Viner Maxima RS 4.0

Viner Maxima RS 4.0 Lightweight Road Race Bike

The Viner Maxima RS 4.0 is every bit the thoroughbred. Designed and hand finished in Italy it's the lightest frame ever to bear the Maxima name and it's a razor sharp, ultra efficient fast road bike designed for the most demanding riders.

Hand built from High Modulus carbon fibre the Maxima RS 4.0 exhibits all the traits you'd expect from a top-of-the-line fast road bike; steering is precise with confidence-inspiring handling that lets you throw the Maxima into every bend, frame stiffness threads the thin line between ultra efficiency and comfortable, and when the road points upward the RS 4.0 surges away from the pack. If you want to make your mark at the head of the bunch ride the range-topping Maxima RS 4.0
