SWAP: cranks fc-mc40 4 bolt STX-RC

[Labman]

Stx-rc Crank arms 175
Taper is mint and so are the threads

i want to swap for another 4 bolt crank @170 but the taper needs to be shorter as this stx started to rub on the bb (110mm) which i have never encounted before, :roll: ...

Can i dibs these for poweredbypies as he was after some four bolt ones?

 

[cyfa2809]

What about a longer bb?

because im only running a single 32t i tried to get the crank as close to the frame as poss so i dont need a chain device..

Not as nice but an Alivio 5 bolt is really good for single speed and allows for a shorter BB. Look at my link below. I use one on my Giant.

Many thanks josh for the dibs as it happens I wouldnt mind swapping my arms for some 175's mine are 170's. Mine run on a 110 bb and dont catch. What frame are you using.

Think it maybe crank arm length but im finding it hard to get the sweet spot for my riding position.Plus what man turns down extra length fnar fnar.
