Riding a punctured rim!?

Anonymous

Hi guys, quick question. I bought a second hand bike recently with ksyrium sl wheels on it. I bought it knowing the rear rim had been punctured by a thin nail previously.
Basically the hole is about 3mm through both surfaces. The guy claims he has done 500m on it since it happened and I could believe that as the edges are dulled in keeping with a bit of oxidation.
So I was wondering what the consensus is...ride on it or new rim? I was considering jd weld to fill both sides.
I have done a search and advice is conflicting, although the holes discussed previously were more significant, this is a lot smaller than a spoke hole even.
Any advice appreciated

That should be ok with decent rim tape covering the hole. Its no more a hole than a valve hole so wont compromise rim integrity. JUst try and get something to fill it as water getting in will have an effect on the handling.

Rims have holes... One extra should not be a problem, as long as it is covered with tape internally. I would coat it externally with gaffer tape to avoid water entering and periodically replacing the tape looking for possible cracks. Otherwise fine

Cheers guys, appreciate it! I plan on filling +/- tape on the inner surface and either a tiny grommet or filling the outer surface for that reason

Pop some insulting tape on the outside, from the inside fill with a blob of Araldite: when dry peel off the insulting tape - it will mean that the outside will perfectly smooth and you won't notice the fill, the inside you smooth down as you apply.

Because insulting tape is plastic and not that sticky it means that it won't stick to the Araldite. Araldite won't affect any surfaces and will last, basically, forever.

This is good advice - I used this technique to repair a crash scuffed saddle remarkably successfully!

Yeah that should be fine, just keep an eye on it for any cracks starting from the hole (probably wouldn't though as it shouldn't be very stressed in that area, unlike spoke holes themselves where it sometimes happens).
