Hobie 18 Main Traveler Ball Bearing Set
Hobie 18 Main Traveler Ball Bearing Set includes two traveler ball bearings (#50-61850000), plus one 2″ cotter pin (#50-8060121).
This was the original stock set up for the Hobie 18 main traveler car, then Hobie switched to one ball and one cylinder and now Hobie just sells cylinders. The cylinders do last longer but they do not slide as quickly as the traveler ball. Hobie has stopped production on these traveler balls.
