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 30mm Spindle cranks such as our Speedline Elite Carbon 2pc, BOX P30 and other cranks that use a 30mm spindle size.
Weight is 250 grams ( 3.5 oz )
