Another exciting day. In response to an ad I placed, I got offered a Bianchi of a type I was unfamiliar with for what I consider to be a fair price considering that the large front sprocket is worn. It is a 1988 (?) steel framed "Super Grizzly" with a complete Shimano Deore XT group and Shimano BioPace 48 X 38 X 28 teeth sprockets. I know these bikes used to be expensive highly prized but are these old ones still very desirable ?? Other than needing a large sprocket, it seems to be in fairly good shape. Good deal for $100.00 ?
