First post here! Disclaimer - I did try to search first to get an answer to this question. I recently completed a Klunker build and had a local bike shop help me with the bottom bracket purchase and assembly. My issue is I don't think they did it correctly. The bottom bracket was shimmed and seems a bit too large. The crank is a Truvativ Stylo Single Speed 1x 33T Crankset ISIS Drive 175mm. My question is this - does anyone know what BB setup is the best to use on this frame? I'm just looking for some guidance here. Thanks for any help in advance!
