After decades of virtual silence on the hour record front, (in UCI legal spec at least) there has been a flurry of activity.
Ondrej Sosenka set a new mark in 2005, though a failed dope test has put that result in doubt. Subsequently the flamboyant Jens Voigt made a splash when he announced his retirement and intention to ride the hour. He set a new mark in Germany in September 2014.
Recently Jack Bobridge attempted to set a new record (January 31st), but failed to better the mark set on October 30th 2014, by Matthias Brandle (who took the title from Voigt) of 51.852km.
Rohan Dennis of BMC Racing Team arrived at the Swiss velodrome in Grenchen for his attempt on February 9th, just two weeks after his victory at the Tour Down Under in Adelaide. He finished the hour covering 52.491km and claimed the record, the first time an Australian has held the title.
