Racing comfort geometries
Jena's 60TON monocoque carbon frame comes in 5 sizes (from XS to XL) with geometries that allow a high level of comfort, without sacrificing reactivity and performance, which is very close to the one of Wilier's racing bikes.
The head tube, with a more open angle, ensures riding quality and stability also on the most difficult tracks. On the other hand, the rear triangle was designed to have a more distinct response to vertical stress, absorbing thus great part of the vibrations generated by the ground imperfections.

Usability
There are no limits on Jena usability and to the available configurations. The span between frame / fork and wheels allows you to install generous tyres on 28” wheels or MTB wheels with a 650B diameter. With 28” wheels you can install tyres up to 44 mm wide, whereas in case of 650B MTB wheels, you can even install 48 mm wide tyres, which is equivalent to 1.95” (tested on Vittoria tyre).
There are numerous available supports that allow the installation of bottle holders, bags, carriers or mudguards. On the front fork, for example, you can install two bottle holders or one lowrider carrier for bags.

Flatmount disc brakes
Jena is available only with flat mount disc brake. The standard installed rotor has a 160 mm diameter. The wheel through pins have a 12mm diameter, 100mm long on the front fork and 142mm on the rear one.
Kamm tail design
An aerodynamic oblique tube was developed for Jena. This gives the classic truncated tail shape of Wilier's aerodynamic frames.
Removable derailleur support
The derailleur support can be removed in case of single ring group, which is a transmission widely used by gravel enthusiasts. In any moment, you can choose a solution with double or single crankset, without compromising on the bike look.
