OK, so this is the first thing we've added to the site that doesn't really fit in with our Enduro-only ethic, but pump tracks and skateparks are bang on for keeping your fitness and skills up during the shorter days! If you're lucky enough to live near a pump track, you've probably already realised how much fun they are, without committing to getting soaked and covered in mud.

This frame is made from responsive Series 3 6061 Aluminium frame with beefy double butted aluminium tubing and a tapered headtube. The Alcatraz has short chain stays with the DJ standard 135x10 horizontal drop-outs.

An awesome base for your jump bike build!
