Swap gearing on a Praxis road crank without replacing the spider. X-Rings mount to the Praxis X-Spider, and because every Praxis X-Ring set shares its 4-bolt 160/104BCD pattern, anything from 48/32 to 53/39 fits the same spider.

Highlights

  • Made for the Praxis X-Spider's 4-bolt 160/104BCD pattern
  • Forged 7075-T6 aluminium, hard anodised
  • LevaTime II sets: stiffer 5 mm big ring and forged shift pins for quicker shifts
  • Sport sets: the economy tier in 48/32, 50/34 or 52/36
  • Inner and outer rings designed and timed as a matched set

LevaTime II

For LT2, Praxis moved the big ring to a thicker 5 mm plate so it could forge in more shift features, plus new fast-engaging forged shift pins. Praxis says its X-Rings shift well with Shimano, SRAM and Campagnolo 10/11/12-speed chains and drivetrains.

Check the 12-speed marking

Praxis marks its 12-speed-compatible LT2 rings "10/11/12sp" on the big ring and notes that earlier production marked "10/11sp" is not 12-speed compatible. If you run 12-speed, ask us to confirm the marking on the set you're ordering.

Fitting

Fitting is a separate workshop service and isn't included in the price. X-Rings mount to the spider with M8 male threaded chainring bolts (Praxis's X-Ring 2x bolt kit is 8 bolts, torqued to 8-10 Nm). The Tune workshop can swap the rings, reset your front derailleur for the new sizes and torque everything to spec.

Compatibility & fit

  • Praxis X-Spider only: Praxis 3-bolt direct mount road cranks fitted with an X-Spider, or the spider from a LevaTime II X-Kit.
  • Not for 5-arm 110BCD or 130BCD spiders; see Praxis's Buzz, Buzz Sport and Aero sets for those.
  • Shimano, SRAM and Campagnolo 10/11/12-speed on rings marked "10/11/12sp".
