OPTIMAL FRAME CONDITIONS

The „corratec Pro Size System“ is the optimal way to customise a racing bike. Development of the „corratec Pro Size System“ had its beginnings in professional racing and was further refined together with the professional cyclist Harald Morscher and the legendary Italian frame constructor Mauro Sannino. Its characteristic feature is a variable frame size system which guarantees optimum seat position for every cyclist independent of their build and length of their legs. Five frame sizes with differing sloping heights guarantee that persons from 1.50 metres to 2.00 metres tall can always find the optimal riding position on the bike. 

> The frame size is defined by the length of the top tube
> The traditional frame height now only functions as a reference point so as to more easily define the frame size
> The length of the top tube is measured at the height of the front end to exclude any mismeasurement due to spacers
> The corratec Pro Size System guarantees optimal seat position
