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. Baron S1 Wheelset - Use: Plus Tire Performance, Adventure, and Trail - Internal Rim Width: 35mm - Optimal Tire Size: 2.8 to 3.2-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: 26-inch (1,998g), 27.5-inch (2,060g), and 29-inch (2,162g)

Wider and even lower profile, the new Crest MK3 sheds weight for faster acceleration and climbing. WideRight 23mm internal width increases tire volume for improved stability with wider tires. Inspired by Stan's carbon technology, the entirely new rim shape adds strength and virtually eliminates the chance of a tire pinch flat. Refined over the past 15 years, Stan's Bead Socket Technology offers the most trusted tubeless seal in the business, making the Crest MK3 the best choice for lightweight, tubeless XC performance. - Tubeless ready with rim tape and valves installed - 23mm internal rim width for more stability with larger tires - Low-profile shape rolls faster, lasts longer, and helps stop tire pinch flats - Laterally stiffer and stronger for improved handling - Wider but even lighter than the original Crest - More durable rim shape and alloy Neo hubs accelerate quicker and last longer - Most trusted tubeless system for easy setup and low maintenance - Legendary Crest climbing and speed in a high volume rim - WideRight optimized for 2.00"-2.25" XC tires

The new standard for durability and price. - Patented Star-Ratchet system - Contact-free seals and high precision build guarantee smooth bearings - Press-fit end caps allow tool-free maintenance and conversion

Reliability meets simplicity—running smoothly day-in and day-out. The 350 hub was developed according to the credo: Reliability meets simplicity. The simultaneous engagement of the ratchets and the resulting large engagement area provides the reliability. The plugged construction allows easy maintenance without the need for tools. Adaptation to different axle standards or modification of the engagement angle is also possible with just a few manual steps.
