can you bend a front derailleur clamp?

Has anyone ever tried to bend a front derailler clamp to accomodate a bigger seat tube size? I'm trying to go from a 31.8mm to a 34.9mm tube. This is an FD-4500B Tiagra type.

It won't work, but that's not too expensive a component.

Buy the correct size and sell the old one on ebay.

You can bend it. But it probably won't work. And given how cheap FDs are, it's not really worth it.

Its one of the cheapest components on the bike. Saving you the stress is worth the $40.

That's what I thought. Even if you could bend the thing (those clamps are hefty looking), the bolt probably wouldn't line up anymore.

Thanks, I'll pony up and stop being so cheap. Cheers

One time to protect a respray I put handlebar cloth tape under a campag record front clanger and when I tightened it the clamp snapped! That's how precise the size is.

I'd say that is more an indicator of how unforgiving the clamp material is.
