Tune TSR 27


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.

Sapim CX-Ray

A double butted spoke is drawn to its specific profile, which defines its high strength. The short 2 mm section of the D-Light reduces weight especially on the threaded side. The 2mm section starts just at the beginning of the thread. Therefore, the rotating masses at the end of the spoke are especially reduced. This brings benefits to both the acceleration and braking qualities of the wheel. The use of 14G nipples offers a wide variety of combinations. The middle section is increased to 1,65 mm, which makes the spoke much stiffer and brings less torsion during truing than a 1,5 mm middle section. This results in an easier building process of the wheels.

The tuning of running wheels has the most noticeable effect when it comes to weight savings. All the wheels are hand-fed, pressed and perfectly centered. Our bikes stand for the highest quality and have proven themselves over millions of kilometers.
