Planet X unveils Viner Maxima RS 4.0 with 795g frame

Viner is an Italian bicycle brand that was founded in 1947 by Viviano Nerozzi, but it fell on hard times and a few years ago Planet X acquired the company, and this week it has just launched the Maxima RS 4.0, heralded as its flagship carbon fibre race bike.

The design team for the new bike is based at Planet X’s headquarters in Sheffield, and they have “combined the most up to date frame technologies to produce an ultra light weight frame that retains incredible stiffness.”

As a result of all that, it’s the lightest frame that has ever worn the Viner logo, with a claimed 795g for a size medium. It’s constructed using high-modulus carbon fibre with internal cable routing and Di2 compatibility. There’s a full carbon fork (392g) with a tapered steerer tube and oversize head tube, and a press fit bottom bracket, all to provide maximum frameset stiffness.

Frames are hand finished in Italy (they’re made in the Far East like most carbon frames these days) and sent to the UK where full bikes are assembled, with two complete bikes on offer. 

The range starts at £1,999.99 with a full Shimano Ultegra 11-speed groupset and Shimano RS330 wheels. A Selcof aluminium handlebar, stem and seatpost finish off the bike, and it comes in at a claimed 7.55kg. 

Step up to £2.499.99 and you get a Shimano Ultegra Di2 groupset with RS91 C24 wheels, the same Selcof aluminium handlebars and stem but with an FSA SL-K carbon fibre seatpost, changes that bring the claimed weight down to 7.15kg.
