Can I use a SRAM or Quarq power meter spider on my Trek BB90 frame?

SRAM and Quarq power meter spiders are typically paired with DUB crank arms and a SRAM DUB bottom bracket. This is SRAM’s newest interface and is the one we recommend for most frames. However, SRAM doesn’t offer a DUB bottom bracket for Trek BB90 bikes. This is because, due to the larger size of the DUB spindle, a DUB bottom bracket can’t be made to fit a BB90 frame.

However, SRAM also makes RED GXP cranks that work with Quarq power meters and the GXP cranks will also fit Trek BB90 frames (assuming you install a GXP bottom bracket).

SRAM RED GXP

The SRAM RED GXP are SRAM’s top-of-the-line carbon fiber cranks. The cranks feature SRAM’s Hollow Exogram construction resulting in superior stiffness while keeping weight to a minimum.

SRAM Force GXP

The SRAM Force GXP are slightly more budget friendly cranks. Like the REDs, are also feature a carbon fiber construction, but are slightly heavier.

power2max or Sigeyi

We would also mention that both power2max and Sigeyi make similar, spider-based power meters that come on a 24 mm spindle. That advantage to these is that you don’t need to make any changes to your bottom bracket as the 24 mm spindle will fit your current BB90 bottom bracket. Many of our customers go this route as the power2max and Sigeyi are great power meters and installation is easier.
