"What Our Gearhead® Experts Are Saying: ""I like this package for riders who want a true XC upgrade that still holds up to today’s rougher courses. The wider front rim gives the Barzo a confident shape for cornering, the slightly narrower rear keeps the Mezcal quick and efficient, and the hubs engage fast enough to stay on top of punchy climbs.""When XC trails turn rocky, rooty, and fast, we want a setup that tracks precisely without costing us energy over long laps. The TR 309/289 XC 29in Boost Wheelset with Vittoria Barzo and Mezcal tires is built as a complete race-and-training system, using a wider front rim for confident steering and a slightly narrower rear to keep the bike feeling efficient when we’re on the gas. From technical climbs to loose corners, this package keeps our lines clean and our effort focused where it counts. The front rim’s 30mm internal width supports the Barzo’s aggressive XC tread for a stable, predictable contact patch when we’re leaning hard or braking late. In the rear, the 28mm internal width helps the Mezcal maintain its fast-rolling feel while still delivering enough bite to climb and brake on mixed terrain. Reynolds’ TSS PR3 carbon construction is tuned for strength and durability, and TR MTN hubs add quick pickup for repeated accelerations. Paired with Vittoria’s Graphene 2. 0 4C compounds and XC-Trail casings, the result is a tubeless-ready system that blends efficiency, grip, and real-world toughness for modern cross-country."
