It would depend a bit on how comfortable you are with doing your own maintenance, or how expensive shop time is.

At $220, I would expect the bike to be mostly rideable (with perhaps some minor tuning issues, but nothing major).

• DOES IT FIT?
• Check the joints and welds in the bike frame for cracks. Sometimes it is difficult to tell the difference between a paint scratch and a crack, but look for natural stress points as an indication. A major crack would be a show stopper.
• The Brifters are one of the more expensive components, and a pain to replace (Microshift 7x2 and 7x3 is available). But, I'd make sure you can shift up and down through all the gears (hopefully everything is adjusted).
• Wheels can be trued if not too bad, but look for big dents in the rim (or surging when braking), and that the wheels run reasonably true. Also make sure there are no cracks in the rim around the nipples. Also deeply concave brake tracks may indicate a rim replacement in the near future.
• See if the wheel wiggles side to side when moving it with the hand, and ask the seller whether the hubs and bottom bracket have been serviced (not a big deal, but good to
• Tire Condition. I usually don't consider this very much, but new tires will cost $40 to $100 for the pair.
• Take it out for a short test ride.
