SRAM XX1 NARROW WIDE 11 Speed Single Chainring 4 Arms 76 mm

The SRAM XX1 components are designed around the single chainwheel philosophy: Simple, lightweight and effective
A single chainwheel (available in various teeth sets), 11 speeds on a 10/42 cassette: all you need to ride anywhere in either XC or Enduro.

Single X-Sync chainring with revolutionary teeth allowing you to do without a chain guide. They are machined specifically to better retain and guide the chain.
The star also has a special design allowing you to easily switch chainrings without disassembling the chainset. This allows you to adapt the teeth according to the terrain and plan for the day.
