Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Marin Alcatraz 2 in Red/Purple

Season:2026

Brand:Marin

Code:7418780REDPUR

Unleash almost endless possibilities in the Matt Jones matrix with the Alcatraz 2. A jump-busting Manitou Circus Expert fork smooths landings, while PNW’s Range handlebars and Marin CNC stem are the premium touch you deserve.

The Series 3 aluminium frame is big-line tough and spin-it light. Dialed with short chainstays for poppy manuals and a low frame so it won't cramp your style – its geometry lets you level up without limits.

With the Alcatraz 2’s sorted spec, nothing holds you back. Boost higher, dump the front end deeper or push for that flip – the Alcatraz gives you the freedom. Big move confidence is backed up by the Manitou Circus Expert’s 100mm of travel. PNW’s 38mm rise Range handlebars take the sting out of harsh landings while looking the part. Keep your speed in check with Tektro’s four-piston hydraulic rear disc brake.

The build keeps maintenance to a minimum without stripping features and lets you push your limits. Built from 6061 aluminium, the Alcatraz’s Series 3 frame has carefully crafted tubes designed to handle the rough and tumble of airborne antics. Lightweight and tough, the frame has got what matters and none of the clutter that doesn’t. Internal cable routing keeps it looking sleek and cuts the rattle.
