How the Sticker Works
1
Two stickers per bike — one on the frame, one on the fork. Each carries a unique model ID code cross-referenced against the UCI approved database.
2
Permanent & indelible — applied under clearcoat during production. Only the manufacturer can reapply; riders and teams cannot self-apply.
3
Always visible — must not be hidden (e.g. under bottom bracket). Seat tube is the standard approved position for the frame label.
4
Position is pre-approved — the exact zone is defined per model at the end of the UCI approval process.
5
Height category label — a separate 25 mm roundel on the top tube for TT & pursuit events. Rider-applied and not permanent.
6
No sticker = no start — commissaires perform spot checks. A bike without a required label is refused at the startline.
