Chainring swaps on AXS cranksets require matching the bolt pattern and tooth interface to SRAM's X-SYNC specifications. The Rival AXS E1 2x Chainring Kit provides both rings for a complete replacement, using the 8-bolt direct mount pattern that fits Rival, Force, and Red AXS road cranks. The tooth profiles maintain the same chain retention geometry as the original rings, keeping shifts crisp across the full cassette range.

The kit ships in two configurations: 46/33T for tighter gear spacing or 48/35T for a more traditional road setup. Both options use the same mounting interface and work with any SRAM 12-speed Flattop chain. The inner ring attaches to the spider with four bolts, while the outer ring uses four separate mounting points, allowing individual replacement if you wear one ring faster than the other down the road.

Material construction matches what SRAM specs on complete Rival cranksets. The rings use forged aluminum with a machined tooth profile, providing a balance between weight and durability that suits the Rival tier's positioning. Shift ramps and pins are CNC-machined into the ring faces, timing chain movement during front derailleur shifts.... Read More
