Yeti
Cycles is well established as one of the pioneers of mountain bike
manufacturing and design as well as racing heritage. A quick scan of their
previous team rosters includes some of the most influential names in mountain
bike racing history such as Missy Giove, Myles Rockwell, April Lawyer, Tara
Llanes and Nathan Rennie. Their recent partnership
with Fox Racing Shox and corporate restructuring as well as
one of the most comprehensive racing development programs in the US regional
and national series means that they have remained at the forefront of frame and
suspension technologies … new products and announcements from Yeti get a lot of
attention in the bike industry, especially from the manufacturers’ teams they
are competing against.
When Yeti first released it’s current DH race machine, the
303, in 2005, with it’s very intricate and slightly intimidating dual rails on
which the rear triangle slid in a controlled linear movement, reaction to the
design was at first lukewarm with skepticism about the system’s inherent
reliability and ease of maintenance. These fears were proven largely without
merit and the critics were quickly silenced by the bike’s prowess and performance
in race series across North America and on the World Cup circuit.
Yeti design engineer Peter Zawistowski explains the
company’s affinity for this unique design feature: “A linear rail essentially
has the same mechanical function as an infinitely long link, but is unique in
that it comes in an extremely small and stiff package. This opens the door to new suspension designs
as we are able to implement the function of a very long link within the
confines of a frame while keeping the system very stiff.”
Yeti also has the advantage of developing their suspension
designs with input from the suspension gurus at Fox. “We’re constantly talking
back and forth. We’re very tight with those guys which is awesome.” It is a
testament to the success and Yeti’s faith in the rail system that it has found
it’s way onto several new prototype bikes currently being tested by their
factory riders.
Two of those prototype bikes, on display for the public for
the first time, were at the 2008 Sea Otter Classic in Monterey, California and
provide a glimpse of some exciting things to come from Yeti.

The 303-7 is a 7-inch travel, lighter duty downhill race
frame that retains one of Yeti’s trademark rails in a position in front of the
bike’s seat tube. It also showcases Yeti’s extensive use of leading CNC
technology and the machining, which even in its unpolished, prototype finish,
is immaculate.

Zawistowski, thinks one of the most important aspects of
this particular frame design is the quality of the travel. He claims the bike’s
rear wheel travels rearward in a linear movement as opposed to an arc which
makes the bike smoother over square shaped obstacles. “The entire path of the
wheel is rearward. It’s a more efficient transfer of force from a square bump
or hard lip.”

Another exciting new frame certain to turn heads is the
“Slope Style,” or 303 R-SS. Yeti’s foray into this genre of frame was
inevitable with the popularity of slopestyle
park riding and the demand from riders/consumers for a smaller, tighter
freeride bike capable of a variety of activities, from hucking to dirt-jumping
to trail-riding … essentially a do-all
play-bike, with relaxed geometry, low standover height, 4 to 6 inches of
travel, and burly construction. The success of pioneering bikes like the
Transition Bottlerocket have seen a variety of manufacturers produce a
“slopestyle specific” bike and it was only a matter of time before an industry
leader like Yeti jumped on board.

The frame utilizes a linear rail in order to control the
shock rate for a total of 5.4 inches of travel.
With this particular design the shock does not rotate during its
compression resulting in a very efficient system. Yeti/Fox rider Mikey Haderer had a chance to
ride and test the prototype Slope Style bike while training with the Yeti
team’s Norcal Racing Development Program earlier this spring and shared his
initial impressions.
“What really impressed me was the lateral stiffness of the
frame and how active the suspension was while remaining a good pedaling bike.
Definitely the most memorable aspect to its ride is it’s solid and stiff rear
end. The bike just turns on rails.”
In addition to these two exciting new designs, Yeti is also
working on a new economical long travel DH racer, tentatively referred to as
the 303-RDH. This bike is not intended to replace the 303 but provide a less
expensive alternative with many of the same attributes and benefits.
The new prototypes will be raced by team Yeti throughout the
season in order to test and optimize the designs. “This is huge for us as we are continuously
getting feedback from racers at the word cup level,” says Zawistowski.
Yeti has not released any official specs on any of these new
bikes but is hoping for a 2009 production release. They have just posted some
teaser photos of their own on the Yeti website; http://www.yeticycles.com/#/photo/
.The white-knuckle set waits with baited breath.
