New for 2002
BMX continues to evolve, and so do our frames.
Mostly we apply small tweaks and details, but to stay on
top it has to be kept current.
Geometry
Our BMX bikes are designed to satisfy both kids and
their parents. By carefully designing the frame and
components, we make the bikes easier for kids to get on
and ride. At the same time, we provide competition level
performance that’s tested by our Trek BMX Pro team.
Frame details
BMX riding and performance is all about durability.
Check out the hefty dropouts and grind plates on our
bikes. Look at the massive welds joining the tubes.
Notice the strategically placed gussets. What you can’t
see is the carefully selected tubing wall thicknesses, and
the almost endless testing that’s required before a Trek
BMX bike hits the market.
Our Jumping bikes, the TR series, are all built from
rugged steel. These bikes are beefy. Look at the super
heavy-duty head tube. This is to resist headset stretch, a
major problem when the bikes suddenly aren’t airborne
anymore. Both the top tube and down tube intersect the
head tube, making for the strongest possible frame. At
the other end of the bike, we’ve increased the diameter
of the stays to add strength for rear first landings.
Our Racing frame (T.I.) is aluminum for lower weight,
but we still built it beefy for competition. The downtube
is slightly smaller in diameter to allow a slight flex
for excellent handling on the berms, but it's still stiff
enough to land smoothly after jumping a double.
Our Vert series features long top tubes, with short
rear ends. This design provides great balance for those
radical tricks. They’re also heavily built, with thick
tubes and extra gussets.
