When is this frame availible? escription - Updated for 2007, the ZOO! Pitbull frame made famous be Neil Tunnicliffe now has two great geometry options! - New concept for trials... 116mm spaced dropouts means a single speed rear hub can be used with snail cams taking care of the chain tension; really simple and minimalist! This requires an 18:15 gear ratio to be used, other gear ratios can be fitted with the use of a half link. - Externally butted head tube has gussets at the top and down tubes, to help strengthen the head tube area of the frame. - CNC Machined one-piece BB shell and chainstay yoke for increased pedalling response. - Built in brake booster creates a stiff and powerful rear brake. - Chunky down tube increases weld area at the head and down tubes, increasing stifness and strength. - Brushed aluminium and lacquered finish resists scratches and looks classy! - Weight: 2.133kg/4.704lbs Geometry (with Echo Urban fork) Wheelbase: Short 1065mm, Long 1100mm Chainstay Length: 377mm BB Rise: Short 10mm, Long 25mm Head Angle: 72 degrees Centre of BB shell to top centre of head tube: Short 665mm (26.25"), Long 680mm (26.75") Off Tartybikes website
