Small ring wear is easy to miss until it isn't. You notice the front shifts feel sluggish, the chain slaps down onto the inner ring instead of settling cleanly, and every hard downshift into the climbing gear becomes a small gamble on whether the chain drops or hangs. When the teeth on your inner ring start looking hooked or shark-finned, replacing just the small ring — instead of the whole crankset — brings shifting back to spec for a fraction of the cost. SRAM's Powerglide 10-Speed Inner Chainring is the factory replacement for Force, Rival, and Apex 10-speed road cranksets.

Powerglide chainring technology starts with raw 7075-T6 alloy plate that SRAM stamps, coins, and CNC machines into the finished ring, with the coining process shaping tooth profiles into designs CNC alone can't match and strain-hardening the alloy for durability. That matters more on the inner ring than most riders realize — the small ring sees the highest chain loads when you're grinding out of the saddle on a climb, and softer aluminum wears into hooked profiles faster than a properly hardened ring. The hard-anodized black finish adds corrosion resistance and keeps the ring looking consistent with the rest of your 10-speed groupset.

Compatibility runs across SRAM's 10-speed road platform. These rings fit SRAM Force 2012, Rival, and Apex, and are also compatible with SRAM Red Black Edition and Force 2013, but are not compatible with the SRAM RED Exogram crankset. The 110 BCD versions cover compact and mid-compact pairings (34T with a 50T outer, 36T with a 50T or 52T outer), while the 130 BCD 39T is the standard racing inner paired with a 53T outer. Match the BCD to your existing crankset spider and you're set.... Read More
