Pair of Fulcrum Wind 42 DB carbon wheels; rim height 42 mm and internal width 23 mm. Shimano freehub. The internal rim bed has no holes and allows for a native 2-WAY FIT™ Tubeless rim, without the need for any rim tape, so they can be used with both inner tubes and tubeless (with never-used valve that I provide). As visible in the photos, the wheels are brand new. Included: Two Way Fit tubeless valves and user manual.
