Front wheel DT Swiss 350 Disc hub plus Stans Notubes Arch rim

The lightweight and extra-sturdy 26-inch front wheel for all-mountain, trail and enduro use, featuring the new robust DT Swiss Straightpull 350 hub and the asymmetrical 431-gram Stans Notubes ZTR Arch MK4 rim. Recommended for tyres between 2.2 and 2.6 inches wide, with a 26 mm rim width.

The DT Swiss 350 Straightpull hubs are available as thru-axle models, including a Boost version, and as quick-release versions. Available with either a 6-bolt disc or Centerlock brake disc mount.

Stans NoTubes ZTR Arch MK4

Developed with the help of the Stans Enduro World Series team, the new Arch MK4 is ready to tackle any trail. Despite the increased rim width to 28 mm and featuring the proven lower BST rim bed, the new Arch MK4 retains its low weight for excellent acceleration and climbing performance on ascents. With the WideRight System introduced by Stans NoTubes, the rim width increases to 28 millimetres – for even better tyre support and full volume development. Inspired by Stans carbon rims, the new rim profile, combined with the new 6069 aluminium alloy, increases lateral stiffness and impact resistance whilst reducing the likelihood of snake bites.

Wheel building at TNC-Hamburg:

We manufacture these wheels entirely by hand for you. Thanks to more than 30 years’ experience in wheel building, we extract the optimum in roundness, durability and stiffness from the material. These wheels are, of course, pressure-tested multiple times; we also pre-load the spokes in both the transverse and longitudinal directions. This eliminates the need for re-truing over a long period of time.

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

DT Swiss 350 Straightpull hubs

With the new 350 hubs, DT Swiss offers affordable, high-quality hubs. Now featuring a significant weight reduction and 36-tooth ratchet discs. From road bike to downhill versions, the 350 hub range is designed for maximum durability. Straightpull refers to straight, non-offset spokes. Thanks to this technology, it is possible to achieve an ideal balance between weight and stability. The Straightpull spokes allow for very precise alignment and optimised positioning within the wheel, resulting in a stiffer and more responsive wheel.

DT Swiss Straightpull:

• Straightpull spoke positioning: Straightpull lacing allows for precise placement and alignment of the spokes. This optimises wheel stiffness and eliminates any unwanted stress peaks.
• Straightpull hub shell: DT Swiss straight pull hub shells require minimal material, allowing them to be constructed to be lightweight yet stable.
• Straightpull lacing pattern: With crossed lacing, the spoke anchors are designed so that the forces introduced almost cancel each other out. This increases the precision of the bearing race and further extends the service life of the ball bearings.

Notubes BST

Notubes’ Bead Socket Technology. This special rim design features a wide rim bed with a low flange for high tyre stability and full tyre volume development. The BST technology improves air retention in tubeless systems, results in less rotating mass and virtually increases the effective rim width compared to competitors. A wide rim also reduces tyre flexing in corners and allows the bike to be ridden with lower tyre pressure. The ZTR rims are fully tubeless-compatible when used with rim tape and a valve.

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 wheelsets. We recommend these spokes for virtually all wheelsets. Extremely durable and sufficiently lightweight, DT Competition spokes enable wheel building at the highest level. Thanks to the tapered section, the spokes absorb movement 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 70 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 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 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 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.
