    I would go with new ones if money wasn't too tight. Spokes very often (most often?) break because of metal fatigue, and putting in fresh ones now while you're unlacing and re-lacing the wheel gets you a fresh start. You can save a few shekels by reusing them but it's much easier to replace them now than it will be later.

    It's also a chance to upgrade to a better spoke if you think there's something to be gained there. (E.g., double-butted spokes are not only lighter but the extra spring from thinner middle part is said to reduce reversing loads at the vulnerable ends where they tend to break over time.)

      I had to order new ones because I was mistaken about spoke lengths, but thanks for the adwise anyway.

        I've finally built my first 36'er wheel, but not without problems. I though it would be a good idea to use threadlock instead of lenseed oil. It was not. Once I had the wheel laced, I could not tighten the nippels because they got stuck. I managed to salvage the spokes, but had to order new nipples. Went back to lenseed oil.

        The threads on the spokes were not equally long, which made the initial thightening a bit more difficult.

        When I started I couldn't quite remember how to lace the wheel, so I made some notes that I'll post her so I'll find it later. I do it like Sheldon Brown and not like the video I linked to in my initial post. The difference is that I get the trailing spokes running on the inside of the flange, which is supposed to be better/stronger.


        36 spokes: 4 groupes of spokes (4 x 9)
        ========================

        The first group

        Look at the hub from the RIGHT side.

        DISHED WHEEL: If this is a dished wheel with an inboard disc rotor on the left side, the LONGEST spokes goes on this side. Put the shortest spokes away so you don't mix them.

        The first group of spokes goes into the hub from the OUTSIDE of the flange on the RIGHT side of the hub.

        Put spokes in every other hole.

        THE FIRST SPOKE: Put the first spoke (key spoke) into the rim in the first hole to the RIGHT of the valve stem hole.

        OFFSET HOLES: If the holes in the rim are offset, you should choose the first or the second hole to the right of the valve stem hole depending on which one is on the right side of the rim.

        Put the rest of the spokes in every fourth hole in the rim.

        The second group

        Look at the wheel from the LEFT side. Turn the wheel so that the valve hole is at the top of the wheel.

        DISHED WHEEL: If this is a dished wheel with an inboard disc rotor on the left side, the SHORTEST spokes goes on this side. Put the longest spokes away so you don't mix them.

        The second group of spokes goes into the hub from the OUTSIDE of the flange on the LEFT side of the hub.

        Install one spoke at a time.

        THE FIRST SPOKE: The first spoke of the second group (the 10th spoke) should go into the rim just to the LEFT of the key spoke (looking at the wheel from the left side).

        OFFSET HOLES: If the holes in the rim are offset, you should put the second spoke in so that there are spokes in the two holes to the left of the valve stem hole.

        (When the 10th spoke is installed, the rim should have to spokes next to each other next to the valve stem hole. The key spoke and the 10th spoke must not cross each other)

        NEXT 8 SPOKES: Install the other 8 spokes in this group following the same pattern.

        The third groupThe fourth group

        Look at the wheel from the LEFT side.

        The spokes gos into the wheel following the same pattern as the third group.

          Just finished my 5th. wheel. KH Freeride 27.5 rim with a KH Spirit hub.

          According to the spokes calculator, 26.99mm is the correct spoke length. The closest to that I could get from UDC UK was 265mm, so I went with that. From experience, the spokes that are cut and threaded from the factory works better than if you use UDC's cutting and threading service. The spokes came with 16mm nipples and they went about 11mm into the nipples. I asked UDC UK about it, and they said it should be ok.

          As for spoke tension, I read somewhere 100-110 kgf would be good, so I went with 24/25 on the Park Tool tension meter (107/120 kgf).

          The Freeride rim has offset spoke holes, but my lacing description covers that, so no problem.

          After lacing and initial tightening, I got the dishing and truing right. After that, I made sure all the spokes were about 15 on the Park Tool. I then brought the tension up to over 20 and started with the detensioning (I placed the wheel on the ground and stood on it). After that I adjusted the dishing and trued the wheel before bringing the tension up to 24/25 on the Park tool.

            The text got warped somehow, so Ill split it. New wheelbuild underway.

            PART I

            36 spokes: 4 groupes of spokes (4 x 9)
            (32 spokes rim and hub is EXACTLY the same except it's 8 spokes in each group)
            ========================

            The first group

            Look at the hub from the RIGHT side.

            DISHED WHEEL: If this is a dished wheel with an inboard disc rotor on the left side, the LONGEST spokes goes on this side. Put the shortest spokes away so you don't mix them.

            The first group of spokes goes into the hub from the OUTSIDE of the flange on the RIGHT side of the hub.

            Put spokes in every other hole.

            THE FIRST SPOKE: Put the first spoke (key spoke) into the rim in the first hole to the RIGHT of the valve stem hole.

            OFFSET HOLES: If the holes in the rim are offset, you should choose the first or the second hole to the right of the valve stem hole depending on which one is on the right side of the rim.

            Put the rest of the spokes in every fourth hole in the rim.

            The second group

            Look at the wheel from the LEFT side. Turn the wheel so that the valve hole is at the top of the wheel.

            DISHED WHEEL: If this is a dished wheel with an inboard disc rotor on the left side, the SHORTEST spokes goes on this side. Put the longest spokes away so you don't mix them.

            The second group of spokes goes into the hub from the OUTSIDE of the flange on the LEFT side of the hub.

            Install one spoke at a time.

            THE FIRST SPOKE: This spoke is important so be careful. The first spoke of the second group (the 10th spoke) should go into the rim just to the LEFT of the key spoke (looking at the wheel from the left side). Hold the hub straight, and you'll see which hole in the hub to use. This spoke should not cross the spoke on the opposite side.

            OFFSET HOLES: If the holes in the rim are offset, you should put the second spoke in so that there are spokes in the two holes to the left of the valve stem hole.

            (When the 10th spoke is installed, the rim should have to spokes next to each other next to the valve stem hole. The key spoke and the 10th spoke must not cross each other)

            NEXT 8 SPOKES: Install the other 8 spokes in this group following the same pattern.

              PART II

              The third group

              Look at the wheel from the RIGHT side.

              DISHED WHEEL: If this is a dished wheel with an inboard disc rotor on the left side, the LONGEST spokes goes on this side. Put the shortest spokes away so you don't mix them.

              TWIST THE HUB: Twist the hub CLOCKWISE so that the spoke next to the valve stem hole is angled away from the valve stem hole.

              THE FIRST SPOKE: The first spoke of the third group goes into a random hole on the RIGHT side of the hub from the INSIDE of the flange. This spoke should point in the opposite direktion of the existing spokes. It crosses over to spokes and goes under the third spoke on the same side of the flange. It goes into the rim next to a spoke from the other side of the flange.

              The fourth group

              Look at the wheel from the LEFT side.

              The spokes gos into the wheel following the same pattern as the third group.

                New wheelbuild:

                Rim: Surly Clown Shoe 26", 100mm wide, 32 holes
                Hub: Nimbus ISIS Disc Steel Hub - 32 Hole (125mm)
                Spokes: 14 gauge black, 259mm/262mm
                Frame: Nimbus Hatchet

                The first challenge is always to get spokes the right length. I told UDC UK what I was building, and Nick got me the exact right spokes, so no problem there.

                Lacing a 32 hole rim (3 cross) is exactly the same as 36, except there's 8 spokes in each group instead of 9. The spokes in each group goes into every fourth hole etc.

                This rim has 64 holes (2 on each 'row'), so I could just choose the hole next to the valve stem hole. Of course there can only be one spoke on each row.

                I thought a rim that wide would be true right away, but it was completely off just like any other rim.

                The hub has an inboard disc, wich requires an asymetrical wheelbuild (dished wheel). The Clown Shoe spoke holes are not offset like the Nimbus 80mm rim (new Hatchet). The Nimbus 80mm rim therefore requires a symetrical wheelbuild even with an inboard disc. Very clever.

                Anyway, this is where the trouble starts (there's always something). I could not get the rim centered in the frame. When I got the correct spoke tension on the disc side, the spokes were almost straight. So when I brought the spoke tension up on the non disc side, the rim got even more off center. I ended up with the rim 18 mm from the frame on the disc side, and 8 mm from the frame on the non disc side, and spoke tension 25/19 on the Park Tool. It turned out that my orignal wheel (Surly Marge Lite rim 65mm), was off by 10 mm too, I just hadn't noticed with the narrower rim. I put a Schwalbe Jumbo Jim 4.8 on, and it looks like I've got enough clearence.

                Will the offset wheel be an issue? I would very much like to hear others experiences with this setup.
