Enve M525 Carbon Mountain Rim


The latest generation of Enve's M-Series carbon mountain rims address a critical concern of riders: the possibility of expensive damage from the heavy impacts that inevitably occur when riding off road. The rims across this new series feature wide hookless tire beads to increase the load area from impacts, significantly reducing the possibility of pinching a tubeless tire or cracking a rim. Enve's confidence in their design is apparent in their industry-leading 5 year "no hassle" warranty policy that explicitly covers damage from impacts. This system allows riders to roll with confidence and choose lighter, faster tires for improved speed and performance.

The M525 rim is Enve's flagship XC racing rim, lightweight and nimble for maximum speed on cross country style courses, yet strong enough for daily riding. Relative to the other M-Series rims, the 525 is shallow for increased compliance and reduced weight, with a 25mm internal bead width optimized for 2.1-2.3" wide tires. As with every rim Enve has ever built, these rims are designed for internal nipples with spoke holes that are molded and not drilled for the best possible strength and long-term durability. Enve's corrosion-resistant self-locking brass nipples are included. The rim bead features an ultra-reliable tubeless ready design, and each rim purchase includes a full tubeless kit with tape and valves. M525 rims are available in 24 hole only for the lightest possible complete wheels.


Enve M-Series rims are guaranteed to be free from defects in materials or workmanship for five years from the original purchase date. Rest assured that Enve will cover impact damage from riding.
