Sacramento, CA fixed/ss friendly shop: The bicycle business

Mostly a high end road shop but they all own and ride fixies to work every day. They have an online shop with a lot of track stuff competitively priced too www.thebikebiz.com

They don't always have everything in stock but they are happy to get it for you, even if it's not on their website or anything they've ever really stocked before. The staff is super friendly and knowledgeable about ss/fg. Their mechanic is crazy good (he was like 8th in cyclocross worlds in his day) and knows everything--serious.
