We did a full upgrade on this bike. The original rigid fork was toast, so we upgraded to a Answer Manitou Three (1" Threaded) Suspension Fork. The old tired grip shifters were upgraded to Suntour M8 Trigger Shifters. The worn out Shimano cantilever brakes were upgraded to Origin8 Pro Cantilever Brakes. The dry rotted tires were replaced with Kenda K-Rad 26x2.3 Tires.
In addition, it has new grips, tubes, and chain!
Frame Size 19.5", Asking $200
