How much of a problem is this?

Attaching a Thule child seat to my commuter/beater this afternoon and I appear to have crushed the seat tube.

Followed the guidance of 8nm, and from the weight of the frame had assumed it was made from some not very fancy steel. However it has definitely been crimped by the clamp.

To those that know more than me about steel frames: any thoughts on how much of a problem this is would be really helpful. Obviously want this to be safe if i am going transport our son on it.

Many thanks in advance.

General riding, fine.

Reclamping with kiddo seat, not worth the risk.

Thanks that is helpful. Is it the reclamping that is going to be a particular issue, or is this a more general precaution?

Also - I don’t know if you know if i have been unlucky here, or whether 8nm was always going to be a bit much. The frame is a low grade Columbus tube set I believe.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
