    Default 130mm axle in a 135mm hub?

    Common issue. I've been commuting on a 1990 Trek 950 for a few years and the original rear wheel is near the end of it's long life. I'll most likely buy a prebuilt set of 26" wheels to replace the originals, and they will have 135mm rear dropout spacing, whereas the frame has 130mm spacing. I would rather not cold-set the frame for 135mm, or build a custom wheel for an aging bike if I don't have to. Can I just reuse the axle from the old 130mm hub in the 135mm hub?

    It's a steel frame. Just put the wider wheel in. There's probably enough flex in the stays that you don't need to cold press it.

    I have a Trek 620 with 126 mm spacing and just shoved a 8-speed 130 mm rear wheel in with no problems.

    Changing hubs is not a small feat.
    Of course you could try trolling ebay for a 26" wheel built on 130 mm hubs.

    Ditto on just using the 135 hub in the 130-spaced frame. It will work just fine. little to no effort.

    However, I have done exactly what you propose. That is, to run a 130 OLD hub in a 135 OLD hub shell. it's not tough, just a bit fiddly to get the cones set, i.e., to get the hub/rim centered in the frame. You'll need either a wheel dishing tool or at the very least a decent truing stand. Most (older) 135 hubs can fit, but you'll be removing a few washers between the cones and the outer locknuts. Trying to get the hub/rim centered in the frame using the frame will be frustrating.

    I would also use the 135 hub. If you are still using a 7 speed cassette, you will need a 4.5 mm spacer behind the cassette on the new hub.

    Another vote for "just use a 135mm hub". I had a steel Poprad disc frame for several years that was originally 130mm; since disc 130mm hubs are hard to find I just used 135mm MTB hubs and it worked perfectly fine. I think that Surly even sets their disc frames at 132.5 so either spacing works. It isn't hard to move steel stays 5mm.
