I have an XCE with XR rockers and a romic. What are my options for a new shock without having to get new rockers? I really prefer coil vs. air, but I have not ridden an RP3 so I am open and have read most of the threads on the RP3 here. Any other suggestions? I am about 220. Not a lot still being dicussed on XCE (guess that's old school now), but I still love the bike and it has treated me well.
