Seeking opinions about a chainstay dent. Serious?

Hello,

I have a frame and fork that I was thinking about putting on the market, but upon inspection I found a small dent in the non-drive side chainstay.
The bike is a Niner Sir 9, Reynolds 853 tubing. The dent is about 8mm long.

Is this serious? Possibly dangerous? There is a little paint damage that makes the dent look a little worse than it is.



Thanks in advance.

I wouldn't be too concerned about failure issues. Small size in the mid portion of a tube that's noot too thin a wall. I am curious as to the cause. The paint has an imprint on it that I don't identify. Maybe a tool drop? Or from a bike rack?


Now as to the effect on the sales price, that's another thing. What ever you do it's best to be up front and include this detail in any ad. Andy.

Andy,
Thanks for the reply. The cause of the dent was a clamp on kickstand that the previous owner had installed. What a shame, the rest of the frame is in beautiful condition. Oh well, not too much I can do about it now.

I certainly will note the dent when it comes time to sell the frame. At that point I guess I'll find out its effect on the value.

Thanks again.
Jeremy

Jeremy- Sorry to tangent this thread but i can't resist this. As a long time shop wrench i have tightened my fair share of kick stands (did two today). Yes, i've seen dented chainstays from the clamping forces as well as very scratched paint. So when i made my 3-spd which was to have a kick stand I tried to design a method to reduce the problems i see daily. So here's what i came up with. A set of pegs which trap the kick stand body from being able to rotate, therefore reducing the clamping forces needed. The pegs are simple nails brazed in place. They are spaced to be slightly closer together then the kickstand body is dimensioned. Then the body was filed as needed to fit and have the leg's angle along the stay be parallel. I never have seen this done before (perhaps my one addition to the building world) or after. Andy.

A lot of the better older bikes had a channel for the kickstand to settle into. Likely stopped for wieght. Pegs is a relatively elegant solution...
