Rims

Designed for today's wider tires, the Sentry MK3's patented low-profile sidewall and lightweight 6069 alloy construction deliver width without the weight. Stan's 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. The Sentry MK3 proves wider can mean faster. - More stable 32mm internal width for tires up to 3.0" - Gradual taper rim shape and 6069 alloy is lighter, stiffer, and stronger - Patented BST design for easiest and most reliable tubeless - Most trusted tubeless system for easy setup and low maintenance - Sapim Secure Lock aluminum nipples - WideRight optimized for 2.50"-3.00" Trail tires
