  • Vitus Zenium CR Road Bike (105)

    The Zenium CR is a carbon road bike that's ideal for local criteriums, fast sportives, weekend club runs and is also a comfortable and super-reliable training bike. It features a full carbon frameset that's equipped with a Shimano 105 2x11-Speed groupset with hydraulic disc brakes. This bike provides high-performance for efficient hill climbs, fast sprints and offers all-day riding comfort for long days in the saddle.

    Full Carbon Frameset Optimised for Performance and Comfort

    The Zenium is designed to offer the perfect blend of comfort and performance for a great all-round riding experience. The compact geometry and slender dropped seat stays increase comfort and give a balanced ride. The UD carbon fork features a tapered steerer for steering precision and inspiring handling, balancing confidence and control. We’ve built in up to 32mm tyre clearance to give you more choice. The frame is a fine balance of classic tube shapes and modern features, put together in a package that keeps weight to a minimum. Make no mistake, the Zenium wants to go fast! However, the subtle nods to all-day comfort ensure that if you are looking for a carbon road all-rounder, then the Zenium is for you.

    Shimano R7000 105 11-Speed Groupset

    The Zenium CR Disc bike features the Shimano 105 R7000 11 speed groupset. The new development of 105 from Shimano adds some superb ‘trickle-down’ technology with a major highlight being the new smaller shape shifters, powering the 105 R7020 hydraulic flat mount disc brakes. Coming in a gloss black finish, this new 105 groupset looks fantastic.

    Vitus Custom Wheels and Vee Road Runner Tyres

    Rolling on our Vitus clinchers, and lightweight hubs, paired with the super cool Vee Road Runner tan sidewall 28mm tyres. The new Vitus Switch axles give you the option to leave the lever handle firmly secured in either wheel or remove it for extra weight saving and aero gains. The cockpit is built with Vitus’ own 6061 Aluminium aero bar and stem, combined with a Vitus 27.2mm US Carbon layback seatpost and our own tried and tested Vitus road saddle.

    Easy Assembly

    When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools and plastic pedals are conveniently included in the box.

    Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:

    • All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
    • All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes.
    • All bikes for worldwide delivery outside the EU will be delivered in small boxes.

    This video demonstrates assembly from a SMALL BOX.

    This video demonstrates assembly from a LARGE BOX.
