Hi, Ive been searching the forum, ebay and google for the past hour trying to a 130mm chainring. Im having the hardest time finding something for 40 or under and I dont want a rocket chainring simply because I hear they arent that great. So any reccomendations would be great.

Also whats a good gear ratio? I like in Oakland/San Francisco, so its a mix of straight roads and hills. Thanks guys.
