Press Fit 4130 Bottom Bracket
With the ever expanding range of bottom bracket standards available, it's no longer possible to just assume that your crank and your frame are going to naturally coexist in perfect harmony. Rotor's Press Fit 4130 Bottom Bracket acts as the cycling equivalent of a diplomat, convincing your spindle and your bottom bracket shell that peaceful coexistence is the best way. The cups adapt a 41mm bottom bracket shell to house a 30mm spindle.
