For better crankarm compatibility. For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride. - One oversized spindle to work across every bottom bracket standard - Gutter Seal Technology drastically improves sealing against the elements - Significantly lighter than GXP system - Sealed cartridge bearings
