Hello there,

i have a roadbike with a 73mm bb shell and i recently bought a tiagra compact crankset that has a 110mm bolt circle lenght and the thing is i cant get enough of it to come out the other side to properly attach the left arm of the crank

This is rly upsetting because as far as i can tell shimano only makes 110m length cranks for compact 2 ring, the only solution i see is getting a new 3 ring crankset for about 100€ and this would mean i have to change my sti shifters and possibly the front derraileur aswell... are there any other options? thanks.
