LOL. Interesting fart related antics. The grip looks good to me because it feels good to my hand. The ringlets are not all perfectly even, as they could have been, because the slight regularities make it grippy and add a touch more give.
DannyBazz - noting particularly wrong with rubber, but the ones I had stained my hands black every ride - that was just the ones I had, does no one else get that?
They were also loads more sweaty-slippy - again that could just be my weird paws.
