TECHNOLOGY STORIES BIKE INFO, GEOMETRY ... - Vintage Trek

For 2002
Navigator frames remain unchanged from 2000.
Geometry
The Navigator is designed with geometry which
puts you in a full ‘heads up’ position. The dimensions
may look a bit odd on paper, but there
is a reason; we designed these frames from the
ground up to use suspension seatposts and adjustable
stems.
Ride
For the recreational cyclist, these bikes are an
epiphany. Instead of focusing on race qualities like
carving turns, or power uphill, the Navigator’s
first feature is comfort. Some afficionados will
point out that an upright position is not aero,
and is therefore inefficient. We’ll point out that
aerodynamics only really become important above
20 MPH. Or that if you are off the bike
because your back hurts, aerodynamic efficiency
isn't worth much, regardless. Furthermore, the
Navigator rider is not trying to beat the clock,
they just want to have fun.
Riding a Navigator, you will enjoy these bikes
for anything from a spin around the neighborhood
to commuting and day tours. The comfort features,
like suspension fork, sprung saddle, or seatpost are all
tuned to react at low bump forces, so you don’t have
to be going really fast or hit big bumps to enjoy their
benefits. The smooth tires make these bikes pretty fast,
but the large footprint also makes them stable on dirt
footpaths or Rails-to-Trails tours.
Frame details
The Navigator uses Alpha aluminum frame technology.
Designed for suspension seatposts and adjustable
stems, this frame has a unique look to it. The seat tube
is short compared to other bikes because a suspension
seatpost has a section which cannot be lowered into the
frame. This means the normal seat height is quite a
ways above the top tube. Meanwhile, this rider wants
to sit upright. If a suspension seatpost were put on a
‘normal’ frame, the head tube would be too short to
position the handlebars for a comfortable, bent-elbow
position.
Navigator bikes have 2 water bottle mounts, except
the 14.5 and Ladies frames. These frame sizes do not
have enough seat tube to allow a water bottle mount
to be used.
Fit Information Reminder
When considering the "Rider Height" portion of the
Fit information on each page, bear in mind that we
made these fit estimations with the stem at its highest
point. With Ahead stems, that means all the spacers
were under the stem. With quill stems, the handlebars
reach their maximum height with the stem pulled up to
the minimum insertion line. With adjustable stems, it’s
calculated with the stem at a 40 degree angle. Lowering
the bars, or changing the parts, or changing the stem
angle, changes the fit of the bike as well as its Rider
Height. Primarily, if you lower the stem, the bike will fit
a smaller person. If you make the stem more upright, it
will also make the bike fit a smaller person.
