Orica-Greenedge sports director Matt White says that both Jack Bobridge and Rohan Dennis have the ability to smash the current World Hour record.

Bobridge will make his record attempt at the Darebin International Sports Centre in Melbourne on January 31. Dennis will follow suit at the Velodrome Suisse in Grenchen, Switzerland on February 8. Austrian Matthias Brandle holds the current record at 51.852km.

"It's a really good idea. Both of them have the ability to smash the record," White told Cyclingnews. "Those two definitely have it in them to put in a fair bit of distance [on the record]. It will be a very good a marker. They are obviously [track] specialists. Their ability on the track will certainly serve them a lot of good. I think Rohan will go further."

But he doesn’t think either men have the ability to hold off the best time trialists, such as Wiggins, Martin and Cancellara.

"Rohan and Jack are obviously world class guys; but I think they want to get ahead of the curve there before a Wiggins or a Cancellara or a Tony Martin has a big go at it.”

"Those guys have made it pretty public that the earliest any of those big hitters are going to go for the record is …. I think Wiggins was saying in the summer.”

White said that there was initial plans for Michael Hepburn to make an attempt, but that will no longer happen due to his race schedule.

"There was a little bit of talk of it, mainly by our sponsors," White said. "They were pretty keen. But he won't be attempting it. In his [road race] program, it just didn't fit.”

"I am pretty sure he is of the same ability as Rohan and Jack. But what we have planned for Hepburn didn't align with going for the hour record in this season.”
