Haarlem, the Netherlands based manufacturer of radical aluminum mountainbike frames. Individually hand built by Edward Hagen - a successfull marathon speedskater in his former career.
Most famous Rafty is their boom-tube model: the Funnel. The headtube was connected with the the seattube through one very fat tube and the Funnel has an e-stay tail out round (Funnel AS) or square tubing. Three additional tubes reinforced the the boom tube front.
Raftys can be considered rare, as they have been made during a span of only 3 years in the mid 90s.
