My bike shop is The Bike Lane. Their original location is in Burke, Va, and they just opened a second shop in Reston Town Center right off the WOD trail. The owners, Anne and Todd Mader, are both active cyclists and are also very supportive of the local cycling community. They have a good selection of women-specific bikes and accessories and also do a great job with bike fitting.

They lead a weekly Saturday morning road ride at their Burke location and they're also starting up weekly rides at their Reston shop (they only just opened at the end of June). They also have a race team.
