Gravel wheelset: DT Swiss 350 Disc hub plus DT Swiss XR 391 rim

Sturdy and lightweight wheels for gravel use, featuring robust DT Swiss 350 Classic J Bend hubs and DT Swiss XR 391 rims with a 25 mm rim width. The XR 391 rims, with a 25 mm rim width and weighing just 440 grams, were originally developed for MTB use but are also excellently suited for gravel riding.

The DT Swiss 350 Classic hubs are available in both thru-axle and quick-release versions. Choose between 6-bolt or Centerlock disc brake mounts and 28- or 32-hole rims. We offer the rear wheels with freehub bodies compatible with Campagnolo ED + N3W, Shimano HG11 + HG10 + Micro Spline, and SRAM XDR + XD cassettes.

Weight from 890 grams, depending on the version chosen

Wheel building at TNC-Hamburg:

We hand-build these wheels exclusively for you. Thanks to over 30 years’ experience in wheel building, we extract the optimum in concentricity, 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 enduro use, we recommend brass nipples.

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

DT Swiss XR 391 DB rim:

The lightweight aluminium rim from DT Swiss, the XR 391 MTB to gravel rim for racing use. Thanks to extensive FEM analyses, the DT Swiss XR 391 rim features material only where it is actually needed. These rims are supplied with special DT Squorx Pro Head nipples and must only be laced using these nipples. With the XR 391 rim, DT Swiss offers a rim for cross-country racers that also performs well on the trail. Cleanly finished, with a welded bead and a glass bead-blasted, anodised finish, the DT Swiss XR 391 offers extremely low weight combined with good strength. Recommended for a maximum combined weight of rider and bike of 110 kg.

The DT Swiss GR 531 DB rims are high-end rims with a special spoke nipple mount and are supplied with special DT Squorx Pro Head nipples in silver and PHR washers; they must only be laced using PHR washers.

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, technically high-quality hubs. From road bike to downhill versions, the 350 hub range is designed for maximum durability. Equipped with high-quality seals and bearings, they are the 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 Star freehub 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 Competition spokes:

The double cold-forged spoke made from rust-resistant 18/10 chrome-nickel steel with a tapered middle section for robust, lightweight wheels. We recommend these spokes for virtually all wheels. Extremely durable and sufficiently lightweight, DT Competition spokes enable wheel building of the highest standard. Thanks to the tapered middle 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 in the Straight Pull version is first 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 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 just an incredible 278 g at a length of 264 mm. Weight per spoke at a length of 264 mm: 4.31 grams

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.
