The sprint or match sprint is a track cycling event involving between two and four riders, though it is usually run as a one-on-one match race between opponents who, unlike in the individual pursuit, start next to each other. Men's sprint has been an Olympic event at every games except 1904 (which had races at seven different distances) and ...
The Eiviestretto is a backwards-ridden vehicle with the rider's head pointed in the direction of travel. The rider lies on his back, using a mirror to navigate. The design is based on Eivie III from Damjan Zabovnik, with several improvements. [3] In 2016 Russo improved his record to 92.43 km (57.44 mi) on a bike he designed himself.
On land, the speed record registered by a rider on a 200-meter flying start speed trial was 133.28 km/h (82.82 mph) by the Canadian Sam Whittingham riding the Varna Tempest, a streamliner recumbent bicycle in 2009, [19] at Battle Mountain, Nevada. His record has been surpassed by 0.5 km/h by Sebastiaan Bowier of the Netherlands in 2013 setting ...
From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
The team sprint (also sometimes known as the Olympic sprint) is a track cycling event. Despite its name, it is not a conventional cycling sprint event – it is a three-rider team time trial held over three laps of a velodrome. The riders use a standard track bicycle which are single-speed with no freewheel or brakes.
To achieve the speed, conditions were simulated whereby Burford was "towed" until he reached 100 mph (160 km/h). The towline was then "released", and he was left to pedal. Bursford's speed was attained during a half-minute interval with him reaching 60 mph (97 km/h) in two seconds at the start of the attempt. [ 4 ]
Their design is strictly regulated by the UCI, the sport's governing body. Specialist time trial bicycles are used for time trial events. Bicycles approved for use under UCI regulations must be made available for commercial sale [ 9 ] and it is commonplace for amateur cyclists to own bicycles that are identical to those used to win major races.
This design can be much stronger than traditional axles, which are commonly only 8 mm, 9 mm, 9.5 mm, or 10 mm in diameter. [ 3 ] (found on higher end BMX hubs and some mountain bike hubs) Since the 1980s, bicycles have adopted standard axle spacing: the hubs of front wheels are generally 100 mm wide fork spacing, road wheels with freehubs ...
