IN BRIEF
Tune rounds out its Nano family with six carbon road wheelsets, offered in 35, 45 and 60 mm rim depths. Three of them, the Nano CS Road, use carbon spokes and a hub whose spoke-to-hub interface has just been patented. The German manufacturer claims 1,180 g a pair for the lightest, against 1,280 g for its steel-spoked equivalent, with a 3% tolerance. The brand says all six share the same hooked rim, 24 mm internal, UCI-approved and compatible with tyres from 28 to 45 mm. On the brand’s website, the Nano Road starts at €2,290 and the Nano CS Road at €2,790.

The carbon spoke has been around on road wheels for several seasons. What changes here is the way it meets the hub. Tune adds six pairs to its Nano range — three with steel spokes, three with carbon spokes — and puts forward a part the German manufacturer has had patented: the hub shell that takes those spokes.
A hub that lets the spoke find its own angle
A steel spoke tolerates being twisted a little during the build. A carbon spoke, far less so: it needs a clean path between hub and rim, with no forced angle. Yet, Tune points out, rim depth, offset and effective diameter all alter that angle — which in principle calls for a different hub geometry each time.
Tune’s answer lies in a piece of machining. According to the manufacturer’s description, the spoke holes in the Nano CS shell are counter-milled so that the spoke head sits naturally in line with the rim hole, instead of being locked at a fixed angle. According to the brand, the same hub therefore serves all three rim depths while keeping a clean spoke line.
One hundred grams separate the two families
The gap between the two versions is constant: around 100 grams a pair, in favour of the carbon spokes. Tune claims 1 280, 1 340 and 1 440 grams for the Nano Road in 35, 45 and 60 mm, against 1 180, 1 250 and 1 350 grams for the corresponding Nano CS Road, 3% tolerance included.
In 60 mm, the Nano CS Road is quoted at 1,350 grams — with a UCI-approved hooked rim and a permissible system weight of 130 kg, according to the manufacturer’s spec sheet. It is that last figure that sets these wheels apart most from a pure race pair: Tune claims broad use rather than a set kept for race days.
Rims cut out for wide tyres
All six pairs share the same hooked carbon rim, 24 mm internal width and 32 mm external. Claimed compatibility runs from 28 to 45 mm of tyre, with the brand quoting an optimisation for 28 to 30 mm. Enough to cover fast tarmac as well as broken surfaces, without changing wheels.
On the drivetrain side, the hubs take the brand’s POEtry 69 freehub system, with a choice of several cassette body standards — XD/XDR, MicroSpline, Shimano HG and N3W. The Nano CS Road are built with 20 aero carbon spokes at the front and at the rear alike.
The entry price, and what it covers
On the brand’s own store, the steel-spoked Nano Road starts at €2,290 and the carbon-spoked Nano CS Road at €2,790, across the three depths. The price climbs to €2,920 and €3,420 for the version with ceramic bearings guaranteed for life. All six references are listed as available to order, and Tune covers its wheels with a ten-year warranty.
Tune’s bet lies in that patented part: rolling out the same architecture across three rim depths while keeping a single hub, where a carbon spoke normally imposes a dedicated geometry for each model.
