I don't have those specific make but mine are up and back versions. Perfect and takes out the stretch in the arms which means that the shoulders are so much more relaxed. well worth it IMHO.
Put the Rox risers on my last gs as I was getting quite a pain between my shoulder blades.
I'm now having the same pains with my GSA LC but tbh I just don't want to fork out for another pair of Rox risers , so have gambled on some Chinese copies for £18.......worth a punt I thought
I put on the adjustable pivet Rox risers to allow me to get the bars as near to me as possible (Only 5'6").
The Pivot risers allow you to get the bars more back than up. Yes, they are expensive, but as they are now on their 2nd GS they have earned their keep.
They are probably the best mod I have made to the bike, much more comfort and most importantly, much more in control.
