In a constantly evolving industry, bicycle component manufacturers sometimes stumble upon a brilliant concept through simple repurposing of an existing product. The M525 is a prime example of this. Originally intended for use on lightweight cross country mountain bikes, some experimentation showed that these rims are equally worthy for use on drop bar, disc brake gravel bikes. Following thorough testing with narrower gravel-pedigree tires, Enve simply re-dubbed the M525 as the M525 G, clearing these for use on 650b and 700c adventure machines. It's the same rim, just with a different mission.
Enve's M-series 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.
Within Enve's gravel rim lineup, the M525 G is the heaviest-duty rim. This rim is an excellent option for stronger and/or heavier riders, or for rougher courses that require larger tires. The 25mm internal bead width accommodates tires as narrow as 32mm. 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 G 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.
