so i have a 103mm BB spindle and a sugino crank that says shold use a 110mm spindle, i put it on the other day and it didnt bottom out against the BB casing or anything and goes on and comes off smoothly and rides smooth. just wondering what the problems are with this if there are any? the only difference i can see is that you would have a lower q factor. i know that you are not supposed to do this though. thanks

Chainline is compromised, as well as the possible chainstay - heel
and crank arm strike,

but if thats OK. . then it is..
