What are track, bmx, and mtb competitors in Cycling?

Section 4: Players & Officials

Grand Tours: 8 riders per team. Each rider has a designated role: general classification (GC) leader, sprinter, domestique (support rider), climber, rouleur (flat specialist), or road captain.
One-day races: Typically 7 riders per team in WorldTour events. Smaller teams (4–6) in lower-category races.
Team roles: Domestiques protect the team leader from wind, chase breakaways, fetch water bottles, and pace the leader on climbs. Lead-out trains are multi-rider formations that deliver the sprinter to the final 200 m at maximum speed.
Directeur sportif: The team manager who follows the race in a team car, communicating tactics via radio to riders. Radio communication has been a subject of debate, with some races (e.g., certain Classics) trialing radio-free racing.

Track team events: Team sprint: 3 riders (men) or 2 riders (women). Team pursuit: 4 riders per team. Madison: teams of 2 riders.
BMX Racing: Individual competition. 8 riders per gate start in motos and knockout rounds.
BMX Freestyle: Individual competition. Typically 9–12 finalists in the Olympic format.
Mountain Bike: Individual competition across all disciplines. Team relay event added for XCO format (mixed gender, 4 riders).

The commissaire panel is the officiating body for all UCI-sanctioned events. Its structure varies by race level:

President of the Commissaires' Panel (PCP): Overall authority on all regulatory matters during the race. Makes final decisions on protests, sanctions, and classifications.
Finish Judge: Determines the order of finish using photo-finish technology. In road races, the photo-finish camera captures images at 2,000 frames per second.
Timekeeper: Records official times using transponder-based timing systems (e.g., MyLaps or similar). Transponders are mounted on the bicycle fork or frame.
Race Director: Responsible for the operational management of the race, including the motorcade, road closures, and course safety. Works in conjunction with the PCP.
Moto Commissaires: Positioned on motorcycles throughout the race to observe rider conduct, monitor breakaway gaps, and report infractions via radio to the PCP.
Anti-doping officers: Conduct in-competition testing. Selected riders (stage winner, race leader, random selection) are notified immediately after the finish.
Equipment inspectors: Check bicycles before, during, and after races for weight compliance (6.8 kg minimum), frame dimensions, and technological fraud (motor doping) using tablet-based magnetic scanning devices or thermal imaging cameras.
