The Valais bike manufacturer Ribisu caused quite a stir with its frames milled from a single block of aluminum. However, this unique idea did not stop there. From then on, Ribisu creator Adrian Summermatter opted for carbon and worked on a concept that comes very close to the egg-laying wool-milk sow: a frame for downhill and trail use in equal measure. At the beginning of December 2019, the frame project became concrete and Summermatter revealed the first details.

Versatility lies in the design

The RibisuRocket frame features the Boost axle standard and is designed for 27.5-inch wheels and tire widths of up to 2.8 inches. It offers a full 204 millimetres of travel and a downhill geometry that is compatible with single and double crown forks.
Despite this, the bike is kept agile with a wheelbase of 1218 millimetres and 432 millimetre chainstays. It also has a centered, low center of gravity. As a result, it rides playfully and is ideal for park and downhill-oriented trail rides - a bike between downhill and super enduro, reveals Summermatter.

The steering angle of the RibisuRocket is 63.4 degrees, while the seat angle of 75 degrees also guarantees propulsion when a counter-climb needs to be tackled.
There is currently one frame size in medium. This is suitable for riders between 175 and 190 centimetres tall.

Fine choice of materials

Summermatter uses the finest Toray DU carbon for the frame construction and the Valais-based company also attaches great importance to other details. Not only are the gear cables and brake lines routed internally, but the frame also has internal cable access for mounting a dropper post. Furthermore, the rear triangle has 14 bearings to guarantee a sensitive response. The ISCG05 mount for fitting a chain guide, on the other hand, is standard on such bikes.

At the end of last year 2019, Summermatter received the OK for its "RibisuRocket" from the testing institute. The first small series of ten frames is already in production, available for CHF 2,750, excluding shocks and shipping. Summermatter expects the first frames between mid and end of May 2020.
First and foremost, only the frame is sold, which is available in matt, glossy black or glossy black/white finishes. The RibisuRocket can be assembled with selected parts at the customer's request.
