Praxis LevaTime 130BCD 53/39 Road Chainring Set – Buzz
SKU code: DSG-PX5339-4022
In Stock
Classic race gearing for 130BCD road cranks. Praxis's cold-forged 53/39 sets use its original LevaTime ramps and pins, with the inner and outer rings timed as a matched pair for clean shifts under load.
Highlights
- Cold-forged 7075-T6 aluminium
- Original LevaTime shifting, designed as a matched set
- Buzz (lightweight) or Aero (solid disc)
- Marked "10/11/12sp" for 10, 11 and 12-speed chains
- Works with 130BCD spider-based power meters such as Power2Max, SRM and Quarq
Buzz or Aero
Buzz is Praxis's lightest ring style, with a more complex finish. Aero is a solid-disc design for aero and TT-style road bikes and is slightly heavier (on a 52/36, Praxis quotes Buzz 158 g and Aero 182 g). Both carry replaceable long and short threaded chain catch pins in the box.
Fitting
Chainring bolts aren't included. Fitting is a separate workshop service and isn't included in the price. Praxis specifies 8-10 Nm for chainring bolts. The Tune workshop can fit the set with the alignment markings and catch pin in the right place, then reset your front derailleur height and limits for the new rings.
Compatibility & fit
- 130BCD road cranks: 5-arm road cranks, and 4-arm cranks with a hidden fifth bolt (such as older SRAM Exogram).
- 130BCD spider-based power meters such as Power2Max, SRM and Quarq.
- Shimano Di2 and mechanical, SRAM eTap/AXS and mechanical, and Campagnolo EPS and mechanical, 10/11/12-speed.
- Not for Campagnolo compact cranks with the proprietary 110/112 hidden-fifth-arm pattern, or Shimano's newer asymmetric 4-arm road cranks.
