More about Unknown PS1 Fixed Gear Bike
The Unknown PS1 takes its shape from pursuit track frames: the round down tube gradually flattens towards the bottom bracket, giving the 6061-T6 aluminium frame its distinctive profile. A carbon fork on an aluminium steerer and taped bullhorn bars complete the front end.
The drivetrain runs a 48T chainring on 165 mm cranks and a 17T fixed cog on a flip-flop rear hub, with a single-speed freewheel included. Front and rear brakes come fitted. The PS1 is available as a complete bike in Green, in sizes 54, 57, 59 and 62.
