clamp-on grips on carbon bars

Postby pharus » May 17th, 2013, 2:05 pm

My clamp-on grips only have a tightening screw on the inside end, not out on the handlebar end. I am leary of tightening too hard becuase the handlebar is carbon, yet the grip still tends to rotate while riding. I am planning to pick up some carbon friction paste at REI, would this solve the issue? Does this paste just go at the area where the tightening screw is, or under the entire grip?

Not carbon bars, but I used to use motorcycle grip adhesive by just squirting a couple dabs inside and then smearing it around with a popsicle stick and slide them on. They never moved again. Had to cut them off when they wore out, in fact.

Some clamp-on style grips suggest they are carbon bar compatible suggesting they have some way of dispersing the clamping forces. The BMX mechanic at my LBS says a lot of guys use hairspray for BMX style grips, seems like it should work with clamp-ons. Really shouldn't need much sticking power if the stickiness is spread over the entire surface area of the contact points.

The clamping force required to hold the grips in place is not all that great- most of mine require about the same as the brakes and shifters (4-5N). I've stripped out several clamping rings on Ergon grips well before they would crush a carbon bar. I don't know if it's still available, but years ago I used Jersey-mall-hair quality hairspray on the bars to hold grips in place. It adds just enough tack to hold them from twisting.

I have a tube of Park carbon paste (whatever it's called), and will gladly hook you up, as I will never use it all. :P

It does work, BTW.

Yes, the carbon paste will help. Use it under the whole grip. Also, feel free to go a little tighter with your clamping. If the clamp was on the outside edge of the bars, then I would say to look for some expansion plugs to reinforce the end of the bar. There use to be several makers of this plug, but I haven't been able to find any for customers in a while. May have to fire up my bench lathe and start making some.

If you go the hairspray route, get the cheapest aerosol "extra hold" spray you can get....Aquanet is my $1.99 spray of choice. It'll be plenty sticky for you.

I have used a misting of spray paint, always works, even with slip-on grips.
luckily I always keep a spray can of orange in my Camelbak for marking rocks and roots.:evil:
