One Twenty 600 2026 Transition Frames The Jack Rabbit from CSTDescription The all rounder is back. The ONE TWENTY 600 is the short travel trail bike that's ready to ride to whatever you want it to. It'll breeze down tough descents thanks to our progressive geometry and 130 mm of well controlled travel thanks to a Marzocchi fork and shock, but it'll still eat hills and fast singletrack for breakfast. Add in the crisp shifting of a 12 speed Shimano drivetrain plus powerful 4 piston front and 2 piston rear brakes,
