I just received a pair of wheels that I ordered online. They are a replacement for a 1940'es vintage bike that now only takes "wulst"-type tires, which are only available in very poor quality at very high prices. The rims are of the Westwood type.

The front wheel looks perfect, with all spokes being a bit shorter than the nipples.

But on the rear wheel almost all the spokes protrude clearly into the (single wall) rim. Most of them just a bit, but maybe 10-15 of them seem more than 0.5 mm too long and I measured the worst 4-5 of them to protrude around 1.5 mm.

Surely rim tape will cover some protrusion, but how much? Will rim tape be enough to protect the tubes from this or should I go through the hassle of returning the wheel?

I'd really prefer to just slap them on the bike and not think too much about it, but on the other hand I bought these wheels to get better tires and fewer flats.

Here is an example from the rear wheel: This is one of the protruding spokes on the rear wheel

Here is what the front wheel looks like. All spokes on front wheel are like this

    The builder should have ground down the protruding spokes to be flush with the nipples. The one shown in the picture is projecting too far and will cause trouble down the road. Commented Aug 5, 2015 at 17:21

    Are you sure that the wheel is a true circle? If all the spokes are the same size none should protrude. This could indicate that the wheel is oval shaped. Make it spin and check if remains level with the brake-pads

That is poorly built and unacceptable (in my book) as a paid for product. If all of the spokes are protruding some, and several more than others, it means that the wrong length spokes were used.

The reasons for this may or may not be the wheelbuilders fault, it's possible that some component of the wheel build had incorrectly listed sizing and the spoke length calculation was off because of it (component manufacturer fault). However, it's also possible that the wheel builder didn't have the proper size spokes. The right way to do it in that case would be to take longer spokes and run them through a spoke cutter to get the proper length.

In the first case, rather than rebuild the wheel the extra spoke should have been filed down to the level of the nipple. This is acceptable as long as there is enough thread left to properly true the wheel. If too much is sticking out the wheel will need to be rebuilt or it will likely fail at a future truing when the nipple no long has enough threading to secure purchase on the spoke.

If the second case is true, and the builder doesn't have a spoke cutter and didn't want to order the proper size, I'm calling foul and would not send future business to them.

Unrelated to all that, it may be possible to get a rim strip thick enough to sufficiently protect your tube, but you really shouldn't have to go to that trouble.

    Thanks. I decided to shoot them an email expressing my dissatisfaction, but I'll probably end up filing them down myself before taping it over.

  • If you have a Dremel (or similar) tool with a mini grinding disk, it will be easier. Spokes are steel and hard to file.

    Having done this a few times, and seen it done by a professional mechanic many times, a file is the way to go. There is much less chance of damaging the nipple or rim. Dremel and similar tools have a tendency to jump, and a rim channel is a fairly confined space. Aluminum rims especially can be damaged fairly quickly. Commented Aug 7, 2015 at 8:41

    Best would be anyway to take the spoke out and replace it with the correct length!

    Definitely true on a single spoke. With multiples, however, you are likely to run into tension issues and eventually end up essentially rebuilding the wheel. If you don't have a dishing tool and other wheel building tools, that may be prohibitively difficult. Commented Aug 7, 2015 at 13:49

I build a rim and I went through the same trouble. I used some old spokes from a front rim to build a back wheel. The spokes came out past the nipples, I true the wheel and it's pretty straight. I left it like that and used some pieces of plastic to cover the holes than I used the strip together with 2 layers of electrical tape. It's holding on and the bike is running smooth. The rim I used it's double wall though so the spoke tips are in between the bottom and top wall they don't come out all the way through like in your case you need to cut them or use shorter ones they're going to destroy your inner tubes no matter what you cover them with.
