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.

Modern XC racers and riders who demand equal uphill to downhill performance, lightweight, durability, and vertical compliance for long hours in the saddle.

Carbon fiber is responsible for unlocking the potential of bigger and wider 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. Compliment increased tire volume and rim width with a modern XC tread, and you’ve got an effective system, maximized for the up and down 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 light weight XC tires with a reduced risk of pinch flatting or impact damage.

For high-traction trail conditions, the upper end of our recommended pressures may not be sufficient. Therefore, we recommend that you increase your tire pressure 5-10% at a time until you find your optimal tire pressure. Examples of high traction conditions would include loam, sandstone/slickrock, tacky flow trails, etc…

If running tires with double ply, triple ply, or DH casings, consider testing the lower range of the recommended tire pressures and move up or down from there until you’ve found your optimal tire pressure.

Front Axle

ENVE supports standard 100mm and boost 110mm front wheel 15mm thru-axle systems on all wheels except the M90 which uses a 20mm front axle. We can convert thru-axles to accommodate quick releases if your fork requires the use of a quick release. Front axle specifications are provided by your fork manufacturer.

Standard = 15mm x 100mm Thru-axle
Boost = 15mm x 110mm Thru-Axle

Rear Axle

Rear axle configuration is determined by your frame. You can find most in the specs section of the manufacturer website.

12x142
The most common current rear axle configuration for all-mountain bikes.
12x148
This is boost. Frames 2015 model year and newer will most likely have a "boost" rear axle configuration.
12x150
Common rear axle on DH bikes model year 2013 and older.
12x157
Most common rear axle configuration on model year 2014 and newer DH bikes.
