What It Is
A purpose-built XC wheelset without limitations. Light enough to race, strong enough to ride daily. Reduced fatigue and a more compliant ride through shape, laminate, and spoke-hole optimization.
Who It's For
Modern XC racers and riders who demand equal uphill and downhill performance, light weight, durability, and vertical compliance for long hours in the saddle.
Why We Made It
Carbon fiber is responsible for unlocking the potential of bigger and wider tires on mountain bikes. Today, riders can improve comfort, efficiency, and control by adapting their mountain bikes perfectly for the terrain and trails. Undoubtedly, this means they can go further and faster with more confidence. Complement increased tire volumes and rim widths with a modern XC tread, and you've got an effective system, maximized for the variable-pitch trail. The result is a purpose-built full-carbon fiber XC wheelset that is lighter, wider, and more vertically compliant without sacrificing strength or reliability. Additionally, the M525 features ENVE's patent pending, wide hookless beads that improve pinch flat resistance and allow riders to run modern lightweight XC tires with a reduced risk of pinch flatting or impact damage.
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
