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.
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 2.6″ 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.
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 and Boost hubs are now all centerlock.
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 can be set up with with 11-speed Shimano/SRAM freehub bodies; SRAM XD and XDR Drivers; or Microspline freehubs. Fear not: these are future proof (or at least future resistant)!

Limited Edition 2019 Cyclocross Crusade Mix Tape Disc Asymmetric
Glitz. Glamor. Cyclocross! Crusade!! Glitter!!! The heart of the 2019 cyclocross season is upon us, and that means it’s time for another run of limited edition, custom Cyclocross Crusade wheels. Every year we partner up with the world’s biggest (and dare we say baddest?) cyclocross series to create some special ’cross-crushing wheels. This time it’s all about the shimmery, glimmery, glitter, with a nod to a local favorite team and font that rhymes with Lazers.
The Mix Tape Disc ASYM wheels that these good looks adorn are race-ready cyclocross stompers, but they’re also training strong, gravel road conquerors, and they can even run road tires for your road disc setup. The wheels are the latest iteration of our venerable Mix Tape Discs, updated to a stronger and stiffer alloy, and an asymmetric offset rim profile for more even spoke tension for the 2019 HiFi product lineup.
These wheels are special edition, and only available for a very limited time. And all that extra sexiness can be yours for just $35 over the regular Mix Tape discs. Spin in style!
If you’re local to the PNW, ogle the wheels in person at the main event host booth at the Cyclocross Crusade races all year long (it’s hard to do justice to a sparkle graphic in photos). Or buy em from us online right here.
