  • Marin Rock Spring 1 27.5 Hardtail Bike

    Ready to hit the XC trails, the Rock Spring 1 is built around Marin's 6061 aluminium frame and comes with a solid and reliable components package. The components include Shimano's dependable Acera/Altus 2x9 speed gearing and a compact 36/26T Suntour chainset, so you can attack technical climbs and get quickly up to speed on the flat.

    Tektro Hydraulic Brakes and Schwalbe MTB Tyres

    When it's time to descend, you can reply on the powerful Tektro hydraulic brakes to scrub your speed in an instant. Also, this capable hardtail rolls on Marin’s own super-tough double walled rims and high grip Schwalbe Tough Tom tyres. An ideal choice for those new to cross country MTB and seasoned trail experts, this model offers reliable performance and excellent value for money.

    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.
