Custom bikes
This is the best shop! Not big and flashy, but its got everything that you could ever need. And if its not right there in the shop, he will get it for you in just a couple days. That's the best part about the shop, the owner knows everything and is the best go to biker guy.
His shop is in Encino, on Ventura east of Reseda. Check it out as soon as possible.
BTW, this LBS is way better than Cycle World! I live less than 5 minutes from cycle world but I take the extra 30 minutes each way to support the best bike shop in the SFV. Check it out! 818 344 2806
