Session Carbon MTB Wheels

From slick rock, to East Coast rocks n’ roots, HiFi Session carbon mountain bike tubeless ready clinchers are all about improving your ride experience. At just 1385 grams, the Session carbon design makes it easy to hammer on the climbs with the durability needed for re-entry from higher altitudes.

2019 Updated Session Carbon Rims

New rim profiles mean that we have incredible carbon wheels to cover everything from adventure rides to XC to freeride to Plus. The new Session carbon lineup features rims with a width and depth to match your needs, and stiffness, strength, and overall performance that you can only get with a top notch carbon rim. And ours will blow your mind. Our top XC and gravel adventure wheels, the revamped Session24 hookless rims feature a full 24mm internal width and are 22mm deep. Like all of our wheels, they come tubeless ready to mate up perfectly with your knobbies to provide terrific ride quality, traction, and control. The new Session30 wheels, with a 30mm hookless internal width and 26mm depth, is the all-around most popular for freeride and general MTB use. And the Session35 at a hookless internal width of 35mm is perfectly suited to Plus tires in the 2.8″ to 3.0″ range, and runs a whopping 29mm deep.

Whether 27.5 or 29er, the Sessions are shipped with tubeless tape applied, ready to take your existing ride and amplify it.

2019 Updated MTB Hubs

HiFi know offers a MTB-specific disc hub, both in Boost and regular 100mm / 142mm spacing (or 135mm for those QR holdouts out there). The Fidelity M Disc centerlock has regular disc spacing, while the Fidelity Boost takes care of the wider needs. The rear hub has 6 offset pawls with two engagement points each, and they interact with a ring that sports 102 teeth. That translates to an engagement angle of less than 2 degrees — lightning quick!

Fidelity M Disc hubs are now all centerlock. Boost hubs are currently available in both centerlock and 6-bolt. Please confirm Boost inventory and your preference when ordering.

Some Future Proofing and Built-in Flexibility

Any of the Session wheels can be built around our Fidelity Boost hubs (110mm front, 148mm rear). And for those running non-Boost setups, the Fidelity M Disc front hub quickly converts to 15mm or 12mm thru-axle, or to quick release, and the rear hub converts to a 142×12 or 135mm QR. End caps to match your preferred setup are included with all of our MTB wheels. All of our HiFi Fidelity Disc hubs come with 11-speed Shimano/SRAM freehub bodies, and a spacer for those running 9 or 10 speeds. SRAM XD and XDR Driver freehubs are also available. Fear not: these are future proof (or at least future resistant)!
