The Australian gave the bike its first public viewing through the Instagram channel of bike shop Meesterknecht - Cyclecity Amsterdam. The bike is a stock BMC TrackMachine TR01 with a full 3T aerobar set-up, rather than the usual drop bars, and a pair of disc wheels.
The 3T basebar is perfectly horizontal and the extensions are stacked with around 50mm of spacers, giving a plentiful saddle to bar drop to allow Dennis to achieve a flat-backed aero tuck.
The saddle looks to be a Fizik Arione (the brand sponsors BMC Racing team) while Dennis is also using a Shimano Dura-Ace crankset with an SRM power meter rather than the stock bike's track cranks. Pedals are from Shimano too.
Rohan Dennis will attempt to break Mathias Brädle's Hour Record on February 8. We hope to have more details on his bike at that time.
