The Trailtool 29 is already the second private mold project of the fine Rhine Valley bike brand. This means that this frame is only available from Koba and is not an inexpensive open-mold solution to which other brands also have access. As with the first private mold project, the enduro plane "Reamol C1", Ralph Lippuner and Jan Koba are once again the developers behind it.

Geometry for riding fun and efficiency

Jan Koba, who has a background in racing, has thoroughly thought through the frame geometry and optimized it down to the last detail. This ensures that the Trailtool 29, regardless of the version, is very efficient uphill, but also offers unbridled downhill fun. The seat angle of both versions is a steep 75.5 degrees, while the head angle is 66.5 degrees, or 65.5 degrees for the Enduro version. The top tube length and reach for size M are 609 and 450 millimetres respectively.

The frame is consistently designed for 1x12 drivetrains, allowing the rear triangle to be supported as wide as possible. Together with the short chainstays, this results in high lateral stiffness.

One frame, two bikes, your choice of components

Koba offers the Twentyniner in two versions: With 135 and 140 millimeters of suspension travel at the rear and front as a sporty all-mountain version and as an ND version for enduro use. This version comes with 150 millimetres of travel at the rear and 160 millimetres of travel at the front.

As is usual for the brand, the weights are relatively low. The Trailtool 29 AM weighs just 11.2 kilograms, while the lightest Enduro version weighs 12.2 kilograms. However, customers can configure their bike according to their own wishes.
