Bike Lane did the fittings for my road and commuter bikes. They're a great shop, but they have a huge backlog of work right now (about 2 weeks for anything of consequence). They're opening a Reston shop with about 3 times as much workbench space, so if they get good mechanics there, it might be a good place.
Oasis Bike shop in Fairfax has a couple really good mechanics. I like the staff at REI in Fairfax as well as at Hudson Trail Outfitters. I've had off and on luck with both Performance shops in Fairfax and Reston.
Spokes in Vienna and Ashburn are both good.
