Description

GO ANYWHERE FAST

The RATT CF2 allows you to go anywhere fast. Equipped with a Shimano GRX RX400 groupset, RONDO Lit wheels with supple 47 millimeter-wide Vittoria Terreno Zero tyres, and an ergonomic Selle San Marco SHORTFIT saddle on a shock-absorbing carbon frame, it’s a modern feat of engineering. While wide tyres create unreal traction, the increased fork rake creates low trail geometry for razor-sharp steering – a match made in heaven for boundless riders. Transitions from smooth pavement to broken side roads, and gravel paths to forest tracks are a breeze, with the RONDO Flare handlebar offering additional comfort and control. The RATT CF2’s capability will ignite a spirit of adventure in even the most urban of cyclists.

Thanks to the unique TWINTIP fork you can change your position and adjust the steering character of the bike.

 

This unique solutions let's you adjust your riding position and the handling of the bike. Choose between a low position and snappy handling, or a more upright position and relaxed steering. The concept has already proven itself on the Ruut gravel bike. We are not claiming it's two bikes in one, or that we have invented the wheel. But it works, and you will be supprised just how much more stable the bike feels on rough, technical descents in one axle position, and how much more 'road race ready' and aggressive it feels in the other.
