Our existing models offer an extensive range of compatibility with cranksets from Shimano, FSA, SRAM, Cannondale, and Campagnolo.  Though we may not offer an exact match for your existing crank, most of our models are cross-compatible with other models from the same manufacturer that have the same bottom bracket interface and similar offset/q-factor. 


Shimano Hollowtech II road

While we offer current model left crank options for Dura-Ace, Ultegra, and 105 road cranks, additional component levels and many older groups are also compatible. Shimano road cranks are interchangeable between other component levels that utilize the dual pinch bolt. Nearly all pinch-bolt style Shimano road cranks are able to be interchanged in equivalent lengths. Stages Power R right-side Shimano road power meters can also be used with any Hollowtech II compatible left crank arm.

Shimano Hollowtech II mountain bike

For Shimano Hollowtech II mountain bike cranks, compatibility is a bit more difficult due to changes in the left crank between versions. If you are unsure, please submit a new ticket with Stages customer support detailing your current bike and crank model. 

Current models (as of Mar 2023):

  • XTR M9100 12-speed: Works only with M9100/9120 cranksets, which do not use a pinch bolt attachment system on the left crank. 
  • XT M8100 12-speed: Works only with M8100, M7100, and similar 12-speed Shimano mountain cranksets that feature two pinch bolts and are 20 mm thick at the BB end. Also works with older XTR pinch bolt style cranks. 
  • Saint: Works with existing Shimano mountain cranksets that feature two pinch bolts and are 25 mm thick at the BB end. Likely option for most 11-speed and 10-speed mountain bike cranks (except XTR).
  • DXR: Works with existing Shimano mountain cranksets that feature two pinch bolts and are 25 mm thick at the BB end. Likely option for most 11-speed and 10-speed mountain bike cranks (except XTR). 


FSA SL-K and Energy BB30 models are interchangeable with other FSA road BB30 cranks, with the exception of any triple crank models. For any 386EVO models, a Stages Carbon or Energy 386 model must be used. Currently, we do not have any compatible models for FSA mountain bike cranks. 


SRAM GXP compatibility is offered for all road cranks through the Stages Carbon for Road GXP model. Likewise, nearly all SRAM mountain GXP cranks are compatible with the Stages Carbon for Mountain GXP models, with the exception of narrow q-factor (156mm) versions of XX and XX1 cranksets. 


The Stages Carbon for 30 mm combined with the appropriate 30mm spindle is compatible with a range of SRAM BB30 crankset options. SRAM BB30 compatibility is limited to SRAM cranksets with the spindle attached to the left side, so older models with the spindle attached to the drive side are not compatible due to this change in design. We recommend consulting our product page for a summary of spindles available and compatible models.


The Stages Carbon for 30 mm power meter is combined with the Stages Spindle G is compatible with most SRAM DUB mountain bike cranks. It is not compatible with DUB variations that use a wider spindle, such as Super Boost and DUB Wide variants. We do not offer a solution for SRAM Road DUB at this time.


The Cannondale Si Hollowgram left crank power meter model is compatible with all current and past generations of Cannondale Si and SiSL2 cranksets. The newest Cannondale Si crank arm uses an integrated self-extracting bolt, which visually differs from past versions, but uses the same thread size and can be installed onto old versions that required a Cannondale crank extraction tool. Older Cannondale SL crank models and cranks from other manufacturers (re-branded Cannondale cranks) are not compatible due to design differences. 

Race Face

Race Face compatibility is limited to Next SL cranksets which utilize a 134 mm spindle, using a combination of Stages Carbon for 30 mm and Spindle E. Other Race Face cranksets using a 134 or 136 mm length 30 mm spindle may also be compatible, but may cause variations in Q-factor/offset on the left crank. 


Campagnolo Record 11, Chorus 11, and H11 left-side power meters can be used on any Campagnolo Ultra-Torque crankset 11-speed or older, with the exception of Super Record. The Campagnolo Super Record left-side power meter is only compatible with Campagnolo Super Record Ultra-Torque cranksets due to the reverse threaded fixing bolt. Super Record 12 is only compatible with 12-speed, while the Super Record 11 power meter can be used with 11-speed or 10-speed Super Record cranksets.  

For all models, 10 and 11-speed cranks can be used with 11-speed versions, while 12-speed versions must be paired with their equivalent 12-speed versions due to the fixing bolt moving to the other side. 

Incompatible brands

We do not currently have a compatible solution for Praxxis or Rotor brand cranksets.
