainring. The extra teeth on the bigger new cog will make it closer to the hanger than it was with the smaller one, giving less clearance then before (in my case, the chain rubbed after doing this).

#askgcntech Assuming two cyclists (Rider A 60kg Rider B 80kg), with the same CDA, are riding at the same speed, into a constant headwind (15mph), what is the relationship between Rider Power, Rider Weight and Windspeed? What effect will increasing the windspeed have for each rider, and is it a linear correlation? (3 points) For extra marks: Discuss if the headwind is increased to 20mph, what affect will this have on each riders power, if they were to maintain the same speed?. (1 point)

The Tubolito TPU tubes I carry work with both 650b and 700c tyres. Really useful when I run my ex GMBN Orbea Rallon in either full 29er or mullet, 29er front and 650b rear.

[@JFomo]

The PZero Race TLR are still heavy but they are bombproof when it comes to puncture protection. For Falls Creek I would still run a fresh set of Vittoria Corsa Pros 😆 Good luck at 3 Peaks.

[@matt_acton-varian]

700C/650B Inner tubes - the 700c inner tube is a wider circumference and won't fit properly in to the middle of the smaller rim. I think that the advice of a TPU spare tube is the best option in that scenario.

[@bchearne]

1:31 the best way I’ve found to service cup and cone bearings is to replace them with sealed bearing hubs

[@nwhiting84]

Regarding the addition of a 52t chainring to a compact groupset... I ran a 52t with a 34t chainring setup for years with no observable adverse issues. I did buy a new chain and cassette when I made the change, and I put roughly 7500 miles on it. I'd say do it and mind the cross chain alignment

[@Chuck6780]

I was personally able to overcome issues with pain in the back of my knees by lowering my saddle just a touch. I initially thought it was my cleats since I had recently started using SPD-SLs (coming from SPDs), but knocking my seatpost down without doing anything to my cleat position did the trick.

[@cuebj]

Tip on cleat position for different feet: spend some time on a flat pedal or otherwise non clip pedal and just look down at where your feet go. Having started with Christophe clips and Binda straps, I got into clipless with the first Look pedals after seeing Lemond and Hinault feature in C4 TdF coverage. But, years later, I kicked a wall hard while sleeping with bed next to the wall. Right foot now slightly twisted outwards and compacted by 5mm. The specialist said it would be the left foot that felt strange on the bike and he was right. Aside from spending a lot of money on a very careful bike fit, start with the assumption that your feet are not symmetrical so the pedals and cleats need not be symmetrical.

[@wertacus]

I've absolutely noticed this too. Still on flat pedals but my right foot tends to sit slightly rotated compared to the left and when I eventually swap over to clipless, I'll take that into account

[@cuebj]

Shimano 600 - takes m back a bit. 1980? Came with Biopace rings. Did tens of thousands of miles in, through, around London & SE. Think I still have the parts in a box in the shed. Life and bike maintenance was simple then

[@coachjohn]

I would love to see some videos that include group ride vs tt when you do new tech or bike videos. Great idea Andy

[@kevingregoire1042]

Oli, science dude ! « massively reducing puncture RISK by using tubeless » is not the way to phrase it. Maybe it’s time to use new words to share the knowledge, something like puncture RESILIENCY. And having a tyre set up with puncture SEALING ABILITY vs CARCASS REINFORCEMENT. Or simplify with the use of FLAT, instead of the inadequately chosen word PUNCTURE. Having a tyre increasing puncture resistance is not the same as having self sealing properties. But those come at the expense of drawbacks. Puncture will happen, Deflation will happen, total flat too. Every one needs a spare. I thought you two might remember 😂😅 Appreciate you guys, big love gcn.

[@feedbackzaloop]

A narrow 700c tube won't stretch that well everywhere: the reinforcement around the valve won't allow it and create a zone of small stretch near very extensive stretch, basically a stress concentrator. Now, a thinner, but still regular size 26" tube is a good compromise, when 650b TPU is rare or too costly. Tubes stretch diameter-wise much better than in width.

[@bobfranklin4695]

How do you tell when the sprockets/chainrings are worn out is there a way of checking against a profile chart?

[@sbccbc7471]

Once they resemble almost like a shark's fin or when your chain is beginning to slip over the teeth consistently whenever you put the power down, time for new ones.

[@feedbackzaloop]

Put a new chain on and see hot it fits. There are short tutorials on this. Meanwhile profile chart is not a reliable tool because teeth have variation in shape for shifting, and there is a significant error in projecting profile onto the paper.

[@swordmonkey6635]

The "group/bunch" experiment fails with variables like: 1 What's the size of the group? 2 What's the spacing of the riders? 3 Where does the test bike set in the bunch? 4 Can the test rider jockey for position in the group? 5 Will the test rider be out front at times or alway in the draft? All of these are N variables that can greatly change the result of the test if changed.

[@overcookit1433]

Concerning the hub maintenance: it is also important which grease you use. A white grease turned rather fast into grey and also was pressed out through the seals (Shamal HPW rear hub), while the green Motorex bike grease stayed green and also remains in the bearings, even in the headset it maintained its composition for years, and dirt had no chance to get inside.

[@gcntech]

That Motorex grease you mention is very similar in appearance to what you find in Dura-Ace components, unsure if it is the same though

#ASKGCNTECH I ride a 12+kg steel mountain bike but because I didn't really have the budget for a road bike. I finally got the budget for an aluminum road bike but I want to know if riding in harder gears would help me be ready for when i get on a road bike. The MTB still uses a 3x chainring which is why i ask the question on training on harder gears. Thank you so much and keep up the amazing work you've been doing.

[@leissp1]

Cleat position Question. First I would check to make sure that the bars and Saddle are straight.

[@michaelsherwin4449]

I have asked this question many times but I never get an answer. Maybe this time? I have the new Trek Domane al 5 4th gen with 50/34 and 11/34 12 speed mechanical Shimano 105. I'm thinking about modifying it to 50/47 and 11/50 with a GRX derailleur for a "half-step" configuration. Will it work? And what would be the pros and cons of such a setup? Thanks?

[@feedbackzaloop]

First, GRX 1x derailleur capacity is not technically enough for 3 extra teeth up front, but it might work. Just like technically 12s and 11s pull ratios are different, but not that much. Second, front derailleur parallelogram is moving so that the smaller ring must be significantly smaller than the bigger. If you move the FD way up for clearance over a 47t chainring, it will be too high at 50 and cause chain drop. Lastly, did you check the gear spacings with gear calculator and surely wouldn't like other ways to achieve "half-step", with maybe 1,5 or 2,5 offset? But then you will definetely need absolutely another setup, very similar to 11s GRX Additionally, sure half-steps are even any good for you? You ready to use FD as often as RD?

[@michaelsherwin4449]

@@feedbackzaloop I'm an armature cyclist, just started last July. That is why I'm asking the question. 1) Wouldn't the 12 speed 105 rear shifter handle the movement of the GRX. What does the GRX know about how much to move except the shifter actuates it? 2) When I look at the front derailleur while the 34t is selected the derailleur cage is already slightly above the 50t ring. 3) I did the gear ratios by hand and they are almost perfectly spaced in between each other along the entire range giving 24 unique ratios. 4) One would not have to use the FD all that often, only when one needs an in between gear. 5) I don't know if it would be any good for me. That is why I asked for pros and cons. I just like the idea and think it would be cool to try. I bet that the GCN Tech members have most of the parts already available (except maybe the 47t ring) and could try this idea in an afternoon. Good or bad idea it is at least an idea worth making a video about.

[@larrylem3582]

@@michaelsherwin4449 Try it yourself. Sometimes you have to try a change to see why it is or isn't a good idea in practice.

[@feedbackzaloop]

@@michaelsherwin4449 oh, it's Di2 we talk here, if i read your "what does GRX know"... Ok then, things get bit more complicated, but simpler. There is no 12s GRX Di2 and 11s di2 is not compatible with 12s Di2 in ant form. Otherwise, mechanically: 1) pull ratio same, pairing shifter and RD shouldn't be a problem 2) ok, if you see the spacing is adequate, try it. But not so sure you matched the position of shifting features on the cage with chain 3) did you consider cadence range? In lower gears the spacing normally shouldn't be that tight. So guessing you need to compensate only top gears, my proposal was to shift half + n times full. Not 1l-1h-2l-2h... but 1l-2l-1h-3l-2h-... 4) if so, what is the purpose of half-stepping at all? 5) pros: you do something extraordinary and learn a lot. cons: you end up with hard to operate heavy system 6) GCN hardly ever try out anything unless it's a two-three video series for mass public. Most of questions picked are not specific but an example for broader audience. So I have to ask you again, or rather you have to ask yourself, what specifically do you not like about current drivetrain and what compromises you could make in order to fix this. Because, well, if one could have it all, there would have been such sollution on he market, even be it very expensive.

I'd replace the rear with the front, so the front wheel always gets a new tire when the rear tire needs replacing.

Is the most likely cause a slight misalignment of one of the rims by a few millimeters, or could the axles possibly be misaligned? Visually, there is nothing apparent, and even with a ruler, nothing conclusive can be determined.

@gcntech not a tech question, but I just started doing zone 2 training.

I'm reasonably fit, done a few centuries (including two "back to back" last year with only one day between) and 120 miles of the 140 steamboat race last year. What does it mean that I can't stay out of Z3? Does it hurt the "base training" goal to just finish the ride at higher intensity or should I cut it short and go home? Thanks.

[@mattkavanaugh5623]

I've done similar cassette swaps and also use a trainer and your current chain should work on the larger cassette as you're only increasing the large cog circumference by two teeth. If you were going to a 36 tooth cog or bigger on the cassette then you might need a larger chain. Try the cassette swap and see if the existing chain works, I'd do.

[@sbccbc7471]

It should be mostly OK, you just need to readjust the B-tension gap between the guide pulley (upper pulley) and the largest cog. As long as you don't cross-chain on small-small gearing, the chain should be under tension at all times.

Being Rim Brake, I looked at several sites and found precious few wheels available for rim brakes. How challenging is finding replacement parts for a cup/cone system (I understood that changing the bearings should be all that's required)? Would you reply with suggestions (sponsorship aside) for an economical wheelset for a rim brake setup, please? Thank you. Love the content and a huge hat tip to Alex and Dr. O for your expertise.

[@sbccbc7471]

Ball bearings aren't the only thing that wear out in a cup-&-cone bearing assembly, the cups and cones can wear out too. I've seen pitted cups and cones before. For some hubs, the cups are part of the hub shell and are non-removable. At this point, a new wheel (or hub if it's a studio-built wheel) is the most logical solution.

I hear a lot of talk about tyre rolling resistance, but I never hear anyone talk about how tyres affect drive train efficiency. In other words, how much effect does tyre choice have on transferring wheel torque to force on the road?

[@feedbackzaloop]

efficiency = 1/resistance. Talking rolling resistance is same as talking efficiency of torque transfer. Unless the special case of grip loss. Then the efficiency is not considered anymore as a proportion of power out / power in and is replaced by effectiveness "ultimate torque >/< resistance torque"

[@kevinmartin7863]

@feedbackzaloop Rolling resistance is mainly about radial forces (compressing and uncompressing the tyre). Drive efficiency is about tangential forces. They are different things.

In the case of NYC bike messengers, the city is pretty much flat, so there's not much descending to do. However, because you don't have brakes of any kind, there's no stopping immediately on this kind of bike. The majority of fixies I've seen sold in small-time bike shops feature a front rim brake and a flip-flop rear hub, a fixed cog on one side and a freewheel on the other.

Reason I tried tubeless was all these stories about puncture protection, blah, blah.... In the ~12 months I ran tubeless I lost count of how many punctures I had and how many ruined tires I burned through.

Make of that what you will, but tubeless for me was an utter disaster and will never again use it on the road.
