Nowadays, bikers ride what used to be called downhill trails on enduro bikes. The trails are getting rougher, and the demands on the gear and rider are greater. The E 1900 SPLINE has been developed to deal with precisely these requirements. With its stiff aluminum rim, lightweight straight-pull spokes, and proven DT Swiss hubs, this wheel is well-prepared for any challenge. The balance of weight and stiffness will put a smile on your face whether you're riding uphill or downhill. After all, most of the best trails don't offer lift service.

Mountain bikes are becoming longer, slacker, and faster. The M 1900 SPLINE 30 is our answer to these developments. The rim is very durable and offers a 30mm rim width, which eliminates tubeless tire burping and allows you to reduce the tire pressure to keep you in greater control. Twenty-eight cold-forged spokes tension the rim in a DT Swiss straight pull hub to provide the ultimate balance of light weight and stiffness. No matter how steep or how rocky your trail, the M 1900 SPLINE is more than up to the challenge.

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.
