Kogel PF30-24-GXP 46 x 68mm Low Insert Road Bottom Bracket

Kogel Hybrid bearings use premium grade Silicon Nitride (Si3n4) Bearings and premium hardened steel bearing races which are mirror polished to perfection. The result? A long lasting, smooth bearing which provides less resistance and is less prone to failures. These bearings are rated to the Grade 3 / ABEC 5 level - built to spin with minimal friction.

This bottom bracket is Kogel's PF30-24, but with a shallower insert depth. The original PF30-24 was designed to make a rock-solid connection between the frame and crank set. Due to the almost 1 inch deep contact area with the frame, it covers the openings inside the BB shell on some frames. Typically, the chain stay hole on steel and titanium frames. A real bummer if you're trying to route a Di2 wire internally. For these frames Kogel have designed the PF30-24L, same thing minus the insert guide and a few mm of contact area.

This bottom bracket fits all 24mm crank spindles and comes with a GXP reducer in the box for SRAM. Choose road bearings for road bikes, cross bearings for mountain bikes and cyclocross.
