The carbon frame is manufactured in a small series with a "private mold" in Asia exclusively for Koba. The bikes are individually assembled in Buchs according to customer requirements.

Jan Koba attaches great importance to weight-optimized bikes and says about the Trailtool-ND:

"What speaks in favor of the Trailtool is that it was built specifically for the terrain found in Switzerland. In other words: long climbs (shock and fork can be locked), which are also technically demanding (e.g. Davos trails), and rough descents. Trailtool = a bike for maximum fun on trails of all kinds. With our custom-made system, you can take your personal needs into account (e.g. the wheels specified for lightweight women are not as heavy as those specified for a 100-kilo man)."

Equipment

As befits an ex-racer and bike company owner, Jan's Trailtool is equipped with only the best. In addition to the high-end suspension from Fox, a 12-speed XTR groupset with 4-piston brakes from Shimano is installed. Pimped with a classy Next carbon crank from Race Face and lightweight wheels with Toboga carbon rims and DT's 240 hubs.

Processing & details

The carbon frame is finished to the highest standard and attractively painted. The design of the frame is appealing and is somewhere between solid and sporty. Large bearings are installed and details such as the cable routing or the rear rocker are neatly implemented and more attractive than on some "big" brands. The "all rideable" lettering on the seat tube and top tube is the most inspiring feature, motivating you to embark on new adventures.

The chainstay protector is generously dimensioned, but unfortunately it doesn't dampen the chain slap sufficiently.

On the flat

The race gene of Koba Bikes is noticeable, you sit slightly stretched on the Trailtool and benefit from the good propulsion. The result of a stiff frame and lightweight equipment. The bike gives good feedback from the ground and can be steered precisely.

Up the mountain

Light-footed and with optimum traction, the Koba climbs steep and exposed slopes with ease. You are well advised to keep the cockpit low so that it does not climb. The Trailtool takes a lot of momentum from obstacles and glides smoothly over them.

Downhill

On descents, the rear end quickly releases a lot of travel and the end progression only comes into play very late. The rear shock really rushes through its travel, which is a little unusual at first, especially because the rear end still feels somehow firm - probably the race gene. You quickly get used to it and shoot to the valley with precise steering behavior.

Conclusion

Long days in the saddle are the workshop of the Trailtool. The combination of race-oriented handling, a forgiving rear end and light weight make the hours in the saddle pass quickly. Koba's custom options are ideal for anyone who doesn't like "off the shelf".

Recommendation

Because the rear quickly frees up a lot of suspension travel, it is predestined for lightweight riders. With complete bikes, they can often only use part of the travel.
