Stans Sentry MK3 Rim, 27.5″ 32H

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. 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.
