SRAM Eagle 70 T-Type DUB Crankset — 170x32, DUB Wide, Black

This is SRAM’s Eagle 70 T-Type crankset in the 170mm length, built for modern Transmission-equipped trail, enduro, and e-MTB bikes that need durability without jumping to GX or X0 pricing. It combines aluminum crankarms with a stamped steel T-Type chainring to handle high torque riding while staying fully compatible with SRAM’s Transmission ecosystem. Key Functional Details 170mm crank arms with included 32T T-Type direct-mount chainring Forged aluminum crankarms Stamped steel T-Type chainring for long wear under load 3-bolt T-Type chainring interface DUB Wide spindle for 55mm chainline Compatible with optional T-Type bashguards (shared with Eagle 90 / GX / X0) Designed specifically for SRAM Transmission drivetrains 1x12 drivetrain application Black finish Compatibility & Technical Notes Compatible ONLY with SRAM T-Type / Transmission systems Requires UDH-compatible frame DUB bottom bracket required (not included) Accepts only 3-bolt T-Type chainrings Designed around 55mm chainline (DUB Wide) NOT compatible with legacy Eagle (GX/X01/XX1) components NOT compatible with Shimano drivetrains This configuration uses 170mm crank arms Service / Ownership Context This crankset is intended for high-torque riding and Transmission setups. Proper DUB bottom bracket spacing and correct torque are critical for quiet operation and long service life. Fit & Use Signals Good Fit: SRAM Transmission trail, enduro, and e-MTB bikes using DUB Wide and UDH frames. Not A Fit: Non-UDH frames, legacy Eagle systems, Shimano drivetrains, or riders wanting traditional MTB chainrings. Transmission crank only. Not regular Eagle. Most common mistake: customers assume this works with GX/X01 Eagle. It doesn’t. Needs full T-Type drivetrain. Steel T-Type ring is heavy but lasts way longer on e-bikes than alloy. 170mm is the “middle ground” length — good balance of leverage and clearance. DUB Wide = 55mm chainline. Spacer setup matters. Wrong spacing = creaks and poor chainline. Bashguards are shared across Eagle 70/90/GX/X0 T-Type which makes replacements easier. Complaints usually come from weight or looks compared to GX/X0. Functionally they’re solid. Failures almost always trace back to install: dry spindle, wrong BB spacers, preload not set. Who this is really for: riders on Transmission bikes who want durability without premium pricing. Who should avoid: anyone not running T-Type. Mechanic advice: confirm UDH before selling, grease spindle lightly, install DUB BB correctly, torque preload, and tell riders to replace chains early to protect the steel ring.
