Left of field, I still love Ritchey foam grips.
If you don’t like them ‘throttling’* a little dab of superglue under each end to hold them in place, wipes off with acetone (nail varnish removed).
Now trying some ergons on the Fatty, different, but so far so good. It doesn’t feel like it looks if that makes sense. It just feels like someone designed a grip to fit your hand, rather than trying to hold onto a cylinder which isn’t really what hands do best.
*TBH, I find they move rather than spin, and on some bars more than others, but superglue works and wipes off in seconds, have to destroy the grip though, but only a fraction of ODI prices.
