TR 309/289 XC 29in Boost Wheelset/Vittoria Tire Set

What Our Gearhead® Experts Are Saying:

"This is a smart cross-country pairing because the wheel widths match what the tires want. The Barzo benefits from the wider front rim for support in corners, the Mezcal stays quick on the slightly narrower rear, and the carbon build holds up well when courses get rough."

Modern cross-country racing demands equipment that manages traction, efficiency, and impact resistance on increasingly technical terrain. The TR 309/289 XC 29in Boost Wheelset with Vittoria Barzo and Mezcal tires is a matched system designed to improve steering precision up front while keeping the rear wheel efficient and comfortable under sustained effort.

Reynolds uses TSS PR3 carbon construction to increase rim strength and durability for both racing and high-mileage training. The asymmetric design approach is paired here with a wider 30mm internal front rim and a 28mm internal rear rim, supporting modern tire profiles while maintaining responsive handling. The lower-profile rim shape contributes to precise tracking, and TR MTN hubs provide quick engagement through a 3-pawl, 10-degree mechanism for repeated accelerations and technical climbing.

The included Vittoria tires complement the wheelset’s intent: the Barzo provides a more aggressive XC tread for cornering confidence and braking control, while the Mezcal uses a densely packed, low-profile knob layout to reduce rolling resistance without sacrificing usable grip. Both use Graphene 2.0 4C compounds and XC-Trail casing designs with tubeless-ready beads, making this package best suited for riders targeting technical XC, marathon racing, and fast trail riding where efficiency and traction must coexist.
