I’ve used various foam grips over the years, here’s my two penny’s worth:
1) Forget lock-on grips, you lose lots of comfort compared to a pure foam grip as you replace a good amount of nice soft, light foam with hard plastic shell. Also, the hard collars are a nasty rim on the edge of the grip compared to the soft crntre and hurt the outside of your hands on a long ride
2) Old school foam grips are comfy and super light but, after a few months use, get permanently compressed so can need replacing. Also, some can get slippery when wet. Replacement is quick and easy and they’re nice and cheap – bonus!
3) ESI grips seem very good, I’ve used them through the winter and for 24hrs, nice and comfy, seem to hold their spring for substantially longer than old school foam, they also stick to the bars without any drama, stay grippy in the wet, despite smooth round surface, are still light and, importantly, come in pretty colours 😉 but they are more expensive and harder to get hold of then plain black foam grips from other people
Hope that’s useful
