The WTB Macro 54 is the high-volume, rough-terrain option in WTB&';s new gravel family. Its wider casing and more aggressive tread add confidence on loose, rocky, and technical surfaces, while the relatively low center tread keeps it moving efficiently on hardpack. Wider-spaced transition and shoulder knobs give the tire a clear step up in cornering traction for bigger gravel rides and rougher routes. The Macro uses a supple 120 TPI TCS Light casing, Dual DNA rubber, and SG2 bead-to-bead puncture protection. Patent-pending trip strips and vortex generators developed with Stromm manage airflow around the wheel-and-tire system to help reduce drag at higher speeds. The profile is optimized around a 28 mm internal rim, with a recommended range of 25-31 mm.
