To satisfy the need of every rider, the CrMo frame.
It is available as XXL (560mm toptube) and XL (540mm toptube).
The XXL and XL are available with a OPC (regular US) bracket with 29.2mm seatpost tube.
Their specs are identical to the aluminum frame, 75 degreed headangle and a short chainstay for superb rolling over jumps or powering out of turns.
The downtube has the familiar oval shape that makes the looks of ONE different from others. The chainstaydropouts are CNC machined and the chainstaytube itself has a rectangle shape.
3kg (6.6 lbs) - a lot of frame for a very low price !
