DIY handlebar shim

[IDB1]

Been hunting around for a 1" to 1 1/8" handlebar shim to no avail.

Found some 1 1/16" (1.2mm) stainless steel sheet on t'interweb, is it practical /safe to cut a couple of pieces of the right shape and size to make my own (shim)?

Or is there more to it??

Is it for steerer or bars? The reason I ask is steerers are nrmally measured 1"/1 1/8" etc and bars are 25.4/26.0/31.8mm

 

[IDB1]

It's for bars and they are 28.6

I have the same dilemma - are they Azonic bars by chance?

 

[IDB1]

yeah . .

can't see it being a major biggie tbh.. in theory there's no reason why this shim won' be ok (in the same way that coke can shims are fine too)..

Just want to be sure . . . .

And this will be cheaper than shop bought too.. by a long stretch

For a fiver you can get an alloy use shim that does 25.0 to 26.2 (1.2mm), pre curved and nicely finished. Just trim off one end and you could split it or leave as is:

You could even buy one between the two of you by cutting it in half!

Been looking at those very shims for the past few days (have a USE post to go into a '98 Avalanche frame) and there were no pennies dropping

It'd have top be split lengthways though, for riser bars.. a little care and some sanding would sort that though....

**didn't get any sleep last night edit** . . I'm not thinking right.. need to shim down from o/s to 28.6 :roll:

The bars require a 28.6 clamp so the stem would have to be o/s (31.8 ??) and shimmed down.. not bloody 25 - 28.6 :roll:

Christ! they're like buses these things ..have exactly the same dilemma here too!

Was going to do the same thing and use a seatpost shim cut in half etc like you said. Isn't it 1.6mm needed though for 28.6-31.8?

 

[IDB1]

Yeah. . 1.6 . . . Bit fuzzy in the head today, not much kip in the last 24hrs. .

27.2-30.4mm shim gives you the 3.2mm (1.6mm thickness) you're after!
