Rotor T4730 Asymmetric BB Steel Black
The ROTOR T4730 Asymmetric BB allows you to install cranks with a 30 millimeter crankshaft in frames with an asymmetrical T47 bottom bracket shell with a width of 77 millimeters. The aluminum 7075 bearing shells are completely CNC-milled and then black or red anodized depending if you choose steel or ceramic bearings.
High-quality steel ball bearings and silicone seals ensure a long service life. On the other hand the ceramic bearings will provide you with less friction and a lighter weight.
