Speedline Outboard Euro BB features a BMX specific bearing design that uses special high grade precision ground steel bearings, low friction seals and lightweight lubricant to produce a bottom bracket with as little drag coefficient as possible.
The bearings are held in place by forged and CNC machined aluminum cups that ride on the outside of the BB shell for greater durability.
Compatible with cranks such as our Speedline Elite 2 Pc Aluminum, Shimano DXR , Rhythm, Bombshell and other cranks that use a 24mm spindle size.
