White Rose Engineering offers main gear wheels from 3.5" to 4.7s" in diameter. These wheels are available in five different spoke patterns. The wheels are as light as, or lighter then comparable sized Du Bro or Sullivan wheels. The tires are captured with almost 3/8" of rim inset so they do not roll off the hubs. All White Rose Engineering's wheels are engineered to exactly fit their titanium axles which feature "C" clips for wheel retention and up to three lateral positions for wheel pant centering.
