elkhide sew-on city grips from Velo Orange. From a user's viewpoint, these are probably my favourite things to put on upright handlebars, because they feel the most comfortable to grip: not too hard and not to soft, just right. However, from an installer's viewpoint, they are kind of a pain to sew on and it takes forever. I've put them on two of my bicycles so far (the Royal H. and the Gazelle), each time thinking "never again!" while doing it. And yet, they are so comfortable, that I've just ordered another set.
