DT Swiss All Mountain Wheels DT Swiss have designed the XM1700 SPLINE wheels to be the best all mountain wheels, but you decide. DT Swiss have given everything needed to dominate the mountain. These wheels are light and robust with welded rims, and perfect tubeless compatibility. The reliable 350SL hubs, with their Ratchet freehub and the 36 tooth engagement, are a joy to ride. Equipped with the XM1700 SPLINE wheels nothing can stop you from your personal all mountain adventure. Light and Strong Rims DT Swiss have chosen to build a quality set of alloy rims into a quality wheel set known and valued for their low weight, high quality and strength. Welded top notch alloy rims, and in combination with DT Swiss’ unique PHR nipple-spoke interface washer which distributes the load on a large area, they have been able to reduce the wall thickness while keeping the rotational mass low. Lighter, Great Power Transmission The DT Swiss 350 Hub rear hub is equipped with the DT Swiss very successful Ratchet System. What makes the Ratchet System hubs truly unique is that all the teeth of the two ratchets engage simultaneously and create a large contact surface to transmit huge torque. The result is an amazing reliable, fast engagement Ratchet System. Thanks to the no-tool concept, the hub is easy to maintain and the freehub body can be converted without the use of any tools. For the new MX1700 SPLINE® the 350 was upgraded with a 36T Ratchet SL system (SL stands for super lightweight). This is the ultimate in terms of reliability, weight saving and power transmission. Reliable Spokes Always Wheel builders have trusted DT Swiss spokes for decades. DT Swiss has a long experience in producing light and resilient spokes. Their competition spoke is one of the most versatile spokes in the DT Swiss spoke range. DT Competition® has a unique processing which results in a spoke with a slim butted section for low weight and a strong head and thread for durability.
