With patent pending Wave™ retention technology.  Licensed and developed in conjunction with MRP. 

The Wave™ pattern applies alternating lateral force to each chain link to actively retain links to ring – going beyond narrow/wide implementation that relies solely on friction.  The Wave™ tooth pattern swings right to left, grasping the interior of the chain for retention, but allowing room for mud, debris, and grit to escape. The Wave™ design creates more open areas for mud and debris evacuation and preserves chain retention in adverse conditions – one of many “Achilles’ Heels” of narrow/wide designs. Designed with mindful consideration of system friction, the Wave™ design actively engages the chain but yields much less concentrated wear than competing designs — spreading the load over large surface areas instead. Tough enough for Enduro, Downhill, and also weight conscious for XC riding. These MTB Wave Tech rings are machined from 7075-T6 aluminum and Hard Anodized to take a beating.

Specification:

The Wave™ tooth pattern swings right to left alternating lateral force to each chain link to actively retain the chain.  This design creates more open areas for mud and debris evacuation and preserves chain retention in adverse conditions.

  • Direct Mount – For Praxis Direct Mount MTB cranks or 3-Bolt SRAM style interface. 
  • 26, 28, 30, 32, 34, 36T  –  Please see photo guide for DM-A/DM-B chain lines.
  • New Wave Technology tooth profile.  Alternating teeth for better chain retention.
  • 10/11sp Shimano/KMC/SRAM, 11sp SRAM XX1 chain
  • 7075-T6 Al for superior stiffness
  • Stamped and machined manufacturing with hard black anodizing for durability
  • REAR DER- Must use a 'CLUTCH' type rear derailleur. Example Shimano Shadow or SRAM Type 2
  • In very rough terrain, or just for pure security, we still recommend use of an upper guide

    Compatibility:

    • For Praxis Direct Mount MTB cranks or 3-Bolt SRAM style interface. 
    • RD- Must use with Mid or Long cage 'CLUTCH' type rear derailleur. Example Shimano Shadow or SRAM Type 2
    • In very rough terrain, or just for pure security, we still recommend use of an upper guide 

    Warranty: 

    Praxis Works warrants components to be free from defects in materials or workmanship for a period of 2 years after original purchase. However, there are limitations as “nothing lasts forever”
