Since the Hour Record bike regulations were simplified by the UCI in May 2014, there has been a rash of attempts on the title – and among those leg-burning, all-out efforts, we've had some gorgeous bikes to drool over.
So far we've covered the machines of Jens Voigt, Matthias Brändle, Jack Bobridge, Rohan Dennis, Dame Sarah Storey and current record holder Alex Dowsett.
This year, we're looking forward to seeing Sir Bradley Wiggins take on the Hour on 7 June, while Tony Martin has also expressed interest. There's always the hope that we'll finally see Fabian Cancellara have a go too.
