SRAM offers various options for their Rival AXS, Force AXS, and Red AXS cranksets. There are 16 available variants of the AXS cranksets based on the following combinations;
- 1X vs 2X
- Standard (45mm) vs Wide (47.5mm) chain line
- Power meter
In this article, I’ll summarize all the available crankset models and their differences.
Key takeaways
- Crankarm material. Force and Red AXS crankarms are made of carbon. Rival AXS are made from aluminum with a polished finish.
- Crankarm length. Rival AXS crankarms start from 160mm to 175mm. Force and Red AXS crankarms start from 165mm to 177.5mm.
- Chainring mount. SRAM uses either a Direct Mount (DM), 107 BCD or 94 BCD spider mount, depending on the crankset configuration.
- Wide chain line option (47.5mm) is available for Rival and Force AXS to provide more clearance space for bikes with wider tires. For example, gravel and cyclocross bikes.
- Power meter. Force and Red AXS power meters are spider-based. Rival AXS power meters are crankarm based.
The table below shows the availability of SRAM Rival, Force, and Red AXS cranksets.
