too-long spokes
Just built a wheel, and although it’s not fully tensioned yet, it’s a good guess that the drive-side spokes are too long by one mm.
I can feel the spokes under two layers of rim tape (Velox Fond de Jante). Two-inch tires will be mounted and run at about forty psi. Is it worth the effort to unlace the wheel and start over? Any advice appreciated, Bob |

Any advice appreciated, Bob IMO, if they're one mm too long, I would just grind them flat to the nipple, assuming you can get a tool to them. The deal is that you don't know how much too long they are until the wheel is fully tensioned. If I were building the wheel and the spokes were 1mm too long before the wheel was fully tensioned, I would be a little nervous and would probably swap in shorter spokes, depending on what I had sitting around, how much I wanted to spend and whether the wheel was that important to me. I've gotten away with too long spokes in beater wheels -- up to 2mm probably, but what happens to me is that the wheel gets beat up over time, spokes settle in, things happen, and you need to re-true the wheel, and you don't have any threads to work with. -- Jay Beattie. |

No. Whizz off one nipple at a time and put a washer or two under it. Use a power screwdriver where you can. if after tensioning, the spoke still protrudes so that it could show through the first tape, then file or grind it flush. Any advice appreciated, Bob |

Any advice appreciated, Bob I agree with the advice to carefully grind (or file) them shorter. One millimeter isn't much, and I've done that successfully. - Frank Krygowski |

too-long spokes
CHECK YOUR RIDE HISTORY....distances.....wheel rebuilds.....spokes out of whack..STRAIGHTEN WHEEL IN A WHEEL JIG ?
if you venture into these areas with some frequency consider buying new spokes at the correct lengths...ask the LBS for an eyeball add the GROUND DOWN spokes to the shelf. itsa tossup. if you ride distance not around the block or commute then probalillllities for a gross nagging screwup from those too long spokes is around the corner whereupon, bummmer you will do what ? buy correct length spokes !! BTW how did this happen ? drugs ? |

(In this case, I was rebuilding an ebay wheel, and had a box of new spokes onhand that were a little long. I felt like they were going above and beyond for me there.) |

I still think it IS a problem, so I’m going on to Plan B. I will post again, if Plan B works or if it does not work. (The calculation was a little non-standard, because I was using an Ultegra hub spaced to 135 -- with a replacement axle of correct length -- to fit my frame.) Bob |
