Gravel riding puts a wheel through chatter and rutted surfaces that pavement never does, and the Revive 2. 0 Solix Carbon Wheel is built with that instability in mind. A 25mm internal width and 19mm rim depth keep the wheel stiff enough to hold a line through rough terrain, while the Solix hub's 0. 59-degree pickup keeps power moving the instant the surface gets unpredictable. What Our Gearhead(R) Experts Are Saying:"I hit a rutted-out fire road at speed expecting to get bounced off my line, and the wheel held true through every rut instead of skipping sideways."
