Every Venn wheelset is built on a hub chosen for it: the spokes it takes, the holes it is machined for, the axles of your frame and fork, and your brakes. This page explains how the hubs are named, which wheelsets use each one, and what each hub takes.
How the names work
A Venn hub name reads in four parts. RESD-01 is an example:
| Part | Means | In RESD-01 |
|---|---|---|
| RE | ratchet engagement: the hub drives through ratchet rings | RE |
| S or C | the spokes it is built for: S steel, C carbon | S, steel spokes |
| D, B or R | the brake and axle family: D disc, B Boost disc, R rim brake | D, disc |
| -01, -02 | the hub within that family | -01, the first |
A new number means a different hub: the RECD-02 and RESD-02 are different hubs from the -01s, not the same hubs machined differently. A different hole count, axle, freehub or bearing on the same hub keeps its name. The Venn Helix-01 has its own name: it is a different kind of hub (below).
The hubs
| Hub | On these wheelsets | Holes, front / rear | Axles | Freehub bodies | Ratchet | Bearings | Weight, front + rear |
|---|---|---|---|---|---|---|---|
| Venn RECD-02 | 500 C UL | 20 / 20 | 12 x 100 / 12 x 142 mm thru axle | Shimano HG, SRAM XDR, Campagnolo N3W | 36 teeth | S&S ceramic | 70 g + 150 g |
| Venn RESR-01 | 360, 470, 590 and 780 S TCC (rim brake) | 20 / 24 | quick release, 5 x 100 / 5 x 130 mm | Shimano HG 11-speed | 36 teeth | steel | 61 g + 180 g |
| Venn RESD-01 | 360, 470, 590 and 5028 S; 440 S 32″ (24 / 24) | 24 / 24 | 12 x 100 / 12 x 142 mm thru axle | Shimano HG, SRAM XDR, Campagnolo N3W | 36 teeth | sealed steel | 75 g + 181 g |
| Venn RECD-01 | 360, 470, 590, 500 and 5028 C SL | 20 / 24 | 12 x 100 / 12 x 142 mm thru axle | Shimano HG, SRAM XDR, Campagnolo N3W | 36 teeth | S&S ceramic | 83 g + 182 g |
| Venn RESB-01 | 2430 S XC, 2430 S AM; 440 S 32″ and 2430 S AM 32″ (Boost) | 28 / 28 | 15 x 110 Boost or 12 x 100 front, 12 x 148 Boost rear | Shimano HG, SRAM XD, Shimano Micro Spline | 36 teeth | sealed steel | 121 g + 179 g (12 x 100), 137 g + 179 g (15 x 110) |
| Venn RESD-02 | 440 S 32″ and 2430 S AM 32″ (28 / 28) | 28 / 28 | 12 x 100 / 12 x 142 mm thru axle | Shimano HG, SRAM XDR, Campagnolo N3W | 36 teeth | steel | 308 g a pair |
| Venn Helix-01 | 520, 440 and 5028 HE1 | 24 / 24 | 12 x 100 / 12 x 142 mm thru axle | Shimano HG, SRAM XDR, Shimano Micro Spline | 72 teeth, helical | front 6902 and 6802; rear two 6902 and a 41.5 mm angular contact bearing | 105 g + 243 g |
The Venn RE hubs engage through a 36-tooth ratchet, every 10 degrees; the Helix-01 through its two 72-tooth helical rings, within 5 degrees. The RECD-01, RECD-02, RESD-01, RESD-02, RESB-01 and Helix-01 take Center Lock rotors; the RESR-01 is a rim brake hub.
The S and C hubs: why the spokes decide
Carbon spokes and steel spokes need different hubs. The C hubs (RECD) are machined for carbon aero blade spokes, at 20 holes front and 24 rear on the C SL sets and 20 and 20 on the 500 C UL, our lightest wheelset. Both run S&S ceramic bearings. The S hubs (RESD, RESB, RESR) take steel spokes, and the choice is wide: on the disc hubs the wheel builder offers Sapim CX-Ray, Pillar Wing 20, Pillar PSR 1420 and Pillar 1423, and we can build with other steel spokes too. On the RESR-01 rim brake hubs, any steel spoke works.
Boost, and 28 holes a side
The RESB-01 is our Boost hub for mountain bikes: 12 x 148 at the rear, with a 15 x 110 Boost or a 12 x 100 front, 28 holes front and rear. The RESD-02 gives the 32-inch wheelsets 28 holes each side on standard 12 x 100 and 12 x 142 thru axles, for frames without Boost: on the 440 S 32″ it is the 28-hole choice beside the 24 / 24 RESD-01, on the 2430 S AM 32″ the non-Boost choice beside the RESB-01.
The Venn Helix-01
The Helix-01 is the hub that Victor took from an early, almost single-use prototype to a hub that works very well. Working with its maker in Taiwan, Victor redesigned how the 41.5 mm angular contact bearing sits in the shell, the preload system, the shell shape and the axle, and made the freehub one piece of alloy. Its ratchet engages the way a bolt tightens: the harder you pedal, the firmer its two 72-tooth rings press together. It engages within 5 degrees, and under power there is no free play to take up. Beside its two 6902 bearings, the rear hub’s angular contact bearing is built for the side loads a wheel takes when you sprint and corner. The rear hub comes with a Shimano HG freehub body as standard. You can choose a SRAM XDR or Shimano Micro Spline body instead. There is no Campagnolo freehub for the Helix-01.
DT Swiss, in the wheel builder
In the wheel builder you can also build on DT Swiss 350, 240 or 180 hubs: 24 holes front and rear, straight-pull spokes, a 36-tooth ratchet and Center Lock rotors.
Warranty
Venn hubs carry a 2-year limited warranty. Bearings are a wear part and are not covered. DT Swiss hubs carry DT Swiss’s own warranty. See the warranty terms.
