Designed for today’s wider tires, the Sentry MK3’s patented low-profile sidewall and lightweight 6069 alloy construction delivers width without the weight. Our patented BST rim design allows a tire to expand to its full volume without distorting its shape, and the 32mm internal width of the Sentry MK3 is more stable with 2.50”-3.00” tires. The result is less rolling resistance, more traction, and incredible handling. The Sentry MK3 wheelset is a great upgrade for anyone looking for the traction and control needed to take on even the most difficult trails. Our updated Neo hub includes a stronger axle and reliable Durasync six pawl freehubs. Offered in 26”, 27.5” and 29”, with the option to purchases as a wheel or a rim, the Sentry MK3 proves wider can mean faster.
