"Lance Armstrong may have his eye on yet another record: the hour.
Armstrong made a visit to the ADT Event Center velodrome Sunday to conduct tests on two different bikes. He was accompanied by Johan Bruyneel, Steve Hed, Chris Carmichael, a video crew with boom mike and a still photographer, among others.
He made a half-dozen runs of roughly ten laps each, first on a nearly stock Trek F1 track bike equipped with 28-spoke wheels, drop bars and, of course, an SRM power meter.
Then he switched to an aero bar-equipped Trek TTX time trial bike with Hed-designed Aeolus 6.5 deep-section wheels and SRM, and traded his Giro Ionos helmet for an Advantage aero helmet.
Armstrong’s early lap times on the 250-meter track were in the sub-19-second range, good for better than 29 mph. He looked relaxed and smooth. When he switched to the TTX time trial machine he quickly shaved a second off his lap times — with no appreciable increase in effort — bringing his time to 17.7 seconds per lap, and a speed of 31.6 mph.
After each of the brief sessions, Armstrong would consult with his advisers before heading back out. His times were recorded and called out to him as he passed.
Given that he tried not one, but two different bikes, Armstrong may have set his sights on both Ondrej Sosenka’s old-tech hour record of 49.7 km as well as Chris Boardman’s 56.375km “Best Hour Performance.”
Last week, Armstrong recently posted a photo of the SRM-equipped Trek track bike on his Twitter account. The photo was captioned, "Why not?" But Armstrong did not respond to his many Twitter followers' speculation about a possible hour record attempt."
