Is anyone else running 170mm cranks on their 55cm mash? if so how close are your crank arms to hitting the actual frame?

crank spacing

I am building one of these up for a customer and am seeing the same thing. In theory the cranks will never touch the bike. We shouldn't see any flex. We are working with a super stiff frame and Campy Record is the stiffest crank in the industry. That is pretty darn close though.

The wider chainstays let us run Vittoria Randoneers in a 700x28 but now we have this spacing issue. I am going to try a Phil Wood in a 118. That's going to kick the cranks out 3.5mm on each side. That shouldn't effect the chain line too bad considering road chains which are much narrower get shifted all over the place AND tolerances are not effected that badly when we do fixie conversions with messed up spacing and random parts.

We'll see what it looks like when it's together. I think it's going to work out really well and I'll let you guys know.

crank arms

Mine are 170's too and the crank arm was actually hitting the chain stays on my super pista, I had to get rid of my super smooth 111mm pista bottom bracket, and get a 115mm.

what 115mm bb are you using

what 115mm bb are you using now? is your chainline off now?

Using a token 115 iso taper

Using a token 115 iso taper bottom bracket chainline is fine

If you're using the 111mm

If you're using the 111mm Pista BB, that looks about right. Damn those oversized chainstays!
