We had a tandem a while ago and now we want to get one again. We found a 1995 Santana Arriva Tandem Bicycle, Size: 58 cm front and 53 cm rear with Shimano Deore components with 28/44/54 front chain rings and 8 speed 12 - 32 rear cassette and Shimano Bar End shifters. They are asking $650. Is this a good buy? I am 6 ft and my wife is 5' 6". Will we fit ok on this size?
