RONDO RATT CF1- an ultimate all-road bike

Description

VARIO GEO CONCEPT

AN ULTIMATE ALL-ROAD BIKE

The RATT CF1 is the road bike of the future. Offering a newfound freedom to any cyclists, it transfers from smooth tarmac to gravel tracks with ease thanks to RONDO X HUNT 650B wheels and 47 millimeter-wide Vittoria Terreno Zero tyres. Built around a comfortable and responsive carbon frame is a robust and reliable Shimano GRX RX800 groupset, ergonomic Selle San Marco SHORTFIT saddle, and an increased fork rake for low trail geometry. The bike also features an Easton EC70 SL handlebar with a comfortable shallow drop, allowing you to shift hand positions as easily as the bike shifts across terrains. Whether you’re a curious novice or veteran cyclist looking for something more versatile, its effortless speed, comfort, and agility make it a no-brainer.

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.
