The Viner Mitus Disc is a high-class race bike designed to get you to the line quicker and in more style than anyone else. Created to take advantage of the extra stopping power and more assured handling that disc brakes offer, Viner's UCI Pro-Tour proven Mitus 0.6 frameset has been redesigned with the needs of modern competitive cyclists in mind and comes with Shimano's brand new Ultegra 8000 groupset it's faster than ever before.

  • Toray T800 + HM carbon frameset
  • Frame weight: sub 1070g, fork weight: 470g
  • Shimano Ultegra 8000 groupset
  • Wheels:Fulcrum Racing 600 Disc
Full Description


The Viner Mitus Disc frameset marries a precisely tracking, full carbon fork with our newest lightweight frame, both meticulously crafted from Toray's finest T800 carbon fibre. Our Tri-Tube rear triangle seamlessly blends oversized chainstays with thin and flat seat stays and a narrow 27.2mm seat tube to provide comfort enhancing vertical compliance. Internally routed cabling reduces aerodynamic drag and provides an uninterrupted visual flow. The Mitus Disc frame is the perfect mix of comfort and efficiency, making the most of every one of your pedal strokes.

Created with our 'EPS Inside' moulding technology, each main tube frame junction in the Mitus is laid up over pre-shaped EPS formers. This allows for a more accurate placement of carbon in the mould, eliminating material wrinkles, creating lighter frames with enhanced structural integrity and allowing absolute consistency from frame to frame.

Disk brakes are set to turn the road bike market on its head. They offer greater stopping power, modulation, mechanical leverage and they eliminate wear to your precious wheel rims. If you've ever experienced brake-fade due to heat build-up while descending a steep alpine pass you'll know exactly how big a game changer disk brakes really are.

Groupset: Shimano's Ultegra groupset has been upgraded and the result is the incredible Ultegra 8000 groupset. Shimano has worked to improved the efficiency of the shifting, improved brake feel and delivers a smoother working, better-looking groupset that's simply worth every penny.

A compact FSA Gossamer Pro chainset helps keep the weight and the cost down. The 50/34t chainset combines with an 11-28t 11-speed cassette to give an excellent gear spread, close enough for fast road work but still including a bailout gear for tackling those ultra steep climbs.

Ultegra 8000 moves to polymer coated gear cables for the slickest possible shifts. revised lever ergonomics have delivered a sweeter gear shift feel and the slightly larger downshift paddle is easier to hit with gloved hands. Inline cable adjusters are a thing of the past with the new levers containing Allen key adjustable cable pre-tensioning.

The biggest change is out back where Shimano has integrated their Shadow Derailleur design from their Dura Ace and off-road groupsets. Shadow geometry places the rear mech further under the cassette, giving slicker shifts, protecting from crash damage and allowing for larger cassettes for enhanced gear ratios. The front mech gets a new cage and pivot design to help it accommodate the wider gear ratios and trend towards wider tyre sizes.

If you've ridden Ultegra before you know how much care and attention Shimano put into it. It's their best selling groupset and offers the best mix of price/performance. This new version is no exception it's simply superb.

Wheelset: Fulcrum Racing 600 disc Fulcrum are the brand that builds Campagnolo's wheels and there's no higher reccommendation than that. Sturdy 700c rims are paired with adjustable cartridge bearings are laced to asymmetric rims for extra strength while keeping minimum weight. The Fulcrum racing Sport disc wheels are disc brake equipped for maximum stopping power and will do you proud mile after mile, season after season, they're the perfect wheel for Gravel and CX bikes.

We capped this build off with high-quality Selcof finishing kit and San Marco saddle. With a frame of this quality and groupset and finishing kit that majors on advanced design and lightweight performance you're getting a superb bike for your money, one that will keep you at the front of the bunch and keep you smiling for years to come.

You're serious about cycling, now it's time to give yourself an unfair advantage and ride the Viner Mitus Disc to victory.
