put some taller bars on this weekend and they are really comfortable but they dont have any knurling where the risers clamp down on them, as such they move back and forth alittle, what can I do to remedy that?? thanks-

 

[Dan]

oops, hit the wrong button...

 

[caffeine]

take a punch and punch little "knurls" around maybe

 

[Mute]

What caffeine said. May also put little punch marks on the risers (where the bars ride)

 

[Dan]

good idea, I'll give it a shot....

If these are 7/8" bars you could bore out your risers to 1" and then use riser inserts. I'm pretty sure they are knurled both sides of the insert.

Tom was telling me about a trick using the alum from a beer can. Cut a strip, wrap around bars where they clamp and lock it down. Might be worth a try. I've got plenty of cans if ya need some...

I used that trick on my bmx when I was a kid. Worked fine for a while, but the aluminum wore out and the bars got loose.
But the bars on a bmx get jerked and pulled on alot more than a scoot so this might work for ya.

i've never done it but i've always heard you could drill a small hole in the bars and one in the risers and use a small pin/dowel to keep them where you want them.

set screw or 2?

I do that to some of the risers I make if the customer tells me his bars have no knurling in em. I drill and tap for a 10-32 set screw and sharpen the end of the SS to almost a point the put it in the hole leaving a little of the point sticking out. Bars are usually fairly soft (compared to the set screw) so it gets a pretty good bite on em..

 

[Dan]

how do you sharpen the set screw? by hand with a file??

 

[Danny F.]

Take a punch and hammer a lot of "dotted punches "around the risers area in the bar (or the risers), that's the only way it will work...inserting stuff will hold only for a while..

I have heard alot of these before..

I have also heard about using a small peice of emory cloth or sandpaper around the bar area that is gettin clamped

never tried it though.

try the beer can thing first..works good, and you get to drink the beer.

Nope, put an allen wrench in the end and then take it over to the grinder and grind an angle on it. Have lost a few of em, but at a few cents apiece, its not a biggy..

I used 1/4 20 set screws. Worked fine and you were able to take them out if you needed to remove the bars.

Seems this thread has perfect timing. My new bars are doing the same thing. I think Im gonna try the beer can strips first.

guys just stop by your local machine shop-alot of them have hand held knurlers and could whip that out for a case a beer...at least around here that works...best wishes..-cheif
the hand held tool looks like a pipe cutter but actually cuts small lines (knurls) in the surface.
