Indicate
the distance from the centre of winch drive to the centre of the upper tube in cm, then you will receive an exactly fitting hire bicycle from us on Mallorca (this refers to conventional diamond-frames).
If you are unsure, for instance referring to frames with so-called "sloping"-geometry, go to your bike trader and ask him to measure for you. Point out that you need this dimension for your hire bike from Fred Rompelberg on Mallorca.
Fill in this mid-mid-dimension under “frame size”.
