Mosaic RT-1 Disc

Disc brakes are not about stopping faster, they are about having confidence in your stopping power, the ease at which your hand can control braking force and reliable performance in any conditions. We've been big fans of disc brakes and were early adopters of the technology. The RT-1 disc-equipped model is a prime example of how disc brakes can be applied to a metal frame. Increased tire clearance, clean aesthetics of internally routed brake lines, and shifting lines accompany the pure function of disc brakes.
​
All this added to the particular blend of oversized internally double butted and thin walled straight gauge tubes make a responsive handling characteristic without losing the quality ride titanium frames are known for while keeping the weight as low as possible. Complemented by full custom geometry and choice of raw etched titanium the RT-1 will truly be unique to each rider.
