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.
Will mount to most any 4-arm 104BCD MTB crank
30T is a threaded ring and needs M8 male bolt with min 7.5mm length for 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. Howe'ver, there are limitations as nothing lasts forever so please read our Warranty page for details.Specification
