The Alcatraz was designed from the ground up to be the best dirt jump and slopestyle bike you have ever ridden. We worked hand- in-hand with Matt Jones to define the exact needs of a modern dirt jump frame, and are proud to release the complete Alcatraz into the world. The 6061 Series 3 aluminum alloy frame is stiff and overbuilt for abuse, with a tapered headtube and 135x10mm horizontal drop outs. Available solely as a complete bike, so there is less time between you and throwing big whips and flips.

SLOPESTYLE

PUMP TRACK

SKATE PARK

The Alcatraz allows the rider to follow in Matt Jones’ footsteps to build and personalize the best dirt jump bike possible. At home boosting your local 6 pack, ripping up the pump track, or hitting the local skate park the Alcatraz has what you need to take care of business.

The Alcatraz features a 6061 Series 3 alloy frame, with a burly double butted tubesets for the best ride quality and stiffness, tapered headtubes for maximum strength on big jumps, and horizontal drop out with slotted IS disc brake tabs.

Marin have optimized the chainstay length of the Alcatraz to make sure you can have the shortest chainstays possible, giving you the ability to pop a wheelie or manual anywhere at anytime.

    View All FAQ's
    How does the DASH Store work?

    At DASH, we've created a Cycle to Work enabled storefront which allows you to browse and order a range of items, all whilst benefitting from savings of 28-47%. The cost of items you order is split into 12 months and deducted from your gross (or pre-tax) salary, allowing you to save on income tax and national insurance contributions, which is called salary sacrifice. After 12 months, you'll be able to continue using your items at no extra cost.

    What items are available on DASH Store?

    We have a range of items, from bikes and e-bikes, to accessories (such as helmets and locks), bike parts and tools, clothing (including jackets, shorts, shoes, and everything in between), even pre-owned bikes. We work with a range of brands so there's sure to be something you like in stock.

    Can I use other Cycle to Work scheme vouchers on DASH Store?

    Since we are a Cycle to Work scheme ourselves, we cannot accept vouchers from other scheme providers. If you would like to use DASH and already have a voucher, it might be worth speaking to your employer to see if they are able to refund it.
