Stages Frame Compatibility Guide

Frame Clearance

You should always check your frame clearance due to the large number of different bike frames. Checking the frame compatibility is simple and can be done with a 10mm Allen wrench.

The diagram below provides the necessary “CLEARANCE ZONE” you need in order to use a Stages power meter.

Chain Stay Brake

If your bike has a chain stay mounted brake that may interfere with the placement of the power meter on the left side, it may still be possible to use the Stages power meter. Please note the following info:

  1. Brake model
  2. Bike model and year
  3. Crank model

Then contact us for a list of potential solutions.

 

Crank Compatibility

Once you’ve checked the frame for clearance, the next step is to confirm compatibility with your existing crank set. In some instances, a left crank option is not available, so a complete crank set may be required. Check our list of models to find an equivalent model with your existing crank. Check the product descriptions to confirm compatibility with other models of cranks from the same manufacturer, as an exact match is not always needed.

To help find your crank model, check the exterior of the crank for any printed brand and model information. The length of the crank is typically engraved or stamped into the back of each crank arm near the pedal spindle.

You can find a large range of compatibility with crank sets from Shimano, FSA, SRAM, Cannondale, and Campagnolo (coming soon).  Though there may not be an exact match for your existing crank, most 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

Stages offers current model left crankset options for DURA-ACE, Ultegra, and 105, and 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. Mountain bike crank interchangeability, however, is limited to cranks XT and below. XTR cranks must be matched up with the equivalent XTR left crank model in either the “race” or “trail” style. Road and mountain bike cranks are not able to be interchanged due to the extreme difference in offset.

FSA

FSA road crank interchangeability depends on the bottom bracket/spindle size utilized by the crank. For this reason, Stages offers models for MegaExo, BB30, and BB386. Models are not able to be mixed between BB30 and BB386 styles, though the attachment is similar.

For MegaExo, compatibility is limited to the current style of crank attachment, which utilizes a single fixing bolt. Older pinch-bolt style cranks and pre-2008 carbon cranks will not work with the current model.

SRAM

SRAM GXP compatibility is offered for all road cranks through the Stages Carbon for Road GXP model. Likewise, 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 crankets. BB30 models offer a range of compatibility based on crankset model and utilize a combination of Stages Carbon for 30mm combined with the appropriate 30mm spindle. 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.

Cannondale

The Cannondale SI left crank power meter model is compatible with current generation Cannondale Si and SiSL2 cranksets. Older Cannondale SL crank models and cranks from other manufacturers (re-branded Cannondale cranks) are not compatible due to design differences.

Race Face

Currently, compatibility with Race Face is limited to Next SL cranksets which utilize a 134mm spindle, using a combination of Stages Carbon for 30mm and Spindle E.
