2002 Trek Technical Manual
For 2002
No change has been made to this frame platform since
its introduction in 2001.
Geometry
The Bruiser frame design is ideal for quick action and
fast maneuvering. It's nimble for slalom racing or dodg-
ing urban obstacles. It's balanced for airtime in either
environment.
Ride
The Bruiser has the frame strength and rigidity nec-
essary for thrash riding. Think of this as a multi-speed
BMX bike for adults.
Frame details
The Bruiser uses Alpha aluminum frame technology,
but with an emphasis on strength instead of low weight.
An ultra-beefy, 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 gusset under the head
tube.
Full top tube cable routing keeps the cables out of the
muck for friction free shifting and braking.
The Bruiser frame uses a special dropout to accommo-
date a disc brake adapter. This adapter provides mount-
ing for an International style rear disc brake.
