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

New for 2002
The 2002 line shares the same frame as
the 2001. Why change the bike that won
the Tour de France?
Geometry
The geometry of the OCLV 110 and 120
frames are basically the same, except the
Superlight uses a special internal headset
bearing which requires a longer head
tube. Both bikes are built for classic road
racing feel and performance. Angles, top
tubes, and bottom bracket height fit the
demands of racing. Comfort, pedaling efficiency,
and handling are all optimized for
long stage races.
Ride
The first thing most riders notice about
OCLV is how incredibly light these bikes
feel. They simply “disappear beneath you”.
You feel like you’re flying around, with
your legs spinning.
In terms of handling, these frames are
full race. The frame rigidity makes an
OCLV bike corner like it’s on rails.
Comfort is also an outstanding feature.
Despite a fairly stiff frame feel, OCLV road
bikes absorb a lot of road shock. Part
of the secret is carefully designed carbon
layup, which allows the engineer to separately
control vertical and horizontal flex
patterns. The other secret is that frame
joints made from carbon lugs can flex.
Metal joints cannot flex like this, or they
risk fatigue failure.
Frame details
OCLV road bikes have large diameter tubes
for excellent frame rigidity. By stiffening
the bottom bracket area, these frames pro-
vide efficient transfer of your pedaling power
to the rear wheel. No energy is wasted.
Acceleration is excellent. Of course, the
exceedingly low weight helps here, too.
The fittings on the OCLV road bikes are all
forged aluminum. Forging provides the highest
structural integrity, while the low density
of the aluminum keeps the bike light.
All OCLV road bikes have 2 water bottle
mounts.
FOR THE MECHANIC
Superlight headset
The OCLV 110 uses a proprietary headset
system. See the bck pabes of this manual
for maintenance details.
Removing Headset Cups
When removing a headset in an OCLV frame, make
sure the headset removal tool is engaging the headset
cup. OCLV framesets do not utilize a continuous headtube,
but instead use two short inserts to support the
headset cups. If the headset tool is outside the insert
rather than inside the insert and pressing on the cup,
frame damage can result.
The seat tube of our OCLV road bikes uses a fiberglass
internal sleeve to prevent galvanic corrosion of the seat-
