Can I install a SRAM RED/Force AXS 107 BCD Power Meter Spider on my SRAM Force Wide crankset?

Yes, in most cases you can install the SRAM RED/Force AXS 107 BCD Power Meter Spider on your SRAM Force D1 or D2 Wide crankset as both the power meter and cranks use the same 8-bolt interface. However, before doing so there are some things you will want to know. Let’s break this down…

Force 1x Wide Crankset

Yes, this works just fine. The SRAM RED/Force AXS 107 BCD Power Meter Spider, when ran in a 1x configuration, works perfectly on a Force D1 or D2 wide crankset. Good to go!


Force 2x Wide 43/30 Crankset

So this is where things get a bit more complicated because with the 2x wide 43/30, there is a BCD (bolt chain diameter) mis-match. The SRAM Force Wide crankset uses a 94 BCD for its 43/30 rings, whereas the power meter spider uses a 107 BCD.

Therefore, in order to make it work, you need to install new SRAM 107 BCD chainrings to fit the power meter. SRAM’s smallest 2x chaining that uses a 107 BCD is the SRAM AXS 107 BCD 46/33 Chainrings.

SRAM Force AXS 107 BCD 2x Chainrings – 46/33

So, you can make it work, but you would have to move from 43/30 to 46/33 chainrings.

Technically, the larger 46/33 chainrings aren’t compatible with SRAM rear derailleurs when put on a wide crankset (the largest 2x size SRAM recommends is 43/30). However, we have put the larger 46/33 rings on a wide crankset numerous times without issue. This is referred to as a “kit bash.” That is, something that isn’t officially recommended, but works the majority of the time. If you decide to do this, just know that there exists a small possibility of shifting issues. Again, we’ve never had an issue…but we want to be thorough here.

One way to eliminate any possibility of drivetrain issues is to go to a SRAM AXS 107 BCD 1x Chainring. The 1x chainring, when put on a wide crankset, doesn’t have any issues with the rear derailleur.
