The Elite Chainring was developed in cooperation with FES, the Institute for Research and Development of Sports Equipment. It was developed especially for the demanding requirements of professional track cyclists and their frames. Meanwhile, top athletes are using up to 70T chainrings on their hunt for the best times. With chainrings of this size, it is extremely important to guarantee the rigidity of the chainring when subjected to high loads. Thanks to special struts on the interior, it has been possible to achieve the necessary stiffness while simultaneously reducing weight. Only high-quality 7075/T6 aluminium is used as the raw material.

The 2-speed bottom bracket gearbox “Doppio” from Kappstein is a compact, light and comfortable transmission unit in the bottom bracket bearing. Thanks to the extremely compact design, the entire gearbox is only 1cm wide and only about 200g heavier than conventional bottom brackets. The Doppio offers the driver a ratio of 1.57 in the heavier 2nd gear. This allows the number of gears to be increased with many possible combinations.

Type: Mid-Motor

Shape: Cylindrical

Max Torque: 95Nm (standard); 75Nm (light)

Weight: 2.2Kg (Standard); 1.8Kg (light)

Size: ø90mm only

Benefits: Narrow Q Factor, Standard ISIS shaft (suitable for any ISIS crankset)

The SF-HUB has a noiseless freewheel and simultaneously excels with close to zero backlash. This instant engagement means that the energy that the rider applies to the pedals is transferred directly to the rear wheel without the annoying backlash. This is made possible due to a modified, innovative principle with regard to the conventional roller freewheel. An exceptional riding experience that will never cease to surprise every time.
