A type of road bicycle racer who specializes in rolling terrain with short but steep climbs. Ideal races for this type of rider are the one-day classics in spring. These races are characterized by hills that are a 10–20% grade and 1–2 km long; examples include the Liège–Bastogne–Liège, the Mur de Huy in the Flèche Wallonne and the Manayunk Wall in the Philadelphia International Championship. The physique of this type of rider allows them to escape from the peloton through quick bursts usually with the assistance of a teammate. Examples of such racers include Philippe Gilbert, Paolo Bettini, Danilo Di Luca and Peter Sagan, who are able to sprint their way up the shorter climbs to win a stage or a single-day race.
