How this count works

• The sample is the 3 pros on RACEKIT with rear cages on file — not the whole professional field.
• One line per athlete: the race-day primary. An alternate setup doesn’t get a second vote.
• Brands are counted by identity, not spelling, so ROKA and Roka are one brand.
• Kit comes from public record — race photography, athlete posts, and sheets athletes have claimed and corrected themselves. Sponsorship is noted where known, but a contract isn’t evidence that something was raced.
