SRAM Quarq Force 1-speed AXS WIDE Crankset Direct Mount Power Measurement without Bottom Bracket DUB 40T It's the best of both worlds. A light and stiff direct mount chainring with precise Quarq power measurement elegantly hidden in the DUB spindle, allowing you to discreetly collect the data you need for your progress. This allows you to focus your attention on the breathtaking finish of the carbon crank arm. The Wide crankset fits road and MTB bottom bracket standards, allowing frames to accommodate wider gravel tires. The SRAM Quarq Force 1-speed AXS WIDE Crankset Direct Mount Power Measurement without bottom bracket and with 40 teeth is the perfect choice for anyone seeking precise power measurement with maximum versatility. This WIDE version of the proven Quarq Force crankset is specifically designed to offer broader compatibility, making it ideal for modern gravel bikes and mountain bikes.
At the heart of the power measurement is the innovative axle-based DUB-PWR unit. This highly developed technology reliably measures power on the left side and calculates the total wattage with Quarq's accustomed precision. One of the outstanding features is the extremely long battery life of over 400 hours, which typically lasts for a complete season without needing a battery change. And should a change be necessary, it's incredibly simple and quick thanks to the user-replaceable AAA lithium battery.
The longer DUB crank axle is a crucial feature of this WIDE version, as it fits both road and MTB bottom bracket standards, offering unmatched compatibility with all manufacturers. Durability and user-friendliness are ensured by the proven DUB bottom bracket, known for its longevity and easy installation. Even bad weather is no problem for this crankset: it is IPX7 waterproof tested, meaning it is fully protected down to a depth of 1 meter for 30 minutes. Despite all these features, the crankset remains astonishingly light, with an added weight of less than 40 grams compared to a standard crankset. Its compatibility with common rear dropout widths of 135 mm, 142 mm, and Boost also makes it extremely versatile. With the SRAM Quarq Force 1-speed AXS WIDE Crankset, you get a precise, durable, and reliable tool to optimally monitor and improve your performance on the bike, whether on the road, off-road, or gravel riding.

Technologies X-Sync SRAM's X-SYNC 1x chainrings provide the highest level of performance and durability. The tall SRAM X-SYNC tooth edges engage the chain earlier than traditional triangular shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfered edges, help manage a deflected chain. To provide the best possible performance in muddy terrain, the X-SYNC chainrings feature mud-clearing recesses for the inner chain links and rollers. Made in Germany, X-SYNC chainrings are an integral part of SRAM's 1x drivetrain.
