SRAM Force 1 AXS E1 12-Speed 1x 50T DUB Power Meter Crankset

The SRAM Force 1 AXS power meter crankset puts a spider-integrated power meter that measures left and right leg balance on carbon Force 1 arms, with a 50T X-Sync aero chainring and a SRAM DUB spindle. SRAM rates its power readings as accurate to +/-1.5% and unaffected by temperature changes.

It's offered in 160, 165, 170, 172.5 and 175mm. SRAM describes it as the lightest and stiffest integrated Force power meter it has developed. The 45mm chainline suits road bikes, and the DUB bottom bracket is sold separately.

Who It's For

• Road and TT riders on SRAM 12-speed 1x who train with power
• Riders who want left/right balance data without pedal- or arm-based meters
• Riders who want a large 50T aero 1x ring
• Consider a different crank if you need a 2x setup or a smaller ring for gravel climbing

What to Look For

• Spindle interface: SRAM DUB; bottom bracket sold separately.
• Chainline / frame: 45mm chainline, listed for 135/142 road disc hubs.
• Ring and mount: 50T aero ring on SRAM 8-bolt direct mount; 12-speed.

Key Features

Spider-based power meter. The meter is fully integrated into the spider and measures right and left leg power balance. SRAM states accuracy within +/-1.5%, unaffected by climate conditions during a ride.

Carbon Force 1 arms. Carbon arms paired with the aluminum aero ring make for a light, stiff and durable crankset, according to SRAM.

DUB spindle. Fits SRAM DUB bottom brackets; confirm the version for your frame shell.

50T X-Sync aero chainring. Mounted on the SRAM 8-bolt direct-mount interface, the aluminum ring's X-Sync teeth control the chain on a 1x setup.

Five lengths, carbon finish. 160-175mm with 9/16" pedal threads.

Rider Intent Summary

• Biggest strengths: Dual-sided spider power data, stated +/-1.5% accuracy, and a large 50T aero ring.
• Tradeoffs: 1x only, road chainline, and the DUB bottom bracket is extra.
• What makes it different: Power measurement built into the spider of a Force 1x aero crank.

Victory's Take

We'd recommend this to 1x road and TT riders who want balance data from the crank, and Victory Bicycle Studio can set it up and pair it during your fit.
