Any question answered...

1x11?

which brands should I be looking at?

Bosch are #tester_approved for various reasons.

If I can avoid it, I'd rather

my seat tube is 29.5mm can I 3d print a shim to go from 27.2 to 29.5?

Only if you have access to SLS or similar metal printing tech. Printed plastic isn't strong enough, especially on a big gap like that. 29.5mm seems unlikely (the only odd number which is common is 30.9), so double check your measurement.

JB Weld.

What sort of adhesive am I looking for? I never want it to move again

3M DP460. But surface prep is going to be more important than the type of adhesive. A superb adhesive with shit surface prep is still going to give a shit bond. But if you use it properly, then if you can break a DP460 bond in shear you should enter the world's strongest man competition ASAP.

Q:

Is there still any interest in getting new forum caps made?

Festool
Makita
Dewalt
Bosch
Ryobi

In that order, ignoring prices.

Where can I get a replacement 125mm NDS square taper crank arm in (preferably west) London today ?

Failing 125mm, I'll accept any shorter than standard crankset, the shorter the better while not shorter than 125mm.

Just out of curiosity are you saying you'd be happy to ride around with two different length cranks (e.g. a 125mm and a 135mm)? I've never heard of anyone doing that before.

Ha, no, I'd be looking at replacing both cranks if I can't get a new 125mm NDS

Haha, oh right. That makes a lot more sense

Are these 140mm any use to you? Used for a few 10 mile TTs only, NOS rings choice of 34T or 40T. £20 for the cranks and £10 each for the rings, if you need them today I should be in Marylebone after work.

Those will do nicely sir, PMed

Open Broadcaster can't do the highlighter thing, but you should be able to do that with something like Pointerfocus. OBS needs a little bit of setup, but files are reasonably small. Tons of tutorials on yt.

Thanks for that - think I tried OBS a while back for some livestreaming but will dig out again. Haven't come across pointerfocus so shall take a look. Cheers

Question: is it possible to ride a bike with different length cranks? Why have I never heard of anyone doing this?

Aren't some people after a detailed bike fitting given shoe inserts to even up unequal (effective) leg length?

Hmm, I don't know. But that wouldn't give exactly the same result; you're effectively moving the center of the circle (of crank rotation) upwards rather than decreasing the radius of the circle. And also you're changing the way the shoe/cleat rotates around the pedal axle.

Maybe in a few years we might see Team Sky (et al) 3D printing custom length cranks for each rider. They already do custom aero bars and stems.

But anyway I was thinking more about the frankenbike end of the frankenbike-to-pro-bike-fit spectrum

Foot speed is one reason I can think of.

is it possible to ride a bike with different length cranks? Why have I never heard of anyone doing this?

1. Yes, anybody could do it. Some people do it by accident with small differences, due to inattention while assembling bikes from their parts bin.

2. Because you haven't been paying attention to paracycling, where uneven cranks are sometimes used to provide a balanced ride for an athlete with profoundly unbalanced legs

Why use the word DACHROTISED when it doesn't exist ?

Why use the word DACHROTISED when it doesn't exist ?

But it does exist, it's right there on the packet! Of course, it would usually be spelled dacrotized, but you can see why a modern British English user who knew it involved chromium would use ch instead of just c and s instead of z if they had heard the word but not seen it written down.

Any recommendations for Italy-to-UK man with van?

I must transport the two sewing machines back to the UK, and if the price doesn't change much then a couple bikes too (saves flying with them).

Ideally first week of January.

Any friends? Or?

Thanks - I'll tell B & Q you sent me :)
