The Reserve 42/49 700c DT 350 Wheelset is for riders who demand speed in less-than-perfect conditions. The Reserve 42/49 Wheels are more than just fast in a wind tunnel, these wheels are optimized to handle the turbulent cross, side, and headwinds found in real-world riding conditions-providing speed and stability through the least predictable rides. These wheels are aerodynamically optimized through wind tunnel testing and obsessive engineering, to offer every available performance advantage over all-day rides. The combination of a 42mm tall front rim a 49mm tall rear rim, and a slightly wider rim profile up front results in increased stability and control without sacrificing speed. These wheels roll on the legendary DT Swiss 350 hub, an endlessly durable, expertly engineered hub platform that's as fast as it is reliable. Fast, stable, and durable? How about all three?Features Aerodynamically optimized for real-world conditions with stability and predictability in varied wind conditions Lightweight design (at approximately 1429 grams) reduces weight without compromising aerodynamics Taller, narrower rim at the rear for improved aerodynamic efficiency and increased speed Shallower, shorter and wider rim at the front for handling stability and a wider tire footprint DT Swiss 350 hubs feature low rolling resistance, endless durability, and future upgradability Lifetime warranty on Reserve Wheels for ultimate peace-of-mind SPECIFICATIONSWheel Size700c Rim Material Carbon Fiber Inner Rim Width25. 4mm Front, 24. 8mm Rear Rim Depth42mm Front, 49mm Rear Spoke Drilling24Valve Type Presta Tubeless Yes Tire Type Clincher, Tubeless Brake Compatibility Centerlock Disc Front Axle100x12mm Rear Axle142x12mm Intended Use Road, Endurance Road, Road Race, All-Road | Reserve Wheels | Reserve 42/49 Ta Dt 350 700C Wheelset Hg11
