Claud Butler 1987 Catalog. Brake mount types are cantilever or V brake for front, U brake ONLY for rear. This is a Low mileage 87 or 88 model, pretty sure its 1987 as catalogue looks right but i cant find 88 catalogue to check, nearly all parts of bike where dated 1987 but there is a few original parts dated 1988, maybe they didn't update model for 88.i don't know.
