Blacklabel 309/289r XC 29in Carbon Boost Wheelset

What Our Gearhead® Experts Are Saying:

"I’ve been racing the 309/289 XC Expert wheels all season. They’re super responsive, hold speed through corners, and the wide profile lets me run lower pressures without squirm. With the SBX hubs engaging at just 4°, I never miss a pedal stroke in techy climbs or sprint finishes."

We race cross-country trails that demand more than just low weight—we want responsiveness, control, and the strength to push hard without holding back. That’s exactly what the Reynolds Blacklabel 309/289 XC Expert delivers. Built with a focus on modern XC performance, this carbon wheelset features differentiated front and rear rim profiles for the ideal blend of compliance and power transfer.

The front rim gives our front tire a broad contact patch and improved damping over rocks and roots, while the rear helps transfer power efficiently on climbs and flats. The Impact Dispersing Matrix (IDM) carbon construction absorbs hits and resists damage better than traditional carbon layups. With lightning-fast 4° engagement from the Ringle SBX hubs, this wheelset feels ready for every start line and every surprise switchback on the course.
