SRAM Force E1 DUB Direct Mount Crankset - 172.5mm50/37T

The SRAM Force E1 DUB Direct Mount Crankset delivers a lighter, stiffer, and more efficient drivetrain solution for 2x road setups. With carbon crank arms, durable thread-on chainrings, and precise X-Range gearing, it balances performance and reliability for riders who demand seamless power transfer and smoother shifts on every gradient.Key Features and Benefits:One-piece 2x chainring construction: Merges both rings into a single unit. This design increases stiffness and reduces flex under load, leading to more efficient power transfer and a more direct pedal feel.Thread Mount removable chainrings: Uses a secure thread-on interface instead of bolts. This allows easier ring replacement or tuning of gear ratios without disassembling the crankset, reducing maintenance time and giving more setup flexibility.X-Range gearing technology: Widens gear range while keeping cadence changes smooth. It minimises the jump between front chainrings, helping maintain rhythm on climbs, descents, and rolling terrain, improving overall speed control.DUB bottom bracket compatibility: Uses SRAM s DUB spindle and bearing system. This simplifies installation, increases long-term durability, and ensures smoother rotation across all riding conditions.Crisp and accurate front shifting: Integrates with SRAM s Road-Yaw front derailleur system. This allows precise shifts under load, reducing chain rub and improving efficiency across the full gear range.Multiple chainring options (46/33T, 48/35T, 50/37T): Offers a range of gearing setups. This lets riders tailor their drivetrain to suit racing, endurance, or mixed-terrain riding goals.This crankset is designed for riders focused on consistent performance across varied road conditions. The integrated chainring system and X-Range technology reduce shifting gaps and boost drivetrain efficiency. Combined with a stiffer carbon arm design and simplified DUB setup, it provides a reliable and adaptable platform for long-term use and performance gains.Take advantage of a drivetrain engineered for efficiency, strength, and low-maintenance operation. Choose the chainring configuration that fits your goals and get a setup ready for upgrades when you are.Specification:Speeds 12BB Compatibility All SRAM Road DUB BBsChainring Size 46/33T, 48/35T, 50/37TCrank arm length 160mm, 165mm, 170mm, 172.5mm, 175mmChainline 45.0mmBB Spindle Interface DUBChainring material AluminiumBolt Circle Diameter (BCD) Direct Mount (DM)Crank arm material CarbonColour (Crank arm) BlackPower meter NoChainring Offset 6.5mmBottom Bracket Technology 6.5mmChain Technology Road Flattop D1, Road Flattop E1Drivetrain Configuration 2xTechnology (FD) Road-YawFront Tooth Jump 13
