Description

From gravel adventures to XC exploits, the HiFi Session25 ASYM hookless, asymmetric carbon gravel & mountain bike tubeless-ready clinchers are all about improving your ride experience. The Session25 carbon design makes it easy to hammer on the climbs with the durability needed for re-entry from higher altitudes. The new rim profile measures just over 25mm internal rim width, making it ideal for tires 33mm and up for gravel, or for XC riders and racers looking for a shred-ready lightweight wheel mated to 2.0 to 2.3″ tires. 27.5 rims weigh just 330g, and 29er rims just 350g! And the asymmetric rim profile balances our spoke tensions, making for an even stiffer and stronger wheel build.

  • Fidelity M Disc / Boost Centerlock hubs

More Info

HiFi 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 axle 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!

HiFi disc hubs are now all centerlock, but we do offer some really nifty adapters that let you run 6-bolt rotors with a lockring on our hubs (or any centerlock hub). No bolts required!

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 Shimano/SRAM HG freehub bodies; SRAM XD / XDR Drivers; or Microspline freehubs. Fear not: these are future proof (or at least future resistant)!

All Session wheels are shipped with lockrings, tubeless tape, and valves included, ready to take your existing ride and amplify it.
