Need some suggestions on sprokets and freewheels. Whats good? Im looking to put Deity components. How many teeth should i be running in the back. Its going to be a single speed. Should i put a rear tensioner? The frame is a giant stp. The fork im undecided in. The reason i chose the frame is because i mainly dj and i want to start riding street and park. I know its not the best frame but its for a great price and it seems decent. Any help would be awesome. My hardtail now just doesnt cut it for street and park.
