Anyone who races track.
Races at the track, even endurance races, are in fact long sprints. We ride fixed gear no brakes which means we have to have a wider range of cadence capability and more strength for mass start races. The larger the gear selected the more strength is required to accelerate to close or open gaps.
And we have standing starts for many of our races including team events and executing a fast start matters. Unlike in a road time trial or team time trial where the standing start is done from a start house with a ramp and the race is much longer rendering the start immaterial to the result. It takes a lot of strength and technique to start a fixed gear bike in a large gear.
Old school philosophy was for road racers to ride fixed gear on the road with the goal of developing strength and leg speed during the strength and adaptation period of the training cycle.
As @
burnthesheep said, track is a specialty with its own requirements. However, strength to weight ratio is an asset in all races at the track. And many UCI grand tour riders got their start at the track such as Wiggins and Cavendish who were also Madison partners and won the world championship.
