...but they work really well, on un-gloved hands at least. Easy to fit, once I'd got the old ones off; they just slid on and were easily locked in place though I had to move both the levers and shifters 1.5 cms in.
I was struggling with the supplied grips on my Jamis Durango Sport, they were made of a very firm material, my wrists were aching and bizarrely my neck and shoulders too. These ergonomic grips have made a huge difference; they fit my hand beautifully, the wider surface and softer material spread the load over the palm and they've taken away all my aches!
The only reservation I have is that they are not quite so effective and secure when I'm wearing my windstopper gloves, maybe I need some closer fitting ones, and...I'm not sure I like the look of them on the bike; they look a bit over the top!!
