I'm the proud owner of a new Long Haul Trucker. I was told I should bring my bike back to the shop after a couple hundred miles for a tune up. Since getting the bike home, I've tightened the lose steering cap and stem, adjusted the rear derailleur that wouldn't shift into the lowest sprocket and now adjusted the brakes since I was running out of lever before full braking power was applied. The brakes are cantilever and they weren't applying evenly on both sides, either.
So I'm wondering, what else would the shop do for a check up at 200 miles? I might just do it myself. I have next to no experience with bikes but I'm generally handy with mechanical things.
