I just wanted to give these guys a nice plug in for riders in the San Francisco BayArea. A couple of weeks back they were giving out free Dyno's and I was fortunate to get mine done and convinced I really need to get on the ball and get a major tune up. Northern California Cycles in Milbrea, California and are great guys, very knowledgeable and will work with you price wise with labor and parts. Thumbs up for them.
