DT Swiss EXC 1501 Spline One 30 Boost wheelset

The enduro variant of the DT Swiss Spline 1501 Spline One wheelset range, featuring 30 mm full-carbon rims and DT 240 EXP hubs. Very lightweight, from 1701 grams, agile yet extremely stable.

The EXC 1501 SPLINE ONE combines all the features a modern enduro rider could wish for in a wheelset. The 30 mm wide carbon rims offer the precision needed to safely hit even the trickiest lines, whilst a reliable 240 hub with the new RATCHET EXP freehub mechanism transfers pedal power effectively to the trail. The components are held together by high-performance, weight-optimised Competition Race straight-pull

DT Swiss ECX 1501 Spline One 30 straight-pull spokes, with a 35 mm rim width and a weight of just 1609 grams for the wheelset, making it light yet stable enough for freeride and enduro use. Thanks to the high-end 240 EXP hubs with rust-proof ball bearings and the lightweight 30 mm wide carbon rims, the ECX 1501 Spline One wheels offer excellent acceleration. The legendary reliability of the Ratchet System hub and the straight-pull spokes combine to form the perfect competition wheelset.

DT Swiss EXP 240 hubs:

The DT Swiss 1501 wheelset series features the 240 EXP hubs. The DT Swiss 240 EXP straight-pull hubs offer minimal weight combined with exceptional durability. The new axle system, with 15 per cent more support width, increases hub stiffness. The EXP feature on the DT Swiss 240 hubs involves the integration of the pawl and threaded ring, which reduces the number of components and thus lowers the weight. A single cylinder spring ensures faster, complete engagement and therefore greater reliability. The complete interlocking of the spline rings creates a large contact surface and thus low point loads, resulting in superior reliability. The stainless steel ball bearings have proven to be extremely reliable and durable since the introduction of the 240 hubs. The patented freehub body works with spline rings that interlock. This guarantees loss-free power transmission.

DT Swiss Spline One Boost 12x148 rear hub:

The DT Swiss Boost rear hubs feature a wider hub body with spoke lugs and flange positioned further outwards. This makes these wheels even more laterally stiff and durable. Due to the wider hub design with a 148x12 mm thru-axle mount, these hubs cannot be fitted to frames with an X12x142 mm mounting dimension and are only compatible with Boost 12x148 mm and Boost 10x141 mm rear-end frames

DT Swiss EXC 1501 Spline One 30 rims:

Carbon allows for the production of a 30 mm wide rim that provides ideal support for modern tyres, enables lower tyre pressure and thus reduces rolling resistance on rough surfaces. Thanks to the low moment of inertia of a carbon rim, the DT Spline One wheelsets offer rapid acceleration and precise handling. With an internal rim width of 30 mm, they are ideally designed for use from all-mountain to downhill riding with high-volume tyres. The rims of the EXC 1501 wheelsets are extra-reinforced and extremely stable. With an outer rim width of 35 mm, tyres ranging from 2.1 to 3.0 inches in width can be fitted. Thanks to new rim spokes, the DT Swiss Spline One rims are ideally designed for upgrading with a tubeless kit. DT Swiss has also developed new tubeless kits specifically for this purpose. These are included in the scope of delivery

DT Swiss EXP Ratchet Star Freehub Body System:

The EXP Ratchet Star freehub body system uses two ratchet discs, each with 36 teeth. This ensures loss-free power transmission, extreme durability and virtually no play when pedalling. The freehub bodies can be fitted without tools. The freehub bodies are available for classic 8–11-speed HG cassettes from Shimano and SRAM, for the SRAM XD system with SRAM 11- and 12-speed XG cassettes, and for 12-speed Shimano Micro Spline cassettes. The DT Swiss Star Ratchet System enables easy conversion to various axle or rotor standards. The DT Swiss Star Ratchet EXP rear hubs can be easily converted to fit standard mountings: 10x135 quick-release, 10x135 thru-bolt, and 12x142 mm X12 thru-axle mountings. The EXP rear hubs are also compatible with classic endstops, offering a wide range of options for almost all mounting systems.

DT Swiss EX 1501 Straight Pull Spokes:

To achieve an ideal balance between weight and stability, only the highest quality straight pull spokes are used in Spline One wheelsets. They are stiffer than conventional spokes yet can still be trued and replaced using standard tools. The straight-pull lacing allows for precise placement and alignment of the spokes. This optimises wheel stiffness and eliminates any unwanted stress peaks.
