TIRES
Is this wheel right for you?
BEST FOR
Gravel riders who want a light wheel without giving up strength
Long, hard gravel days with a lot of climbing
Running high-volume tires (36mm to 55mm) at lower pressures
Replacing heavier OEM or Alloy Gravel Wheels
Mixed terrain: gravel roads, rough doubletrack, and the occasional stretch of singletrack
NOT IDEAL FOR
Road riding on tires narrower than 36mm (see the 36 Road Disc SL)
Gravel racers who want an aero rim profile (see Pinnacle Race)
Riders whose gravel regularly looks like mountain biking and who want maximum toughness over minimum weight (see Reiver)
How We Got to 1145g Without Giving Up Strength
1 - Performance Targets First
Impact resistance, stiffness, and fatigue life locked in before any weight comes out.
2 - Rim architecture
A 25mm deep, 26mm wide hookless profile shaped for high-volume tires at low pressure. The offset rim bed evens out spoke tension for a stronger wheel that stays true.
3 - Carbon layup strategy
Aerospace-grade carbon placed where gravel impacts actually land, not spread evenly just to hit a number. The result is a 322g rim.
4 - Dimensional control + QC
Bead seat, ERD, and critical interfaces inspected so every build starts true.
5 - Spoke & Tension Plan
Pillar Wing 20 spokes, 24 front and rear, chosen for long-term stability and easy service, not the lightest spec sheet.
6 - Handbuilt, stress-relieved
Multiple tension cycles, stress relief, and final balance checks. Stays true on rough roads.
Carbon Rims
Every cut and ply of carbon plays a story in how a rim responds. Aerospace grade carbon is used in strategic places for increased strength with bringing the rim weight down to just 322 grams
Grade 54 Hubs
The new Grade 54 hubs are the most advanced hubs we've ever created. Weighing just 270 grams for the set, the hubs feature a ratchet drive system with 54 teeth and just 6.6 degrees of engagement
Enduro Bearings
The Enduro ABEC 5 bearings provide exceptional precision and durability, ensuring that the hub operates smoothly under the most demanding conditions.
Handbuilt
Every wheel goes through 5 different work centers, before being QCed for true, run out, and spoke tension. This ensures every wheel will keep running as true as the day you received them.
BEHIND THE NAME: JOCASSEE
Jocassee (Joe-Cass-EE) is a heritage preserve in the Northwest corner of South Carolina. Containing over 100 miles of gravel roads, Jocassee is a favorite of cyclists looking for a very difficult gravel ride. Founder, Boyd Johnson, started riding in Jocassee on a road bike with 25mm tires in the early 2010s (not highly recommended at all!). Over time gravel started to emerge as a discipline, people migrated to cyclocross bikes, followed by gravel specific bikes.
