To further enhance the stiffness and efficient power transfer, this particular model adopts the BB30 bottom bracket standard, which offers a 30mm spindle and uses larger, more durable bearings. In addition to this, the Descendant Carbon also boasts a SRAM X-Sync™ 1X chainring. This chainring provides ultra-reliable chain retention, optimised engagement with the chain and consistent performance over all terrains and in all weather types.
X-Sync™: SRAM X-Sync™ 1X chainrings provide the highest level of performance and durability. Their tall square teeth edges engage the chain earlier than the traditional triangle shaped teeth and their sharp and narrow tooth profile, as well as their 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.
BB30: Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.
