Hi, i just bought a vintage Record Crankset to use in my Olmo bike but I'm not sure if it is compatible with bb that i have.
I have a vintage record crankset and a chorus bottom bracket 102mm italy thread.
So, when i tried to install these parts i noticed that the right crank arm is flat against the side of the bottom bracket (with no gap to free rotation). But, if i install the bb inverted it seems to be a regular fit. I mean, with the bb left side on the right side of the bike. The axle right side of the bb is biggest or looks like.
Anyone could explain me what happens? It's really incompatible or should I use the bottom bracket "inverted" to fit it normally? Or What?
Heres a picture to try to explain easier.
