FX (Fitness and Exercise)
New for 2002
The 7200 FX and 7500 FX use the same framee as
in 2001, our Alpha hybrid frames. The 7700 FX uses a
new, faster and more aggressive design for those want
to go faster, farther, and more powerfully. In addition to
a more forward position, the 7700 FX also uses an alpha
SL frame for reduced wieght and increased liveliness.
Geometry
The FX bikees use a hybrid frame, but with a lightweight
rigid fork (not on the 7200 FX). This provides a
slightly more spirited ride that’s fun and maneuverable
at higher speeds. Yet it’s stable so you don’t have to
focus solely on the road or its obstacles.
Ride
The FX bikes offer nimble handling that makes them
ideal for faster all-round riding or fitness training.
We have to give credit for this concept to the cycling
public. We were out riding when we saw riders moving
fast and light in a comfortable, upright position. We’ve
seen these riders scooting around town for work or a
cappuccino, as well as all across the country cranking
hard on multi-day tours.
Both the Alpha and Alpha SL frames offer outstanding
pedaling efficiency so you can crank up hills and go
the distance. The exceptional frame rigidity also gives
the FX its ‘riding on rails’ cornering ability.
Just because you like to sit up doesn’t
mean you can’t have fun; the FX is fast
and lively.
Frame details
The FX frames use Alpha, Alpha ZX,
and Alpha SL aluminum frame technology.
With these frames, an oversize down tube
creates a rigid structure between the bottom
bracket and head tube, for frame
stiffness and strength. Speaking of frame
strength, we even added a big butterfly
gusset under the head tube.
The fittings, like dropouts , are forged
aluminum. Forging provides the highest
structural integrity, while the low density
of the aluminum keeps the bike light.
FX bikes have 2 water bottle mounts,
except the 15L and 17L. These frame sizes
do not have enough seat tube to allow a
water bottle mount to be used.
