SUCCESS! Thought I was going to have to resort to a Dremel or hacksaw, but alternating between pullers and using quite a lot of force I finally got one to fully engage. The treads on the cranks are trashed but we were replacing them anyway.

If a crank has been on a while trashed threads are common enough. I’ve cut plenty off before now.

When working out maximum rear tyre width, where the gap between the chain stays ( as opposed to the seat stays ) is the limiting factor, what is the recommended minimum gap to leave on each side between tyre and stay ?

eg if the gap is 36mm, would 2mm either side be ok and therefore could fit a 32mm tyre, or is more than 2mm recommended ?

I'm not sure what the recommended minimum would be, but a few things to consider.

Tyre width is nominal, so particular tyre/rim/pressure combinations may not be quite what's quoted.

If the wheel isn't perfectly true(probably not uncommon), or flexes a bit under load, such a small gap may be absorbed by that eccentricity.

You could also pick up road crap that may absorb that gap.

I'd probably want a bit more clearance for most purposes, but you could experiment.

What MM said. Sounds like he speaks from experience

Thanks MM - all good points. So, if say min 4-5mm needed each side, looks like I'm better to stick with my 28mm's :-(

Was hoping to turn my hybrid "city bike" into more of a gravel bike for light trails, but may just stick with the hardtail for those paths

I’m surprised you can’t put wider tyres on a hybrid. 28 isn’t a wide tyre really.

Got something to say?
