Spoke length help
I want to rebuild a wheel with a Shimano 105 six speed freewheel 126mm hub and
a Wolber Alpine rim. I will reuse the rim. The wheel is from a 1988 bike. Dan Halen's spoke calculator gives a lengths of 299 and 298mm for 3 cross 32 spoke lacing. I removed a left and right side spoke and measured lengths of 302 and 296. What length spokes do I need? Any idea why the difference between the calculated and actual lengths? |

The previous spokes were a little short on the right and long on the left. You had left spokes protruding from the back side of the nipples and right spokes that didn't have full thread engagement. -- daveornee |

It is possible that I picked a spoke that had been replaced by one of slightly wrong length. Anyway I am will get spokes that split the difference. |

many believe
few are chosen no that's not it uh most circular rims are not circular do not count on scientific precision when approaching the practice of wheel building buy a few longs and shorts to compliment your day |
