Designed for high-end performance and durability the CeramicSpeed EVO386 SRAM GXP Mountain Bike Bracket places its value in its extremely low friction and ultra-high-quality construction. EVO386 began as a design collaboration between Wilier and FSA. Like the BB86, it marries a 46mm diameter shell like PF30 with an 86.5mm width. The extra width allows for more design flexibility and the wider shell allows for bigger bearings. The CeramicSpeed EVO386 SRAM GXP Mountain Bike Bracket comes with the CeramicSpeed Standard bracket that can last three times longer than other bearings thanks to the hardened-steel races and ceramic balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed EVO386 SRAM GXP Mountain Bike Bracket is unparalleled in durability and efficiency.
