Why this bike wins here

Spinfinity Ultra is rolling, with 8.2 m of climbing per kilometre, the kind of course where aerodynamics usually counts for far more than low weight. The Specialized S-Works Tarmac SL9 is an all-round frame. Disc or regular wheels is a close call: the Shimano DURA-ACE C99 + Disc is 4.8 s faster than the SwissSide HADRON Ultimate 650, but 0.34 kg heavier.
