Rohan Dennis’ Hour Record BMC bike

Rohan Dennis' Hour Record BMC bike

Rohan Dennis’ Hour Record bike: a customised BMC TrackMachine TR01. Dennis used a Shimano Dura-Ace crankset with an SRM power meter. The gear ratio was 56×14. The regular TrackMachine TR01 was designed for optimum aerodynamics within a velodrome, taking advantage of the constant zero-degree yaw wind and lack of crosswind interference. Highlights of the ‘SubA’ aero design include an integrated hinge fork, 3:1 teardrop truncated tube shapes and flow disrupting ‘tripwire’ technology.

The p2p (position to perform) triangle concept stem allowed this aero advantage to be utilized in harmony with varying rider position. The stock bike also weighs just 6.45kg, which BMC has had to increase to 6.8kg to meet UCI regulations.
