SRAM RED 1 DUB crank Carbon Road 1x | Aero 50 teeth
The previous version was already one of the lightest cranks on the market. Thanks to an optimized layer construction of the hollow carbon crank arms, the engineers were able to reduce the weight of the 2024 version by another 29 grams. The proven SRAM X-Sync tooth profile with alternating thick and thin teeth (narrow-wide) ensures a secure fit of the chain on the chainring. The flat aero chainring reduces drag and has been specially developed for triathlon and time trial bikes. However, if the crank is used on other bikes, the aero chainring can easily be replaced with a conventional chainring with fewer teeth. The crankshaft was developed for the new DUB Road bottom bracket standard for a wide range of crank applications. The crankshaft is compatible with all standard bottom bracket housings via the corresponding DUB bottom bracket. With the SRAM AXS Powermeter Kit available in our store, the crank can be upgraded to a power measurement system if required.
