SRAM RED DUB 1×12-speed 170mm crank 42T

Triathlon. Time Trial. Cyclocross. Some disciplines are made for 1x. And while the X-Range™ 2x set up has integrated much of the simplicity of a 1x system, there are still times when a single ring is best.

Technologies

DUB™
The unit consisting of crankshaft and bottom bracket is the core of the DUB technology. Here stiffness meets durability. Sram is has gone a bit further and made everything even simpler and I’ve done my job better. It is decisively the system approach through the integration of chainring, crank, shaft and bottom bracket, which means better drive performance.

Exogram™
The new Hollow Carbon Construction starts in the crank arm and extends into the cranks’ spider. It maximizes the stiffness to weight ratio.

X-SYNC™
SRAM X-SYNC™ chain rings 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™ chain rings 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.
