Santa Barbara, Ventura, and Thousand Oaks have great bike shops if you're willing to drive. My ex lives near TO and is a roadie, showed me some good shops.

Its a good area for bike shops, a lot of ppl cycle in that area.

Good luck! Let me know if you need any help, I baught my mtn bike at a shop in TO. I also spent a lot of time in the area.

Cheers!
