All frames come complete with chaintug / axle positioning device, which works in single speed as a tensioner, and with gears it will hold the axle in a fixed position, and allow the rider to choose the wheelbase in a 25mm extent.
All frames have the new internally relieved milled head tube, made from one piece of steel, which has larger outside diameter for good looks and a nice big interface with the lower and upper tubes. It is also 100% resistant to ovalising due to very thick walls and hardening process.
The Suburban and Streetleegal frames feature ultra short chainstays (very popular at the moment) but due to special shape around BB area they can still accomodate fairly large tires even on 26" wheels in the shortest CS position.
The Suburban and Streetleegal frames our exclusive ultra adjustable brake pivot system, that allows optimum pivot positioning regardless of wheel size and axle postion.
