Hour record http://en.wikipedia.org/wiki/Hour_record(- -)
UCI hour record[edit]
The hour record is usually attempted by road cyclists towards the end of their career. This is true of Miguel Indurain (Spain), Francesco Moser (Italy), Chris Boardman (Great Britain) and most recently Jens Voigt (Germany).
Eddy Merckx said his hour record attempt was "the hardest ride I have ever done". It was set in 1972 in Mexico City at an altitude of 2,300m (7,550 ft).
In January 1984, Moser set two records, the second being 51.151 km (31.784 mi). This was the first noted use of disc wheels, which provided aerodynamic benefit.
In 1993 and 1994, Graeme Obree, a Scot who built his own bikes, posted two records with his hands tucked under his chest. In 1996, Boardman set a record using another position pioneered by Obree, his arms out in front in a Superman position. Both were considered controversial by the UCI, and while the records were allowed to stand, the positions were banned. Obree and Boardman made several attempts to top the previous record.
With the increasing gap between modern bicycles and what was available at the time of Merckx's record, the UCI established two records:
_________________________________________________________________________________________________________________________
the UCI Hour Record (which restricts competitors to roughly the same equipment as Merckx, disallowing time trial helmets, disc or tri-spoke wheels, aerodynamic bars and monocoque frames) and
the Best Human Effort - sometimes termed the UCI "Absolute" Record.
_________________________________________________________________________________________________________________________
All records since 1972, including Boardman's 56.375 km (35.030 mi) in 1996 were downgraded to Best Human Effort. In 2000, Boardman attempted the UCI record on a traditional bike, and rode 49.441 km (30.721 mi), topping Merckx by 10 m (32.8 ft) - an improvement of 0.02%.
In 2005 Ondřej Sosenka improved Boardman's performance at 49.700 km (30.882 mi) using a 54×13 gear. At 200 cm (6 ft 6¾ in) tall, Sosenka used an unusual saddle position and a small vertical frame height to stay within UCI regulations.[2] Sosenka failed a doping control in 2001 and then again in 2008, the latter resulting in a career ending in suspension which puts in doubt the validity of his record.
Unified rule change[edit]
Jens Voigt during his successful attempt in September 2014
In 2014 the UCI unified the two classifications into a single classification in line with regulations for current track pursuit bikes. Records previously removed for Chris Boardman and Graeme Obree would be returned, however the current record would remain at 49.700 km set in 2005 by Ondrej Sosenka, even though that is not the farthest distance.[3][4] Under the new regulations riders may use any bike allowed by the UCI standards for endurance track events in place at the time of the attempt.[5][citation needed] Riders are required to be part of the Athlete Biological Passport Program.[6]
Following the change in the rules, German Jens Voigt became the first rider to attempt the hour, on 18 September 2014 at the Velodrome Suisse, Grenchen, Switzerland.[7][8] He set a new record of 51.115 km, beating the previous record set by Sosenka by 1.4 km.
