Heavy duty and extra wide PVC rim strips for maximum tube protection.

Replacement end caps for Stan's NoTubes rear hubs with XD Driver.

Stan's Enduro Rim Strip converts standard tubed wheels to tubeless so you can reap the benefits. Going tubeless allows you to run low tire pressure for better traction while drastically reducing the chances of a flat. Stan's rim strips create a tight seal with the tire bead, reducing the instances of "burping". Plus, you won't miss dealing with flat tires and you'll save money on tubes!

Stan’s S1 wheelset line brings patented tubeless technology to an even wider range of riders. Built for long life, low maintenance, and outstanding value, the S1 series wheels feature 6061 series alloy rims and are available in six different widths suited to a wide range of tire sizes and riding styles. With an emphasis on value and durability, the S1 alloy wheelsets join a mountain wheel line-up that currently includes Stan’s successful MK3 premium alloy wheels and innovative Valor and Bravo carbon series wheelsets. While MK3 wheelsets are built to balance strength, light weight, and stiffness, S1 wheelsets focus on maximum strength and durability. The deeper profile and thicker walls of the S1 rims result in a 50-70g weight increase over MK3 rims, but offer greater impact strength for an even wider range of use. “The new S1 series wheels were developed from rims ridden in Redbull Rampage and raced on the World Cup DH circuit for years,” said Creative Director, Chris Currie. “The goal was to take everything we’ve done for tubeless technology, and put it into a truly bombproof and affordable wheel.” Designed according to Stan’s WideRight rim and tire fit system, S1 series wheelsets are available in six different rim models, with internal widths ranging from 23mm to 38mm. Combined with Stan’s low-profile, high-volume Bead Socket Technology rim design, these widths let the new S1 range accommodate tires from 2-inch to 3.5-inch. All S1 wheelsets are built with 32 spokes front and rear, Sapim’s proven Race spokes, Secure Lock brass nipples, and Stan’s faster-engaging Neo hubs. Hubs are available to fit most axle systems, including Boost. The S1 series includes reinforced versions of the classic Crest, Arch, and Flow--names already familiar to fans of Stan’s tubeless rims. In addition to the Crest S1, Arch S1, and Flow S1, three entirely new wider wheelsets will be available. The Sentry S1, Baron S1, and Major S1 bring Stan’s patented Bead Socket Technology to Plus bikes. Flow S1 Wheelset - Use: Aggressive Trail, All Mountain, Enduro, and Downhill - Internal Rim Width: 29mm - Optimal Tires Size: 2.35 to 2.8-inch - Hubs: Stan’s Neo 32-hole Front, 32-hole Rear - Spokes/Nipples: Sapim Race Black 2.0/1.8/2.0mm, Secure Lock Brass Silver Nipples - Wheel Sizes and Weights: 27.5-inch (2,034g), and 29-inch (2,134g)
