Just picked up our second tandem (a used Univega). The guy I bought it from had a little strappy thing that goes over the handlebars and around the seatpost to keep the front fork straight while putting it up on the rack for transport.
Have taken it to a couple of LBS and they were no help... "Don't have any, never seen it before..."
Does anyone know what they are called? Where one might find them online? (In other words, I can't even search for them online (tried a couple of search terms on this forum also) unless I know what they are called.)
