Sram Force D2 DUB Left Crank Arm Without Power Meter

The SRAM Force crank arm impresses with its low weight and increased stiffness. This is thanks to its carbon fibre crank arms, which also feature a glossy surface and reflective "Iridescence" logos. The already proven technology DUB™ also contributes to greater durability throughout the system.

The crank arm is compatible with 1x12- and 2x12-speed drivetrains and features a 8-hole Direct Mount interface for fitting the corresponding chainrings, chainring assemblies or spiders. Chainrings with an integrated power meter can also be fitted.

Its wider chainline also provides enough clearance for large tyres.

Features of the SRAM Force Dub crank arm

• Carbon crank arms for increased stiffness and lower weight
• 8-bolt SRAM Direct Mount chainring interface
  
• DUB bottom bracket technology for increased stiffness and durability
• Can be equipped with a power meter

DUB™ | The bottom bracket and oversized spindle assembly (⌀ 28.99 mm) is at the heart of DUB™ (Durable Unified Bottom Bracket) technology, combining stiffness and durability. The system approach created by integrating the chainring, crank arm, spindle and bottom bracket not only improves durability through optimised sealing but also takes the assembly's performance to a new level.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
