Tapering wall construction to minimize weight.

Massive external bottom bracket cups house 35% larger ball bearings than internal systems, yielding vastly improved durability.

In addition, bearings feature a special “full-complement” construction. This doubles the amount of ball bearings in the cartridge & greatly increases it’s load carrying capacity.
