Kjetil: have you installed both of the items above - I'm looking into having this installed on my bike AN UPDATE would be appreciated
Hey buddy
I bought these after reading some terror stories on "cheap" bar risers (not that french ones that I initially looked at were that cheap, per se)
I am 5'9 and I felt I was leaning too far forward on my gen 1 bike initially. But these bar risers made the bar come too close to me, honestly, and I think if I was to do it again I'd go for straight vertical (1") risers rather than an oblique, at least for my size. I ended up turning the handle bars quite a bit forward to compensate for the inch and a half forwarding that came with the bar riser, this also gave me a little bit more slack in the throttle wire which was quite borderline after installing the risers without changing the handle bar position away from me.
Technically, I installed hydraulic tube extensors for the brake and clutch. The throttle wires were barely long enough, and I had to bend the loop they pass through slightly.
Sorry if this is a somewhat messy response. I spent like 300 bucks on the whole thing and I don't really think I would have done it again had I known how little benefit it would yield -- for MY size and my arm lengths in specific.
Edit: One thing that it clearly did, as I am less leaning forward, is put less pressure on the wrist and carpal tunnel. I had some occasional numbness while maintaining throttle on longer distances if I didn't use a throttle lock. This is less of an issue now with the bar closer to me. I still think it would've been enough with just a vertical riser rather than the oblique one. But it'll depend on arm and torso length obviously.
