I was pretty sceptical and had heard all the ‘no good for technical riding’ type comments but I saw some for £3 at the Bristol bike jumble so thought I’d give them a punt given that I’ve often suffered with pain in the outside of my hands when mtbing almost irrespective of adjustments I’ve tried and just learnt to live with it.
In short, I rarely get the pain when using the ergons. I don’t find them any different for technical riding either so for me, it’s all win.
I still use normal grips on my other bikes but that’s because I don’t usually ride them for more than 2 hours so hand pain is less of an issue.
