Redline BMX Bottom Brackets BB

Redline Bottom Bracket

Redline Bottom Bracket sealed bearing. Sprocket adapter included that converts 22mm sprocket holes to 19mm.

This American Size Sealed Bottom Bracket works with the Redline Flight Cranks we sell.
If your Frame measures about 2" in the BB shell then you need the American Size BB. Most all Retro Old School Frames have the 2" BB shell and use this American size bottom bracket. If your frame had a one piece crank it would take an American BB if you were upgrading to 3pc cranks. The 19mm is the diameter of the bearing and axle. The axle is also called the spindle. This crankset uses a hardended steel chromoly spindle.

Redline crank are install quatie easily because of the splined design of the crank arms.

The Rant BB install tool will help you press your bearings into the BMX frame if they are are tight fit. They usually are a tiogt fit and require a pressing tool. The Rant tool is only $9.99 and can save you from pimding on the cups with a hammer.

All Redline BBs are currently made in Taiwan.
