BMC has released full details of Rohan Dennis' customised BMC TrackMachine TR01 bike, which the Australian rider will use for his 8 February hour record attempt.
Despite BMC's claim that the TrackMachine TR01, designed and developed for the Swiss National Track Team, is the most advanced track-specific bike in the world, Dennis' TR01 has been modified at BMC’s Impec Advanced R&D lab to improve its aerodynamics and stiffness.
BMC Switzerland head of product, Stefan Christ, said: "Rohan is a superb athlete and it is our duty to match his athletic capabilities with a bike of that same caliber. Some minor modifications to influence the aerodynamics and stiffness have been made to Rohan’s Trackmachine TR01. We felt these were necessary to ensure that Rohan’s bike is optimised to take on this highly specific challenge."
In a bid for marginal gains, the BMC Impec Advanced R&D lab engineers took an off-the-peg TrackMachine TR01 and upgraded it with a custom-moulded cockpit following the fine tuning of Dennis' position at a training camp in Spain before Christmas 2014.

Dennis is using a Shimano Dura-Ace crankset with an SRM power meter rather than the stock bike's track cranks, with BMC's engineers creating a perfect chainline for the road cranket via specially designed and milled custom-spaced track cogs.
The p2p (position to perform) triangle concept stem allows this aero advantage to be utilised 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.
