I'm sorry, how much for grips! Do they make much of a difference beyond that of a good pair of gloves (which I could buy along with some good grips and still have change for a pint or three)
Ergonomically speaking Mark, they are quite different indeed to to standard grips and a pair of gloves. The ones I have now on the C'dale are £19.95 with end caps. Remembering from days gone by how uncomfortable I found straight bar grips after a long ride; I can truthfully say they are worth their weight and shape in gold …to me at any rate. Hence why I asked about a replacement like for like. In the days of carpel Tunnel syndrome and compressed fibres and nerves generally, it makes sense to me to go with a grip that actually does make a difference.
Having tried a quick ride round the block on a bike with bog standard straight grips, I can hand on heart say I'd not ever be without the shaped Ergon's from here on in. Prices vary depending on type, mine are just quite standard and cheap for what they are. Size was my problem as my hands are unusually large for my build.
