This Super Skinny Racer Is Almost Entirely Carbon Fiber  Okay,
so it's not as light as the world's lightest, but TriRig's12.9
pounder is still pretty damn light. Crafted out of tough carbon
fiber, the his model's made for triathlons—so it's as
aerodynamic as it is pillowy.  The Ultra Light Tri Bike has
every possible bit of hardware—from saddle clamps to brake
levers—either stripped away or lightened as much as TriRig could
pull off. The result is pretty gorgeous, and we imagine would be
a godsend for an athlete who had to haul the thing around. No
word on pricing, but given the $45,000 price tag of the last
TriRig cycle we covered, expect something in this neighborhood.
