Schmidt Son 28 hub dynamo wheel with DT Swiss RR411 rim

The 28-inch front wheel with the Son 28 dynamo and Boost thru-axle mount, featuring the robust and lightweight RR 411 rim from DT Swiss for gravel use.

Wheel building at TNC-Hamburg:

Hand-built in our specialist workshop. We manufacture these wheels entirely by hand for you, which is why we cannot offer a right of return for them. Thanks to more than 30 years of experience in wheel building, we extract the optimum in concentricity, durability and stiffness from the materials. These wheels are, of course, trued multiple times, and we also pre-load the spokes in both the radial and tangential directions. This eliminates the need for re-truing over a long period of time. We use DT Swiss spokes exclusively. These ensure outstanding durability of the wheelsets. For DH and Enduro use, we recommend brass nipples.

Included in delivery:

• Front wheel fully laced in our workshop and hand-trued with SON 28 Dynamo Boost, RR 411 rim and DT spokes.
• Excludes rim tape and valve

Schmidt Son 28 hub dynamo:

The SON 28 hub dynamo from Schmidt offers excellent smoothness and very high efficiency. Manufactured and developed in Germany, Schmidt dynamos generally last longer than the bikes in which they are fitted. The ideal complement is the Schmidt Edelux lamp, as the SonDelux lamp is particularly low-loss yet still produces plenty of light at low speeds.In the standard version, the flange spacing and bearing spacing are increased by 12 mm and 10 mm respectively compared to the SONdelux. Compared to the predecessor model, the SON 28 Classic, idle losses have been reduced by approximately 15 per cent and the weight by 140 g. The SON Schmidt Original Hub Dynamo, 28 Hub Dynamo, has been the standard for high-quality, fail-safe bicycle lighting for years and, as a result of its design, remains unmatched even by new products from much larger companies. The secret lies in its gearless construction using high-quality materials and the adherence to tight tolerances, which is likely only achievable through hand-crafting by a dedicated small team. The dynamo is simply switched off electrically. Thanks to optimisation, the no-load losses when switched off amount to just 1 watt and are imperceptible even to the most sensitive riders whilst cycling.

DT Swiss RR 411 DB Rim:

The RR 411 road and cyclocross rim from DT Swiss for use with disc brakes, very light at just 410 grams and stable thanks to a high-strength aluminium alloy and 21.5 mm rim width. The rim’s asymmetrical design allows for more even spoke tension, which significantly increases stability and service life. Cleanly finished, with a welded joint, CNC-machined sidewalls and a 21 mm deep rim bed, the DT Swiss RR 511 DB is the ideal rim for building very lightweight wheelsets.

The DT Swiss RR 411 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 411 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 middle section for robust, lightweight wheelsets. We recommend these spokes for virtually all wheelsets. Extremely durable and sufficiently lightweight, the 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 Swiss Aero Comp spokes:

Designed for stable, laterally stiff yet aerodynamic wheelsets, the DT Swiss Aero Comp spoke is first cold-forged in the middle section to make 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 combination 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:

Completely redesigned with a 2 mm spoke head and 2 mm spoke thread, and aerodynamically tapered to 1.3 mm at the centre, the Revolite is the stable all-round spoke. The DT Revolite is the ideal choice for riders looking for a spoke that combines durability with low weight. Double cold-forged spoke made from rust-proof 18/10 chrome-nickel steel with a 1.3 mm thick and 1.58 mm wide semi-aero centre section.

DT Swiss Pro Lock Squorx Pro Head spoke nipples:

The Squorx Pro Head nipples are required for the new DT Swiss rims in the new tubeless-ready series. Want to increase the lifespan of a wheel several times over? That’s only possible with DT Pro Lock! This nipple features an integrated thread-locking system, developed and manufactured by DT Swiss. The two-component adhesive in the nipple thread prevents the spoke-nipple connection from loosening under the influence of operational loads and the cycling of the wheel during riding, thereby ensuring constant spoke tension.
