Brake levers on a mustache bar

When you ride in the hoods on a mustache bar, you apply force on your brake levers. I can (if I try) rotate them, no matter how hard I torque the brake levers onto the bar.

I would not worry about this on a traditional drop bar, because you never push on the sides of the brake levers. But with the mustache setup, you are basically pushing on the sides of the levers.

Should it be possible to tighten these levers so they don't move even if I put a lot of weight on them? I certainly can't do it with my current set of hex wrenches. If I got big hex wrenches like Park's PH-1 set, would this allow me to tighten the levers enough? Here's a link to the wrenches: http://aebike.com/page.cfm?action=de...=30&SKU=TL7487

Somebody also mentioned using a shim, like an inner tube if the size of the brake levers doesn't match the handlebars, but they should absolutely be compatible diameters.

I think this is a case of "well then don't do that".

Do you have any reason for putting so much weight on nothing but the hoods other than trying to see if they'll move? For me with mustache bars standing up I don't want to be gripping the hoods and sitting down if I do have my hands on the hoods I don't have much weight on them... so if you're already really screwing them down if they don't move during normal riding there's nothing to worry about. Unless I'm misunderstanding and you're saying they do move during normal riding. If that's the case it could be where you have the levers placed along the bar. A slightly different spot might give the clamps and the back of the hoods a better grip.

when I had a moustache bar on my commuting bike, I never actually put any weight on the side of the hoods. If my hands were on the hoods, the heel of my hand was still on the bar itself, and that's where the weight went.

I'm building up a singlespeed with a steel moustache bar and on a bar like that I can just crank down on the brake hood-fasteners without worrying about the bar collapsing, but probably won't worry about doing so anyway.
