Right, building up my bike, and i go to stick cranks onto the new bb, (122 length) and doesnt frigging fit, the chain ring touches the frame, its only a 20 tooth ring, what the heck can i do! I dont wanna do a smaller chain ring, as ive just baught a king cog for rear and it will be useless if i change ratios, the bb is long, and the cranks dont hit the stays. Oh bloody heck, why does the crap always land on me. Any suggestions, the cranks are middleburns
