Dunno. I was going with the RM1 but now see the RM2 is out there for a bit less and with a potentially better feature plus it mounts under the bars. OK... then you look at what Scott is offering now that one sounds good too. I am looking for ease of install and ease of adjusting as I am tool-time geek and need simple attachment. I have basic skills that so far seem to be working ok. Pros of one over the other? Pipe in if you can edumucate me on steering dampers if you can. Gotta do this in the spring. Thanks!
