Anyone know of a good way to keep bars from slipping? I purchased some flanders bars that are not knurled. I put some shims I cut from pop cans and tightened them way tight but they still would move! Any suggestions?
Thanks

My Flanders wide clubman are not knurled and fit fine. No slipping at all. Are you sure you got the 1" bars? Also make sure you tighten them down evenly a little bit at a time and not tighten down all one side and then the other. If they still slip you might try scoring the area to be clamped along with the soda shims first. Good luck.

I did try to tighten evenly but I have not tried scuffing them up first. I might try that. thanks

Rain, I had this problem with some Mecatwin bars, which were smaller in diameter than 1" and not knurled. Mecatwin told me to take the top part of the handlebar bracket and rub the flat surface on some abrasive paper. Apparently, it only requires a few minutes to reduce the bracket enough to allow more of a gap that then allows the bolts to clamp down before meeting the bracket base. Not wanting to do this at the time, I bought new bars instead, but it may be worth considering if the other suggestions don't work.

By the way, the NH bars I have on at present are not knurled either but they do not slip. Personally, I'd be more inclined to rub down the bracket underside and/ or use coke can aluminium shim rather than scoring the chrome on the bars. You won't harm the bracket's ability to grip properly should you wish to change bars in the future.

Good luck.

It might help to put some hard rubber inserts made out of old inner tube or something like that. It worked for me.

As I recall the torque spec calls for the top bolts to be tightened first, then the bottom bolts.

I have m-bars and have not had any issues.

I agree with LS1. I dont remember where I read it, but thats what I did.

I'll try some of those ideas tomorrow. The bars were advertized as 1". I have been tightening the bolts evenly. I think I will start with the back first idea. Thengo from there. Thanks agian.

I did the method of tightening the top bolts first then the bottom. So far so good. Thanks

I agree with the soda/beer can shim method.
