Santa Cruz Hightower 4 Carbon C 29" 90 Kit Mountain Bike 2026

Big on wheels, short on fuss, this is the pinnacle of go-anywhere-anytime bikes. A balance of travel, wheel size and attitude makes this a true MTB for modern mountain biking. Whether that includes the rarefied air of the alpine or just local trailheads, built and burly trails or sublime natural singletrack, the Hightower is an all-terrain thriller.
