Too fast for the UCI, but perfectly legal for triathlon, the Shiv
is ridden by competitive athletes looking for the most efficient
power transfer, most aggressive position, and least drag. Whether
long or short-course triathlon, the Shiv is the weapon for those in pursuit of
nothing less than the fastest bike split and next personal best.
WHAT Radically shaped carbon tubing engineered
to create advanced aerodynamic structures.
WHY Ensures the lowest drag possible from
leading to trailing edge.
HOW We design our own airfoils for the unique
geometry and angles of the Shiv, based
on computational studies and handson
research in the wind tunnel. By
studying the aerodynamics of the entire
3D system (bike and rider) and seeing
how airflow in one section affects the
next, we can optimize our airfoil shapes
to more efficiently minimize drag.
WHAT All components designed together
for complete system integration.
WHY Allows us to make a stiffer and more
HOW Every component—from the brakes, head
tube, and stem, to the bottom bracket and
crankset—is designed from the ground
up to work together for the intended
Tapered Head Tube/
WHAT Strategically designed head tube/steerer
assembly that tapers from 1” at the top to
1-1/8” at the crown.
WHY Increases torsional strength and stiffness
for greater steering precision, while
HOW Keeping the top narrow minimizes
frontal area, and the wider base creates
a stiffer junction. The gradual transition
of carbon fiber from top to bottom
eliminates the potential for weak spots.
WHAT A precise frame sizing method that’s based
on effective stack (X) and reach (Y) to the
WHY Allows the rider to determine their
appropriate bike size and more closely
replicate their fit from bike to bike,
rather than relying on traditional top
tube measurements. A fine-tuned fit is
especially important for triathlon bikes,
where the rider must hold a fixed position
for an extended period of time.
HOW Measures the height of the aerobar pad
above the bottom bracket (effective
stack) and how far the pad sits in front
of the bottom bracket (effective reach).
