The wheelset featuring DT Swiss 350 Spline straight-pull hubs and the lightweight yet sturdy DT Swiss RR 421 rims. Hand-built in our specialist workshop. You can customise this wheelset entirely to your specifications. Thanks to their 20 mm rim width, the RR 421 rims are suitable for tyres between 28 and 40 mm wide. Combined with the DT Swiss Straightpull hubs from the 350 series, you get a fast and lightweight wheelset with real durability

Wheel building at TNC-Hamburg:

We manufacture these wheels entirely by hand for you. Thanks to over 30 years’ experience in wheel building, we extract the optimum in roundness, durability and stiffness from the materials. These wheels are, of course, tested multiple times; we also pre-load the spokes in both the radial and lateral directions. This eliminates the need for re-truing over a long period. We use DT Swiss spokes exclusively. These ensure outstanding durability of the wheelsets. For DH and Enduro use, we recommend brass nipples.

These wheels are custom-made for you, so we cannot offer a right of return for them. Please feel free to enquire about other wheel configurations. We will then send you a quote.

DT Swiss 350 Disc hubs:

The new DT 350 Classic hubs feature the new Ratchet SL freehub body system with 36 teeth. With the 350 hubs, DT Swiss offers affordable, high-quality hubs. From road bike to downhill versions, the 350 hub range is designed for maximum durability. Fitted with high-quality seals and bearings, they are the ideal choice if you are looking for hubs for durable, low-maintenance wheelsets. The DT 350 rear hubs are also fitted with DT’s patented Ratchet freehub body system. Two toothed discs mesh together to guarantee loss-free power transmission. Thanks to the raised hub flanges, the DT Swiss 350 hubs provide wheelsets with excellent lateral stiffness and durability.

DT Swiss RR 421 rim:

The DT Swiss RR 421 DB road, gravel, cross and touring rim, designed for use with disc brakes, is very light at just 420 grams and sturdy thanks to its high-strength aluminium alloy and 24 mm rim width. With a 20 mm rim width, the DT Swiss RR 421 DB rim is ideal for tyre sizes ranging from 28 to 40 mm. The rim’s asymmetrical design allows for more even spoke tension, significantly increasing stability and service life. Cleanly finished, with a welded joint, CNC-machined sidewalls and a 21 mm deep rim bed, the DT Swiss RR 421 DB is the ideal rim for building very lightweight wheelsets.

The DT Swiss RR 421 DB rims are high-end rims with a special spoke nipple mount and are supplied with special DT Squorx Pro Head nipples and PHR washers; they must only be laced using these nipples. Furthermore, the DT RR 412 rims are tubeless-ready.

DT Competition spokes:

These double cold-forged spokes are made from rust-resistant 18/10 chrome-nickel steel with a tapered mid-section for robust, lightweight wheelsets. We recommend these spokes for virtually all wheelsets. Extremely durable and sufficiently lightweight, DT Competition spokes enable wheel building of the highest standard. Thanks to the tapered centre section, the spokes absorb movements in the wheel exceptionally well, without compromising on lateral stiffness or durability. Weight with nipple approx. 7 grams.

DT Competition Race spokes:

Just as versatile as the bent version of the DT Competition spoke, but as a straight spoke. They are optimally matched to the new straight-pull hubs and offer even greater durability compared to the conventional DT Competition spoke. Thanks to the extra-thin middle section, they save a further 35 g per wheel compared to the already lightweight DT Competition, whilst offering almost the same stiffness and durability.

DT Swiss Aero Comp spokes:

Designed for stable, laterally stiff yet aerodynamic wheelsets, the DT Swiss Aero Comp spoke is cold-forged in the middle section, making it lighter and stronger. In a further complex process, it is flat-forged to optimise aerodynamic properties whilst simultaneously increasing material strength. The DT Aero Comp guarantees a balanced ratio of stiffness, aerodynamics and durability.

DT Swiss Aero Lite spokes:

The DT Swiss Aerolite spoke is flatter and lighter than any other; the DT Swiss Aerolite spoke features an aerodynamic flat profile and is extremely lightweight. Thanks to the 0.9 x 2.3 mm aerodynamic mid-section, this spoke can be fitted to all standard hubs. The Cold Forging Technology (CFT) developed by DT Swiss makes the reduced and forged DT Aerolite the lightest stainless steel spoke and gives it excellent mechanical properties. Particularly suitable for super-light and fast road or cross-country wheelsets. 64 DT Aerolite spokes weigh an incredible 278 g at a length of 264 mm. Weight per spoke at 264 mm length: 4.31 grams

DT Swiss Revolite spokes:

The DT Revolite is the ideal choice for riders looking for a spoke that combines durability, low weight and aerodynamics. With a 2.3 x 1.3 mm cross-section in the middle section of the spokes, these offer excellent aerodynamics. Through several rounds of development, their innovative shape has been optimised to outperform all other DT Swiss MTB spokes in their weight class in terms of durability. This has been achieved through the unique blading process, which achieves additional densification of the material, and a patent-pending process that ensures a uniform transition from the tapered to the forged section of the spoke. Weighing just approx. 4.5 grams at a length of 264 mm per spoke, the Revolite is also exceptionally light.

DT Squorx spoke nipples:

The DT Swiss Squorx Pro Head nipple combines ease of installation with light weight thanks to the DT Pro Head shape, combined with an additional Torx and square tool socket. The Torx socket provides a larger contact area during wheel building, ensuring that the force from the tool is better distributed across the nipple. The spherical contact area within the rim guarantees perfect alignment with the spoke.
