SRAM RED 1 DUB Crank Carbon Road 1-speed | Direct mount
The latest coup from the pioneers of the 1-speed drive. Equipped with light and stiff direct mount chainrings, the RED DUB crank has become even lighter. Compared to the version with spider and chainring, approx. 35 grams could be saved. The SRAM X-Sync tooth profile with alternating thick and thin teeth (narrow-wide), tried and tested in the MTB sector, ensures that the chain sits securely on the chainring. A laser-engraved chainring finish adds durability. The ultra-light carbon crank arms transmit the pedal force to the drive without any loss. The SRAM DUB crankshaft ensures a wide intended use With the corresponding DUB bottom bracket, the crankshaft is compatible with all common bottom bracket housings. With the SRAM Quarq AXS Powermeter Spider available in our shop, the crank can be upgraded to a power measurement system. You can find retrofit chainrings with 38 to 46 teeth in our shop.
