  • Niner RLT 9 RDO 2-Star Tiagra CX Bike

    Versatility, power and poise come to the fore with the RLT 9 RDO 2-Star Apex CX, an adventure-seeking all-action ride that takes any terrain in its stride. Featuring a superb Shimano Tiagra drivetrain, full carbon forks and Niner's own fast and furious-rolling Alloy wheels, big fun is on the cards with this drop bar dominator.

    Hard-Riding and Fast-Running CX Bike

    Centred around an RDO Carbon Compaction constructed frame, this capable CX'er is stiff and responsive while keeping a low weight, careering through courses and over obstacles with power and precision. Driven on by an efficient and hard-working Shimano Tiagra 2x10 drivetrain, shifting is swift and seamless as you build up speed and find the right gear for the ground you're running. Eating up every impact as you bound over bumps and rumbles are a full carbon Niner fork and Niner Alloy wheels, cushioned with Schwalbe G-One tyres for ultimate smoothing of the roughest routes to victory. Keeping an eye on your speed, descents and corners is a fast-acting hydraulic brake system, offering instant engagement as you react to everything the ground throws at you.

    Hard and fast riding has never been as thrilling as with this colossus of a Cyclocross steed.

    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 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.
