Stans NoTubes Sentry MK3 Rim

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 27.5” and 29”, the Sentry MK3 proves wider can mean faster.
