    question re: theoretical strength of a wheel

    ok, all other things being equal, what'd be stronger: a rear SS/FG wheel with a 130mm hub, or the same built up with a 135mm hub? i'm thinking of building a cross check with a flip/flop, and the things are spaced 132.5. which hub will be stronger in the long run?

    thanks,
    -rob

    the strength difference would only come into play if you knew the distance between flanges. It's going to be negligible, but a wider base of a triangle leads to a stronger shape.

    Assuming the flanges and bearings are the same on both, the shorter axle would be stronger.

    ah-ha. 2 different opinions here, then. let's make it easier. velocity aeroheads, wheelsmith 14/15 butted spokes (of appropriate length for each application), surly new hubs, fixed/free, in either 130 or 135mm versions. what's stronger?

    except axle failure is rare. How well the rim stays true is a better measure and the 135(assuming the flanges are set wider) will put up with more abuse and stay true.

    It looks like surly makes a 135 and a 120 version. If the 130 is a spaced out 120 it would be weaker if it is a spaced down 135 there would be no meaningful difference.

    (38.4 ctf on the 135 and 30.1 on the 120)

    i think surly stopped making the 130mm fix/free version, based on what i see on their website. actually, i think they stopped making all the 130mm versions, but they used to make them, and i can still get them thru the shop/qbp. i'm leaning towards the 135mm version either way right now, tho, as i think it might be more versatile for application in future projects, feel me?
