Leonardi is the Italian brand specializing in drivetrains and components for your bike, and you can now find it atEscapa. Thelightweight, rigid,oval Leonardi Track 76 XX1 Chainringfor SRAM XX1 Spider is compatible with Leonardi Racing’s 76 mm bolt circle. These chainrings bolt onto the crank spider, allowing for a quick change to a different chainring pitch, as well as an optimal setup for single-speed or 1x10/11 drivetrains.
The 7075 T6 aluminum alloy used ensures low weight and reduced wear. The specially designed narrow-and-wide teeth effectively prevent the chain from skipping. The design follows that of SRAM XX1 chainrings. When combined with an SRAM Type 2/3 or Shimano Shadow+ derailleur—which has significantly greater cage preload—the chain remains reliably in position even without a chain guide.
The chain’s oval shape enhances performance by varying the gear ratio and optimizing resistance. When pedaling, the natural strengths and weaknesses of the legs are balanced. This results in better utilization of the stronger muscle groups, while the weaker muscles are compensated for in the work cycle (shorter stroke).
