Skyliner Tubular

“Could it be any extremer?” asks ‘Roadbike’ in its July issue.

"The TUNE wheelset Skyline receives "Best buy" in the category of lightweight climbing wheels in the Roadbike magazine!"

The Tune Skyline Wheelset won the ‘best buy’ award in the lightweight climbing wheels category as tested by Roadbike magazine. There’s really not much more to say… With 930 grams, TUNE sent the lightest wheelset to the test.
“Those that have the opportunity to take this outrageously expensive lightweight wheelset for a spin, will quickly realize that the creators are working at the limits of what is possible. Because with this wheelset any bike runs extremely light footed – if you’re talking about propulsion, you’ll almost automatically use expressions like ” rocket-like” … ”
Our two super hubs MAG150 and MIG45 form the center of lightness of the Skyliner wheelset. They’re laced with Sapim CX-Super spokes that are made for Tune.

Additionally, every crossed spoke gets hand taped, and completed with the AX-Lightness 28C rim.

Minimal weight, gorgeous good looks and hand-built quality will seduce you.

SAPIM CX-Super Spoke

The SAPIM CX-Super Spoke are lightest steel spoke ever made. The SAPIM CX-Super Spoke has been developed for extra light wheels. A new grade of stainless steel enables SAPIM to reduce the diameter of the spoke, whilst increasing its strength and fatigue resistance. Effectively, the SAPIM CX-Super is 17% lighter than the SAPIM CX-Ray and its strength is increased by 120N in the middle section versus that of the SAPIM CX-Ray.


We use standard bearings. This means you can also buy bearings in Australia if you need to. Ours are just a little special, with two main differences:

  • Our bearings have a higher fat filling grade. 30% is standard, whilst ours are filled to 50%. This not only prolongs their life, but also provides a better seal.
  • Standard bearings have variations in play from their production.
Tune bearings have the play specially determined dependent on their use. One single Tune bearing is not standard – the bearing in the free-wheel body on the left. It is constructed specifically to withstand high forces and last extra long.

Carbon wrapping

The spoke crossings are wrapped with Carbon fibre, which gets strengthened with resin. This increases the wheel quality. The result is that the spoke construction becomes more stable, several components are connected to one stiff, long lasting unit. The increased stiffness leads to a more direct reaction when riding out of the saddle and enables precise steering. In the case of an overload, e.g. by a shock, the most stressed spoke gets released by the spoke it is wrapped with.
