      Overview

      Control the Adventure

      The G-25 wheels are your go-to to go far. Low on weight and high on reliability, they are the ultimate 650b wheelset for the gravel adventurer.

      Highlights

      • 25mm internal width carbon rim allows you to run wider tires, at lower pressures, for a smoother ride and greater traction
      • Optimized with DT Swiss Aerolite spokes for unparalled aerodynamics and durability.
      • Built with our custom straight pull HollowGram hub shell and reliable sealed cartridge bearings for ease of service and performance
      • At 1450g a pair the G-SL 25 is light without compromising strength
      • Lefty Oliver & 100x12 thru-axle compatible

      Control the Adventure

      Confident Control
      A 650b diameter, 25mm internal rim width, and compatibility with tires 40mm and up. That may sound like a rock-bashing mountain bike wheelset, but on the G-25s, they make a dream adventure gravel wheelset. We’ve built in the durability and strength of a mountain wheel, but kept the lightness and responsiveness of a gravel wheel. The combination makes for all-day fun, no matter where you roll.

      HollowGram SL: No Compromises

      HollowGram SL wheels rise to even higher speeds. Top-shelf DT Swiss Aerolite spokes are paired with custom HollowGram hub shells. Ultra-reliable DT Swiss 240 EXP internals at the rear bring a 36-tooth freehub ratchet for instantaneous pedaling engagement while minimizing mechanical drag. In HollowGram speak, SL means weight is lowered, responsiveness is increased, and efficiency is maximized.
