Victory in the 2010 Tour de France and three consecutive wins at the Tour of Flanders reveal the true intentions of the Tarmac. In summit finishes and sprints, where individual grams and tenths of a percent of stiffness count, the Tarmac rider is driven by speed and the thrill of competition.
WHAT High modulus carbon frame made
from our most advanced carbon
WHY Gives our Tarmac the highest stiffnessto-
weight ratio on the market, which
makes for an absurdly light and fast bike.
HOW Divides frame into four monocoque
sections—with carbon fibers running
continuously from tube to tube within each
section—for more precise optimization
of tubes shapes, sizes, and joints.
Tapered Head / Steer Tube
WHAT Strategically designed head tube/steerer
assembly that tapers from 1-1/8” at the top
to 1-1/2” at the crown.
WHY Increases strength and stiffness for greater
HOW The wider base creates a naturally stiffer
junction, and the gradual transition of
carbon fiber from top to bottom eliminates
the potential for weak spots due to sharp
angles (carbon is at its best when it keeps
a smooth line).
WHAT Performance-optimized frame design,
featuring innovative structures like
our proprietary one-piece chainstay/
BB, internal ribbing, and hollow carbon
dropouts and headset cups.
WHY Optimizes weight and stiffness in every
part of the frame for greater acceleration,
efficiency, and handling.
HOW The one-piece chainstay/BB design
resists deflection under extreme
pedal loads for improved power
transfer. Internally raised ribs at the
BB and head tube use optimized
fiber alignment to increase stiffness.
And hollow dropouts and headset
cups cut weight to a minimum.
WHAT Entire Tarmac family borrows
technologies from the high-end,
Pro Tour-winning SL3 and SL2.
WHY Increases performance and overall value
in every Tarmac we make. Allows all riders
to enjoy technology exclusively found
on S-Works level bikes just a couple
HOW Our Pro and Expert level bikes use the
same SL3 construction as our S-Works
models, but feature a different carbon
layup. The Comp and Elite bikes share
technology like triangulated seatstays,
even using the same molds as our
