I bought an old road bike, and after fixing it a little went on my first ride and ended up with two flat tyres. Replacing the front tyre was fine, added new rim tape repaired the tube and was good to go. The rear tyre however, has 3 spokes which are poking through the rim and I have no idea how to fix them. Is there anyway I can repair it at home or will I need to visit a shop?

    That is a crazy amount of thread showing, something is really wrong. – Rider_X Jun 21 '18 at 19:51

Well, the easiest would be to trim off the excess of the spoke, preferably with the spoke not in the rim during this process. Or, more preferably, replace the spoke with the one of correct length.
However if you tend to keep the current spoke it may occur that due to incorrect length it does not have enough thread for the nipple to provide proper tension adjustment.

What is more important here is why is this spoke protruding the nipple? Is it of incorrect length? Is the rim not true? Is the lacing wrong?

Could you, perhaps, post a picture showing how this wheel is laced?

  • The easy way to trim the spoke is to use some sort of grinder on the exposed bit. Grind it down until the grinder just brushes the nipple. This is a technique sometimes used in the wheel factory. – Daniel R Hicks Jun 21 '18 at 21:40
