SRAM GX Eagle T-Type 12-Speed 32T DUB Boost Power Meter Crankset

This SRAM GX Eagle T-Type crankset hides a Quarq power meter inside the DUB spindle (SRAM calls it DUB-PWR) and measures left-side power to calculate total watts. It pairs aluminum arms with a 32T T-Type chainring on a 55mm Boost chainline.

Lengths run 155, 160, 165, 170 and 175mm, all in Dark Polar with 2-Guard arm protection and a 174mm Q-factor. The bottom bracket and DUB spacers are not included.

Who It's For

• Mountain bikers on 12-speed Boost bikes who want power data from a durable aluminum crank
• Riders using AXS components, including Flight Attendant, per SRAM
• Riders comfortable with left-side measurement doubled to estimate total power
• Consider a different crank if you need true left/right power balance, or your frame isn't Boost with a DUB bottom bracket

What to Look For

• Spindle interface: SRAM DUB (28.99mm spindle); bottom bracket and spacers not included.
• Chainline: 55mm Boost, 174mm Q-factor.
• Power measurement: left side only, used to calculate total watts.

Key Features

Aluminum arms with removable 2-Guard protection give this power crank the same durability focus as SRAM's other GX parts.

The power meter sits inside the DUB spindle, so it is protected from impacts and SRAM describes it as compatible with any chainring setup. You still need a DUB bottom bracket and spacers, which are sold separately.

The 32T T-Type chainring uses SRAM's direct mount 8-bolt interface at a 55mm Boost chainline.

SRAM states this power meter is compatible with Flight Attendant and connects with AXS-enabled components. Left-side measurement suits pacing and training load, but it won't show leg imbalance.

Rider Intent Summary

• Biggest strengths: Spindle-protected power measurement, tough aluminum arms and a wide 155-175mm length range.
• Tradeoffs: Left-side-only data, plus a separate bottom bracket and spacer purchase.
• What makes it different: The power meter lives in the spindle rather than the spider, leaving chainring choice open.

Victory's Take

We like this GX power crank for mountain riders who want training data without fragile hardware. Victory Bicycle Studio can confirm your Boost chainline and DUB parts before it ships.
