OK, so this is the first thing we've added to the site that doesn't really fit in with our Enduro-only ethic! 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 to be responsive, made from Series 3 6061 Aluminium with beefy double butted aluminium tubing and a tapered headtube. The Alcatraz has short chain stays with the DJ standard 135x10 horizontal drop-outs. Two sizes are available.
An awesome base for your jump bike build!
