Tune Nano Road and Nano CS Road: the patented hub that frees up the carbon spoke

After gravel, Tune brings its Nano platform to the road. On 28 July 2026, the German brand presented six carbon wheelsets: the Tune Nano Road with steel spokes and the Nano CS Road with carbon spokes, each in 35, 45 and 60mm. They weigh from 1180g to 1440g a pair, cost from €2290 to €3420 and accept up to 130kg total weight. At the heart of the range is a patented hub designed for carbon spokes.

Tune Nano Road and Nano CS Road: six wheelsets, one rim

Tune, based in Buggingen in southern Germany, made its name with its hubs and ultralight parts. On the road, its wheel range was until now led by the Yokto, designed for minimum weight. The Nano Road target a different use: a robust, versatile wheel, from long training rides to racing. Tune had already collaborated with Reserve on the Reserve SL Tune Pico used by Visma | Lease a Bike, but these are complete Tune wheels.

The range is split into two families that share exactly the same rim. The Nano Road get 24 Sapim CX-Ray steel spokes per wheel on a 24-hole Nano hub. The Nano CS Road move to 20 Tune aero carbon spokes per wheel, on the new 20-hole Nano CS hub. Each family comes in 35, 45 and 60mm rim depths.

A hooked, UCI-approved rim with a 24mm internal width

On all six wheelsets, the carbon rim measures 24mm internal width and 32mm external width. It is hooked, tubeless ready and UCI-approved. Tune claims compatibility from 28 to 45mm, optimised for 28 to 30mm tyres, and a maximum pressure of 7 bar (102 psi). The hooks let you ride tubeless or with inner tubes, with no restriction on tyre brand. To check your set-up, our rim and tyre compatibility guide sets things out.

A design detail: the 45 and 60mm rims are symmetrical, whereas the 35mm version uses asymmetric rims front and rear. According to Tune, the gain in stiffness outweighed the small aero loss.

Nano CS: the patent that frees up the carbon spoke

This is the heart of the range. A carbon spoke must work in a straight line between hub and rim. According to Tune, this has until now required a hub body designed for a specific rim geometry, and therefore a dedicated, expensive part. Tune has patented a hole machined with a ball-end mill: the spoke head can pivot in its seat and aligns itself towards the rim hole. Tune speaks of a straight spoke line, with less stress.

The practical consequence: the same Nano CS hub works with all three rim depths. Tune states on the hub’s product page that it suits almost all rims, with a caveat for road rims around 65mm depending on their offset. Tune says it has tested the system up to 700Nm of torque. The hubset is also sold separately: €750, or €1380 with ceramic bearings according to BikeX. Tune says it is handmade in Buggingen.

To put this approach in context, DT Swiss did the opposite with its ARC 1100 Carbon Spoke: carbon spokes combined with hubs and rims designed together. Tune is betting on a universal hub.

POEtry 69 hubs and Enduro bearings

Both families use the POEtry 69 system and its 69 points of engagement. Cycling Weekly specifies that an optional internal pawl system doubles this figure to 138, against 40 on the Yokto 4550.

For bearings, Tune fits steel Enduro bearings as standard. The Enduro XD-15 ceramic option costs €630 more and comes with a lifetime warranty. That makes you think about the real benefit of ceramic.

Weight and price: a 100g difference and €500 more for carbon

The weights claimed by Tune, to within ±3%, are 1280g, 1340g and 1440g a pair for the Nano Road 35, 45 and 60. The Nano CS Road come down to 1180g, 1250g and 1350g. Switching to carbon spokes therefore saves 90 to 100g depending on the rim depth.

The price does not depend on the rim depth. The Nano Road cost €2290 a pair with steel bearings, €2920 with ceramic. The Nano CS Road go up to €2790 and €3420.

My verdict

With the Tune Nano Road, Tune is not chasing the weight record; it leaves that to the Yokto. The range ticks what you expect in 2026: a hooked 24mm internal rim, 28 to 45mm tyres, 130kg total weight and a 10-year warranty. The best compromise seems to me to be the Nano CS Road 45: 1250g a pair for €2790, with a patented hub and spare spokes supplied. The Nano Road with Sapim CX-Ray spokes remain the simplest option to maintain, for €500 less.

The reservations are mainly about the figures. The strength data for the CS system are Tune’s own, and the €630 ceramic option adds considerably to the bill for a debatable gain.
