Installing Drop Levers on Small Diameter Handlebar
I am in the process of swapping the porteur handlebar on my Peugeot to a dropbar that I have laying around the basement and which I received from rhm a few months back. Because the diameter of the bar (22.2mm) is too small for the clamp on the lever (23.8mm), it will not tighten sufficiently. Here are my questions:
Thanks folks!
- Can I safely shim the levers?
- Can a piece of inner tube be used as a shim, assuming it is safe to do so?
- If inner tube is not suggested for shim material, what else could be used for a shim?
Thanks folks!

A lot of those clamps came in sizes, might want to dig through a box at the co-op or your LBS. Not sure a soft matl shim is going to be stable enough

I agree. Best to have the right clamp, or, failing that, I would shim it with appropriately sized alum. shim stock (usually available at the lhs) rather than something pliable.
[edit] Nothing wrong with the soda can material, but it's going to be too thin I think. I'd rather just have one piece the right thickness rather than several wraps of something thin.

The strips glued together with epoxy idea sounds workable to me.

What kind of levers? For some reason I have a lot more 22.2 mm clamps than 23.8 mm clamps. And a lot more 23.8 mm drop bars than 22.2 mm drop bars.

just got to the coop and the the right ones- the bigger ones are more valuable to you when you need them.
I got plenty of 22mm ones and wish i hade more bigger ones.

There's no need to shim the clamps. Send me an email if you need a pair of 22.2mm clamps to fit Dia Compe/Weinmann levers.

Installing Drop Levers on Small Diameter Handlebar
Thanks for the input guys. I think I have a set of 22.2 clamps on the way. WRT the co-op having them available, the closest one is 50 miles away. The LBS is a very small operation and I'm supporting him to the extent possible, but he has very little stuff in stock. He knows I'm a different animal with my bikes and won't get much direct business from me since my bikes are so old, but he knows I'll get consumables from him and will send people his way.
