Pro bike: Joanna Rowsell’s Colnago K.Zero

Wiggle-Honda's sleek TT machine

Joanna Rowsell (Wiggle-Honda) went into the British Time Trial Championships as defending champion, finishing 6th on the hilly, technical course behind Emma Pooley. She and her teammates Elinor Barker (4th), Laura Trott (5th) and Dani King (8th) were all aboard their team issue Colnago K.Zero time trial bikes.


The K.Zero is a sleek TT frame, its tubes shaped using NACA aero profiles and its stem and top tube completely flush with each other, sloping down towards the seat tube. External cabling costs seconds and that’s been kept to a minimum on this bike. That philosophy is carried through to the TRP brakes, which are hidden behind the fork and on the chain stays.

Rowsell runs her pads with a gap between them, which can help aerodynamics as well as bike handling:

Rowsell rides a size S frame, featuring a 51cm seat tube and 52cm top tube. She hasn’t gone super narrow on her bar extensions, preferring a wider stance, which can be both an aero benefit, depending on the rider, and help with stability and handling.

Her bike as pictured was set up with an Campagnolo Bora Ultra TT disc and an Ultra front, although she was planning on swapping to an deeper Ultra Two for the race, provided her teammate came back in time. The team ran Vittoria Corsa CX tubulars (23-28), ideal for grip and speed on this course.

The hilly nature of the 21km course saw many riders opt for rear cassettes with a big range, and Rowsell was no exception. She rode a 53/39 front chainring combination with an 11-speed 11-27 rear cassette. All Campagnolo Super Record mechanical with not a hint of EPS electronic in sight.

Other highlights of Rowsell’s rig include Speedplay pedals, an SRM Power Control 7 (although the SRM unit was absent) and Fi’zi:k bar tape.

An srm power control 7 computer was mounted on the bars but no srm unit attached:
