Cheers Tangent. I bought a 68/113 from the VERY nice peeps at Chainreaction ( they're letting me do a swap for a small admin fee...bless ). Trouble is it seems MILES out! Initiallay, I tried a 73/108 ( it was free ) but that was so close I knew the chainset was gonna be a hacksaw at the first sign of flex.
I was wondering, as it's a Syncros chainset, could I use a 68/108?
