Alpine Trail XR Bike

VAT included.

Marin's latest long travel 29er is surely one of the best value enduro bikes on the market!

The Alpine Trail XR has a top-end Lyrik Ultimate fork and a Super Deluxe Coil Ultimate RCT shock, suspension that would normally be something you'd have to pay to upgrade to, even on bikes costing twice as much. These are the top end versions of ROCKSHOX finest too, with the 2.1 Charger Damper and all the adjustment.

Marin's buyers have done an incredible job of speccing the Alpine Trail XR, you really get the impression whoever picked the components on this bike knew what they were doing. The spec list is a carefully considered mix of trick bits where it matters and cheaper or own label parts where they can make a saving. For example, we're pretty sure you'd be happy with an SLX cassette and shifter, but crisper shifting from an XT mech is worth a few extra quid. How many bikes have an EXO+ front and Double Down rear tyre out-the-box?
