Hi all; I just want to confirm the correct BB to order for this... I have an F900 Optimo frame (I bought it used and the frame was replaced under warranty at some point). I tuned it up and converted it to a gravel bike. Riding last week, it started to creak, so I re-torqued the crank set. Alas the creak has become a click, so it's time to replace the BB.
It's a square taper spindle marked "Shimano 1.37 68" on the cup (I'm hoping to order the replacement before I remove the old one). Is 24 thread pitch a safe bet for this frame? Any recommendations for a replacement? Thanks!
