At launch Specialized is just offering
one complete build for men and
one for women, the S-Works bike costing £9,250, with a full
complement of Dura-Ace R9100 components and Roval CLX50 wheels and,
for the first time, its very own S-Works dual-sided power
Frame weight is up a little, 733g to 800g, and 338g for the
fork, but this S-Works model tickles the scales to just 6.66kg, so
is well below the UCI's 6.8kg weight limited if such a thing
Compare that to an S-Works Tarmac Rim at 6.36kg and the
difference is negligible, especially when you factor in the much
improved braking performance of the latest R9170 disc brakes with
their funky disc rotors.
So that's just a 300g weight difference between the rim and disc
brake Tarmac, and with a power meter included! Oh yes, Specialized
has also unveiled
its own range of power meters, and its top-end S-Works
dual-sided power meter is fitted as stock to the bike.
The geometry of the new bike is largely identical to the rim
brake Tarmac, only the chainstay length is fixed at 410mm rather
than varying from 405 to 410mm depending on frame size as part of
Specialized's improved Rider-First Engineered approach to frame
design. Specialized has also minimised the aero impact of disc
brakes, and it says both bikes provide identical drag figures.
It's also available as a
frameset costing £3,250 with a choice of paint jobs. So as
always we'll be offering the option to build your dream bike to
your specifications, and of course perfectly fitted.
