Y1Rs Size Calculator

To figure out your Y1Rs size take your previous bike and take the following measurements:

A = from the centre of the bottom bracket to the centre of the saddle rail (not the seatpost clamp, let alone the surface of the saddle!)

B = from the centre of the saddle rail to the centre of the handlebar

C = from the centre of the handlebar to the centre of the front wheel hub

D = from the centre of the front wheel axle to the centre of the bottom bracket

E = from the wheel axle to the centre of the saddle rail
