If you're in need of replacement chainrings for your Truvativ Noir or Stylo crankset, look no further than these Truvatic Trushift Chainrings.
They're made from 7050 T-6 aluminum plate, then stamped, coined, and CNC machined into shape. The coining of the teeth is particularly cool because it makes them harder and more durable in addition to the initial intent of shaping the teeth. Truvativ's Powerglide technology ensures fast, consistent shifts with an assemblage of ramps and pins designed to manage the chain better than other systems.
The Truvativ Trushift Chainrings are available as a 32t middle ring and a 44t big ring. Both are Black and fit four-arm spiders with a 104mm BCD.
