The Sabbath is the first of the new generation of gearbox bikes. It’s taken the Diamondback product design team, testers and engineering partners nineteen long months. The first “Black Sabbath” mule was built in August 2006 after 5months of CAD analysis and tested over the winter months in torrid British weather conditions.

Universal Transmissions have refined, lightened and evolved the early G-Boxx1 gearbox. It’s now a lightweight, fully enclosed 7speed transmission system. The Diamondback Sabbath is available as complete race bike or frame kit consisting of frame, G-Boxx inc shifters and rear sprockets, custom zero dish rear hub, Fox DHX4.0 rear shock, FSA Orbit DH headset and seat clamp.

Twist grip shifters are supplied, but rapidfire style shifters will be available soon and is a free upgrade for those who buy this beauty!
