Description

The Venn 440 Helix pairs our 44mm 1k filament wound 440 TCD UL rims with the Venn Helix-01 hub, whose helical drive pulls the ratchet rings together under power: 72 teeth, no free play when you push. Laced with Sapim CX-Ray bladed spokes, 24 front and rear, the set weighs 1320g. The 32mm internal width suits 40 to 50mm gravel tyres, and the rims carry no clear coat: gloss, matte or 25k filament wound.

01

HELICAL ENGAGEMENT

In an ordinary ratchet hub, springs push the drive rings together and a little play stays between the teeth. In the Venn Helix-01 the drive torque itself pulls the two 72-tooth ratchet rings together along a helical spline: the harder you pedal, the more firmly they mesh. It engages within 5 degrees, and under power there is no free play to take up, out of the saddle, in a sprint or on a steep climb.

02

ROLLING UNDER LOAD

Beside its two 6902 bearings, the rear hub runs a 41.5mm nano-coated angular contact bearing. It takes side loads as well as radial ones, so it keeps its alignment under the weight of a rider and the force of a sprint, and the wheel keeps rolling freely when it matters. Cold-forged shell, 15mm 7075-T6 aluminium axle, forged and CNC-machined SCM 415 steel ratchets. Made in Taiwan.

03

1K FILAMENT WOUND RIMS

Each carbon tape carries exactly 1,000 fibres, so every fibre goes where it is needed. The 440 TCD UL rim weighs 350g, is 44mm deep and 32mm wide inside (39mm outside), and carries no clear coat: choose gloss, matte or the 25k filament-wound surface, all at the same price.

Questions riders ask

What does helical engagement do?

In an ordinary ratchet hub, springs alone hold the rings in engagement and a little play remains between the teeth. In the Helix-01 the drive torque pulls the two ratchet rings together along a helical spline, so the more torque you put through it, the more firmly it engages. Under power there is no free play.

How heavy are the hubs?

The Helix-01 front hub weighs 105g and the rear 243g, and both are included in the 1320g wheelset weight. Hub weight sits close to the axle, so it barely changes how the wheel accelerates.

Which freehubs and axles fit?

Shimano HG (for Shimano 11 and 12-speed road cassettes) or SRAM XDR. Axles are 12 x 100mm front and 12 x 142mm rear thru axle, with Center Lock rotors. There is no Campagnolo freehub for the Helix-01.

Which tyres work best?

The 32mm internal width is made for 40 to 50mm gravel tyres, tubeless or with inner tubes. Tubeless tape is included.

When will my wheels ship?

Each set is built to order around its Helix-01 hubs and ships in about 35 days, free worldwide.
