I am trying to assemble the rear wheel of my bike. I have sorted the spokes into two groups by their length. It seems like I do everything correct according to video tutorials and articles but when I put the last group of 8 spokes they appear to be longer than needed and the nipples come out of the rim by 0.5-1.0 cm. What is the reason ? Is it a common problem ?

  • Half the spokes on one side being too long is something I've never seen. However, you can't really tell that the spoke is too long until you've got the wheel trued and centered. Things can look very odd until you've got some tension in the wheel and the rim in roughly the correct location. – Fred the Magic Wonder Dog Aug 26 '14 at 20:52
  • Is it possible that I have done everything correct but the last set of 8 spokes seems to be too long – Abrahamyan Samvel Aug 26 '14 at 20:53
  • How many spokes on the wheel, total? Are you doing the same "cross" count as the wheel had originally? – Daniel R Hicks Aug 26 '14 at 21:13
  • Cross pattern does sound like a good thing to check, I got this wrong when lacing my first couple... – Stamfordone Aug 26 '14 at 21:38

    This (or the opposite) happens when you attach the spokes to the rim in an incorrect position, one hole further one way or the other. Also check the suggestion by @Stamfordone. – andy256 Aug 27 '14 at 2:41

Assuming that spokes are installed correctly, it might simply be that the axle is not centered. i.e. you under tightened the spokes on the side of the rim you built causing spokes to poke out the rim on the other side. it is important to evenly distribute mounted spokes around the rim when building a rim.
