2002 Trek Technical Manual
For 2002
The STP was introduced in the 2000 model year. The
frame is unchanged.
Geometry
The STP uses Trek's race-proven Pro Geometry. Sizes
are only offered down to size M because smaller frame
sizes would not have room for the rear shock.
Ride
Today's race courses are generally smoother, and the
racers fitter, than in the past. Racers have very strong
legs, which can effortlessly absorb a lot of terrain.
Racer's don't need a lot of suspension, instead looking
for low weight. Only one bike offers exactly what these
racers need. The STP is a racing suspension bike for
today and the future.
The STP frame is lighter than some racing hardtails.
The suspension reacts only on the biggest hits, or when
pedaling in the saddle. The rest of the time the STP feels
like a very light, OCLV hardtail. In this capacity, the
frame offers outstanding pedaling efficiency.
The STP design feels like a hardtail much of the time,
but without the jarring of rigid stays. It climbs well out
of the saddle, it smoothens small bumps for comfort,
and has improved traction. The traction advantages are
full-time, both climbing and braking hard. This combi-
nation makes the STP ideal for racing.
Frame details
The STP uses OCLV frame technology. Inside the
head tube, bonded aluminum `top hats' support the
headset cups. Rather than a continuous tube, the top
hats allow a significant weight reduction. Mechanics
need to exercise care when removing headset cups to
make sure a removal tool is inside the top hats, not
outside where hammering can damage the frame.
Full top tube cable routing keeps the cables out of the
muck for friction free shifting and braking.
When the rear wheel hits a bump, the frame must
flex. Carbon composite is the ideal material for this
application, having an almost infinite fatigue life. In
addition, our engineers designed the STP so more than
just the chainstays flex; the down tube also flexes. The
frame is designed as a system, not just as an added
shock.
The fittings, like dropouts, seatstay yoke, and shock
mounts, on the STP are all forged aluminum. Forging
provides the highest structural integrity, while the low
density of the aluminum keeps the bike light.
The STP seat tube uses a fiberglass internal sleeve to
prevent galvanic corrosion of the seatpost to the frame.
Do not grease the seatpost, or the seatpost clamp may
not provide adequate clamping force.
The STP design incorporates a special, built-in chain-
stay protector to resist chainslap damage to the carbon
chainstays.
The STP does not have fittings for disc brakes, which
could transmit heat into the carbon stays.
All STP bikes have 2 water bottle mounts.
