Pure individuality:
good value for money, exact, at any time.

Already in the standard version, a bicycle with ISA head tube
can be adjusted to two different lengths. As there are no parts
to be replaced, the costs for the individual adjustment of the
seat position stay low. For an even more exact adjustment of
the seat position to the cyclist's needs, the bicycle manufac-
turer offers additional ISA-Plates. These enable adjustments
of the frame length in steps of 2.5 millimetres. The bicycle
manufacturer uses his sale network to deliver the ISA-Plates.
Dealers who offer a bicycle with ISA can adjust the seat posi-
tion to the individual wishes of the cyclist. The frame length
can always be adjusted, also after the purchase of the bicycle.
