Sram Red AXS D1 DUB single chainring 12-speed road bike crankset

The single chainring allows you to further refine the gear range depending on the terrain. And there are disciplines where this is particularly useful. It consists of carbon cranks with an aluminium chainring. X-Sync technology ensures perfectly controlled indexing and chain guidance. It also features a DUB axle, which offers greater rigidity and lightness than the previous version. The bottom bracket will also have a much longer lifespan. This crankset can also be upgraded (modified) to a Quarq power meter version by purchasing the specific spider (optional). On certain versions (48 and 50 teeth), the chainring is solid for greater aerodynamics and rigidity. The new Sram 12-speed road chain must be used with this version of the crankset.
