TECHNOLOGIES

GXP - GXP's gutter seal design cuts friction, durability and weight - improving both feel and performance.

BB30 - Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability, and stronger crank construction.

PressFit30 - It's all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30 mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are house in nylon cups which will be pressed into the frame bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong the bearing life.

X-SYNC - SRAM X-SYNC 1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no limitation.

PressFit GXP - A variant of the external GXP bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. It requires no change to the crank spindle length and diameter.
