I’ve been riding off of cadence for years and have been looking at the upgrade to a power meter. In doing do I am favoring the Stages due to the cost, ease of install, and what appears to be fairly accurate data based on what I have seen compared to Quarq and PowerTap.
I’m not bike mech saavy so here is my quesiton. If I have a BB30 bracket and a Vision crankset, is the non-drive side crank arm interchangeable with any of the Shimano/SRAM (same length) options as long as I am willing to compromise matching crank arms? Or is the design of the Vision crank arm not compatible/matching with the others?
Without having seem a Vision crank set before, I’m going to guess that a Shimano or Sram crank arm is not going to fit on one.
If you are going to be removing the left crank arm, there is nothing hard about pulling the entire thing and swapping it out for a Quarq or other crank based power meter so ease of installation shouldn’t lead you to a Stages power meter. Cost yes, ease of install, no.
No they are not compatible. You are going to have to buy a new crank either way you go.

At which point, you might even want to think about a crank-based PM. At $900 for a complete Stages setup (including a Rival crank), you could spend a little more and get a Power2Max FSA Gossamer with chainrings for $1000. In both cases you’d need to run a BB30-to-something else adapter (either BB30-to-GXP for SRAM or BB30-to-MegaExo for FSA).
Of course, you could get a used Rival crankset and save a bunch of money.
