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.

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.
