On carbon bars – what is the best way to make sure that the grips stick and don't move when wet? Or is that a "moon on a stick" question?

hairspray beleive it or not. 😛

SPRAY THE BARS WITH CHEAPO HAIRSPRAY – THE GRIPS WILL SLIDE ON EASILY AND THE HAIRSPARAY WILL DRY TO FORM AN ADHESIVE, KEEING THEM IN PLACE.

puncture glue

3m artists adhesive on bars and spray a little Iso Propyl Alcohol inside grips, slide on and leave to dry. They won't budge even in a thermonuclear explosion.

What happens if the hairspray gets wet – surely the grips will slip?

Hairspray only works if you don't ride in the rain, that's why I have resorted to a removable glue, but I can't remember the name.

no nails

Is hairspray ok on carbon bars?

3M spray glue

renthal grip glue??

+1 for artists spraymount.
It's also really good for sticking innertube to the chainstay.

I use araldite – sticks fairly permanently but can be peeled off when you want to get it off (foam grips would get trashed though).

Remeber its on carbon – are tehse methods safe?

disc brake cleaner – be quick – leave overnight

Hairspray, never had it slip, rain or shine.
