20" approx - aluminium frame...........I've no idea what it is, but it's of reasonable quality, looks a bit tatty but would build into a nice riding hack bike for commuting and getting around town.The mech hanger was a bit bent at some stage, but will tweak back into shape. Late nineties, all standard stuff, most of a Tioga headset included. Would cost more to post than I want for it, so collect only thanks. Token price of £5!
