No question, game changer
No question. Five stars. I use mechanical shifting and brakes. Running the cables was super easy and with downtube cable stops the cable run was straighter than anything except pre ergo. I ride a lot on the tops and keeping my elbows tucked is a game changer, Less neck and shoulder stress as well. Outstanding

Each of my 3 bikes now have RR bars
This is the 3rd set of RR bars - each of my 3 bikes (2 road and one urban/gravel) have been converted. I love this design. I like to move around on the bars and this adds at least 2 more ways to do this. The ergo is great. I thought the weight was a little higher but with the integrated garmin (or other mount) a light and/or bike computer offsets any added mounts and their extra weight. If I had a 4the bike I’d be buying a 4th set of RR’s.
