BIKE JENA GRX 1X11 MICHE CONTACT

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 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, thus absorbing a great part of the vibrations generated by the ground imperfections.
There are no limits on Jena's usability and the available configurations. The span between frame/fork and wheels allows you to install generous tires on 28” wheels or MTB wheels with a 650B diameter. With 28” wheels, you can install tires up to 44 mm wide, whereas in the case of 650B MTB wheels, you can even install 48 mm wide tires, which is equivalent to 1.95” (tested on Vittoria tire).
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.
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.
Even if the aerodynamics on gravel has less importance, an aerodynamic oblique tube was developed for Jena. This gives the classic truncated tail shape of Wilier's aerodynamic frames.
The derailleur support can be removed in the case of a single-ring group, which is a transmission widely used by gravel enthusiasts. At any moment, you can choose a solution with a double or single crankset, without compromising on the bike look.
