As far as I am aware, the Galaxy was considered a decent and popular bike for touring in England. It's prececessor was the Windrush, and the Double Blue was the top of the line model. I think there was another model called the Realm Rider, which I think was a little lower in the hierarchy. Bikes Direct sells some bikes that use the Dawes name, but they are Asian imports with decals that spell out "Dawes". You will not see Reynolds 531 stickers on them.
