ie Bikes - My personal favorite shop in Murrieta (now on Washington Ave.) They don't have any current organized rides but Matt (the owner) is a good guy to know if you need work on your ride.

Temecula Velo - Another local club with Beginner to Intermediate level rides. They also organize and multi club ride once a month that gets good attendance.
