I had an '82 610 with caliper brakes, suntour components and a 5 speed freewheel despite 126mm spacing and not a lot else to differentiate it as a touring bike. The '85 was a much more purpose built bike with front rack mounts and cantilevers but both '82 and '85 still used 27" tires. This 88 builds on that (no fork mounts) but has 700c rear and indexed shifting but still maintains the shimano light action of the '85.
A blast from the past
