New Crank Arm question
 

Hey, I just got a new crank arm set from Bulletproof. They are 170's and im using them to replace my old sugino set because they started to get worn out and round out the square holes. Anyway, will replaceing the crank arms affect my chainline? I figured this is a good time to convert to a 1/8" chain because Im getting a new front chainring as well. Thanks

Assuming that your sugino was the RD and you're using the 103BB the chainline should be the same(45mm on the outside)
