Stans 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 Stans 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 weve done for tubeless technology, and put it into a truly bombproof and affordable wheel.

Designed according to Stans 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 Stans 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, Sapims proven Race spokes, Secure Lock brass nipples, and Stans 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 Stans 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 Stans patented Bead Socket Technology to Plus bikes.
