SL 37: agile, stiff and affordable

U-Shape

For the best performance at high speeds – The aerodynamic U-shape has been successively optimised to achieve the best aerodynamic properties. In order not to deform the shape under spoke tension, more material with different fibre orientations has to be accumulated – nevertheless, a sensationall low weight could be achieved while maintaining stability. Aerodynamics were even more important to us for this product than minimising weight.

Inner width

22,3 mm – The best aerodynamic properties are achieved with a tire width of 28 mm.

Hubs of our trust

DT Swiss – we have been relying on the quality and longevity of the DT Swiss 240 hub for our SL series for several years now. Coupled with the low weight, the DT Swiss 240 hub is the perfect match for all important parameters for Schmolke standards. The extremely reliable freewheel system ensures direct power transmission even under the highest loads. Smooth-running bearings provide a clear advantage with their extremely low rolling resistance.

SAPIM spokes

We use steel spokes from the Belgian manufacturer SAPIM on all of our wheels. With the CX-Ray knife spoke we installed, Sapim has succeeded in developing an exceptional spoke. In addition to its low weight, it has exceptional load capacity and flexibility. This also results in the large area of ​​application. Regardless of whether it is a racing bike, gravel or MTB wheelset, they all benefit from these positive properties. In addition, the flattened middle section ensures excellent aerodynamics. The high quality of the materials enables the construction of stable wheels and guarantees a long service life.

Agile and affordable

With their agile character, the wheels are born for the mountains and for the undulating marathon terrain. Thanks to their high lateral stiffness, every watt reaches the road directly. The SL 37 wheels can be steered very precisely and give a calm feeling on fast downhill rides. At high speeds, the low susceptibility to wind also conveys a high feeling of safety. And all at an unbeatable price!
