    Drive side rear spoke length on Downtube Mini?

    Found a broken drive side spoke today. Can anyone save me the faffing with Spocalc and my ancient atrophied brain, and just tell me what length I need? I'd love you forever, probably.

    I just happen to have a broken one on my desk here, and it is exactly 110 mm long. It is broken right at the beginning of the curve at the head; so the whole thing was probably 1 or 2 mm longer.

    Best bet, though, is to measure your spokes. If keeping the same size, have the LBS make several replacements; with your weight, you'll be going through them like popcorn.

    Almost a year ago, having broken about ten of them, I replaced all the drive side spokes with longer ones. I kept the old ones as spares for the non-drive side in case they, too, should start popping on me (just one, so far). On the drive side I put some spokes I already had, and they turned out to be four cross or something slightly crazy; I put all heads are on the inside, and each spoke curls around the hub a little ways before heading off at its tangent. It looks odd, but I haven't broken one of those yet!

    Best of luck....

    I can tell you when I get home ... although now that I think about it, I used a different rim. So I probably can't help you.

    Sammyboy: Breaking spokes usually point to insufficiently tensioned spokes.

    Yeah, I figured that whilst I've got the wheel in the stand I'd tension the whole thing.
