I'm "hanging it up". I've ridden the bike sparsely but with enormous enjoyment. It is super light but tough and durable. I retired from riding, after an injury last year, and have finally come to terms with selling. Going back to hiking. In the 2 years I rode it I had it "tuned up" twice. Included is slime, chain lube, CO & inflator, valves, pump, and various accessories. 2 bike helmets, 2 sets of riding gloves, along with saddle bag.
