We’ve given our 24″ parts selection a specific name, so if you start seeing Plus 4 don’t be confused. The way these bikes ride, its just a 20″ plus 4″ more. There’s not too much of a difference in feel. The term “cruiser” doesn’t describe these parts very well. Either way the Plus 4 edition of our product line will essentially be our regular products, bumped up to modern 24″ geometry. Available now are the Plus 4 editions of the Morning fork entitled Morning 24.1 and the Forumph bar called the 24ump. Model C frames are currently on the water and should be available in the US sometime around mid-April.
