Anyone got the lowdown on late 80's MBK's. This 'Adventure' has the full Exage country component set including thumbies, bio pace chainset, and chainstay mounted brake. Paint is a near fluro orange to yellow fade. Still rides really sweet and is my trailer tower for the school/nursery run so ive managed to strip the threads from the QR scewer (now replaced with a solid spindle) really original bike in good nick bar the battered rear mech which is annoyingly weak in the spings and bent out a few degrees. Anyone got a mech to go with the info??
