The SRAM Force E1 DUB Crankset is built around a one-piece 2x chainring design — a construction choice that removes chainring bolts from the equation, reducing weight and adding torsional stiffness where it matters most: under hard pedalling effort. Paired with X-Range gearing, the tight 13-tooth jump between rings (46/33 or 48/35) means front shifts are smaller steps in cadence, so you carry momentum through changes rather than losing it. The DUB spindle interface is straightforward — it works with a wide range of bottom bracket standards through the appropriate shell adapter, and the crankset is designed to accept a power meter upgrade without requiring a new crank. Five arm lengths from 160mm to 175mm mean you're not compromising fit to run this level of drivetrain.
