Will have a proper look in the daylight and get it all polished up properly, just in case spending some time on it shows up any other issues....although a quick going over with a torch around all the usual weak point seems to point to it being OK elsewhere....
Having all the patience of a small child....I've been out in the workshop with wet and dry!! This makes it look like there may still be a hairline crack to the right, but there definitely isn't, and nothing inside the tube.
What's the verdict, don't worry about it and ride it as is? I weigh 10st. if that helps, and am only 5'6", so there's not much leverage going on!!!
That don't look to serious Kaz but if you could get hold of a seat clamp with a deep banding then that would help strengthen the damaged area of the seat tube ..
Hmm, just been looking at it again and still not convinced there isn't a crack there past the hole. Trouble with a deep clamp is, it will foul on the welds.
Have messaged Danson, see what he says, can't think it's worth spending a lot on now....
Cheers chaps, I'll probably give that a go then. Any recommendations for the sort of clamp you mean, it's a 31.8, can't see a lot on line but then I don't really know what I'm looking for!!
