I'd like to have my bars closer to me. In looking at some other posts here the general opinion is that a pullback riser can be installed without changing cables. Anyone had experience with this that can make a recommendation on which riser would give the most pullback? I've already rolled the bars back a bit but it's not enough. Not really interested in height, but if it comes with it thats ok. I just don't want to have to change the cables. Is it a easy do it yourself install? Thanks for any help in advance.
