The Reserve 37 Zipp 76/176 Carbon Rear Wheel is built for riders who prize agility, acceleration, and control. Designed around a mid-shallow 37 mm rim and paired with Zipp’s time-tested 176 rear hub, it’s a wheel that delivers effortless climbing response, confident stability, and the unmistakable smoothness that defines Reserve’s carbon craftsmanship. Light enough for steep ascents yet strong enough for high-torque sprints, it’s a pure expression of efficiency and handling refinement.

Reserve’s proprietary carbon lay-up provides the ideal mix of lateral stiffness and vertical compliance, translating power directly into motion without sacrificing ride comfort. The 37 mm depth strikes the perfect balance between reduced rotational mass and aerodynamic benefit — shallow enough to stay stable in gusty conditions, yet deep enough to maintain momentum on rolling terrain. The 21 mm internal width is optimized for 25–30 mm tires, improving cornering grip, lowering rolling resistance, and enhancing ride quality across imperfect pavement. Tubeless-ready and hookless by design, the rim simplifies setup while allowing lower tire pressures for better compliance and traction.

At its core, the Zipp 176 hub ensures consistent, dependable performance. Built with sealed cartridge bearings and a lightweight alloy shell, it spins smoothly through countless hours of training and racing. The freehub’s reliable pawl mechanism engages quickly and evenly under power, converting every watt into clean acceleration. Optimized flange geometry improves spoke bracing angles for better stiffness and long-term durability, making it a low-maintenance, high-efficiency centerpiece for this versatile rear wheel.

Each wheel is hand-built using Sapim CX-Ray bladed spokes in a two-cross pattern, balancing aerodynamic performance with tensile strength. The asymmetric spoke drilling ensures even tension between drive and non-drive sides, maintaining perfect alignment under load. Reserve’s precise assembly and tension-checking process guarantee durability and straightness for the long haul. The result is a wheel that feels responsive when you dig deep, yet refined and composed during long days in the saddle.

From twisting mountain roads to long stretches of fast tarmac, the Reserve 37 Zipp 76/176 Rear Wheel delivers that signature mix of lightness, stiffness, and balance. It accelerates instantly, holds its line through wind and corner, and stays true season after season. For riders seeking a carbon rear wheel that climbs, sprints, and endures — this is Reserve’s most versatile expression of speed and simplicity.
