Mike's Bikes of Pleasanton at 6754 Bernal Avenue #710, Pleasanton, California.

Took my old mountain bike in that had not been professionally tuned in 5 years for the $99 tune up. Service person said they would call when it was ready-they didn't. I called a week later and was told it was done. As I rode it home I noticed that the derailleurs, the issue I had taken it in for, were still not working. Additionally, the front wheel was still as off true as it had been when I took it in. I took it back in and they fixed the derailleur issue (hence the two stars), however I really don't believe that they did much actual work on the bike since it didn't ride any differently from when I took it in

I would not recommend going here for service.
