Dented seat tube

So someone tried to steal my Charge at the weekend. While levering the lock, they put quite a large dent in the seat tube.

I'm not sure how safe it would be to just keep riding the frame like this, any ideas ?
I was debating trying to get it fixed, or just buy a new frame as I do fancy something different. This is a 2008 charge, which has had a very full life ;)

It's fine.

Ok well guess the charge really is my beater now ;)

I was just worried that the dent could lead to the tubing folding in on itself while riding, that would be interesting and painful!

Being a seat tube though it isn't going to fail catastrophically. I "know" a bike that is still ridden with the seat tube broken at the bottom bracket, it makes a clattering sound over bumps, but it has done so for ages!
It has reduced the resale value of your bike, but it doesn't look like it was much anyway!

Could you remove seat pin put a long bar of metal with a long smooth taper on the end down the seat tube and gently ease the dent out by tapping with a hammer the end of the bar.
also some grease will help lubricate the two surfaces as you knock the taper down.
Bear in mind that the tube with the dent in will have stretched and you will not be able to easily get it back to how it was.

thanks for the tips... handy to know. I don't think I'll bother trying to ease the dent out, makes it less likely people will try steal it ;)

Get the frame powder coated, it'll fill in some of the dent and it'll not look as bad.

Look the frame over a bit to make sure nothing else was damaged . Around seat lug or bb shell.

Some thieves man handle a bike to get the lock off and end up cracking something else.

If not the you can fill it in ,sand down and repaint.

S/F,
CEYA!

I've been riding my Condor for the past 18 months without a problem and it most likely has thinner gauge steel tubing than the Plug.

it's fine. Another 5 years at least left in it.
