After two years of refining and prototyping, we have finally hit the Jack Pot .

Designed for aggressive UK trails and a rider that wants a playful bike that will not only seek out the gnarliest lines, rail berms and be fun on descents but be able climb back to the top quickly and efficiently.

Onza carefully selected their own blend of "Flawless" 4130 cromoly with their premium frame builder to meet their testers exacting standards. The Snake skin welds and light weight double butted tubing were essential elements in creating this high calibre frame. The electrodeposition treatment they have used on this frame protects the frame from rusting from the inside out. A simple must when you have internal routeing for a stealth dropper seat post.

The frame is supplied with rubber grommets to keep your cabling neat and tidy and blanks if you decide to take them out. The pronounced tapered head tube keeps steering inputs stiff and responsive and the PF30 bottom bracket will allow future upgrades to our eccentric PFBB that is currently in development allowing you to convert to a single speed rig. The unique one piece yoke adds stiffness to the BB area while still allowing for the playful resilient feel that steel is renowned for.

To complete the frame details we selected stiff CNC machined bolt thru 12mm rear drop outs and comfortable snaked forged stays. Combine all this with Progressive modern geometry and a carefully selected part list and you have the ultimate UK hardtail.
