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

Geometry
Introduced for the 2000 model year, the Hilo is a fullfledged
Tri-bike, not a redressed road racer. It has good
steering feel when you’re on the aero bars, even with
the lighter 650c wheels. The very steep seat tube allows
you to open the angle between your thighs and torso, so
you can comfortably stay aero for long stretches. A good
aero tuck is worth a couple MPHs!
Ride
Our engineering staff includes some good triathletes,
and they know how important it is to come off the bike
refreshed and ready to run. So the Hilo is comfortable.
Still, it has excellent efficiency thanks the the Alpha
SLR frame tubing, so it’s very fast.
Frame details
The Hilo has a large, wing shaped down tube and
a thin mono-stay to help cheat the wind. We even
went the extra mile to run the cables inside the frame.
Coupled to a wing-shaped carbon fork, the Hilo really
slices the air.
Although they may not be aerodynamic, the Hilo has
2 water bottle mounts. You can’t go fast if you’re dehydrated.
The Hilo uses Trek’s proprietary Alpha SLR frame
tubing.
