I have 16" apes. I can't get them to stop slipping and I've tried more than a few things.
I'm now considering an industrial grade 2 part epoxy glue between the chrome clamp and the steel bar. Anyone else try gluing?
Any other suggestions??

Regards

 

Don't get crazy.
Do you have a single top clamp, or a pair of top clamps?
You could just add a thin shim between the bars and the clamps... even a strip cut from a beer can is enough to increase the clamping force.

Cheap, aftermarket top clamps are also prone to being sized poorly.
The splines/teeth on the bars themselves could also be worn down now due to being twisted while clamped.

Another option is to replace the top clamp with one that has additional set screws to drive down into the top of the bar cross-over AFTER the clamp has been properly tightened.

 

Try E6000 or Amazing Goop Glue. Can be removed as one solid piece, not like epoxy that can break off or ground away with a tool. Have to let it cure for a day or two.

Next would be to grind down one side of the4 U clamp over the bars. The one side of the U would touch the front mount, then crush the open side so there is an air gap at the rear of the U clamps.

 

Something like this might help.

Cut a strip of old tire inner tube an put it between the bars and the clamp. If you don't have an old inner tube you could use some plastic wrap wrapped around the bars.

 

Simple fix. grind down the area of the top two or the bottom two holes of the top clamp. This will make the clamp actually tighter.
rigidthumper also had a great idea. I've never seen that type of clamp before today.

 

I've had success using a punch and a hammer. You dent the bars in a couple spots under the clamp. It distorts the bar enough to make the clamp grip. Old school stuff.

 

Yep, we call it "peening" was just going to mention this

 

Some good "tricks" in our co-member replies.

FWIW I would not use epoxy or glues.
I would use a thin shim or rubber tire stripe.
Peening may be the best option and the actual fix, yet I would try the shim first.
Good luck.

 

mark the position in the clamp and then bring to a machine shop and have the area knurled.
