The Bottom Bracket is what connects your crankset to the rest of your drivetrain. The bearings in the bottom bracket are responsible for converting your energy from turning the pedals into forward motion. Bottom brackets come in more than a few configurations, and must be compatible with your frame.
Make sure you know what type of road bike bottom bracket is compatible with your bike. If you are unsure what type fits your bike, call us at 877-474-3180 to talk to a live technician 10am to 7pm, Monday through Friday central standard time.
