I doubt that there is any special internal shaping to suit the spoke ends which is the most likely issue. Even if there is, they look like bladed spokes which make life a bit easier.
If it were me I'd be happy to just get a rim of the right depth and drilling and give it a try.

Low spoke count ones are, like the WH-R 560. Many higher spoke count hubs (like 32 spoke) still use J spokes.biker jk wrote:Shimano hubs use straight pull spokes. They are very expensive. Shimano rims are also usually offset (asymmetric).
If you still like low spoke count wheels, then buy another one for the rear. If you'd prefer something that lasts longer, then it might be worth getting a higher spoke count wheel which usually have cheaper part replacement prices as well.foo on patrol wrote:Ok people, my rear wheel has a split 1cm each side of the nipple.Will it be cheaper for me to buy a new set of wheels or get this one re built. The hub is WH-R 560 and still runs smooth.

If you look at the diagram you linked, under spoke replacement it looks like an offset rim. Also my old 105 wheel has an offset rim as can be seen below.ironhanglider wrote:The rims looked to be a simple V shape like the R500 wheels which I used to own. This document
shows a symmetric rim and I saw somewhere that it was a 24mm depth. As long as you can find some at 20h drilling (I have a helpful contact if necessary) I stand by my previous statement, they don't look to be anything really unusual.

I agree with the spokes, however Foo hasn't mentioned a problem with these, I'd expect that he intends to re-use them. The rims looked to be a simple V shape like the R500 wheels which I used to own. This document

Edit: Grammar.

Yes it is like the Velocity rim. Admittedly hard to see in the photo as it was supposed to be of the hub, but I just felt the profile and it is steep on one side and shallow on the other. According to Peter White Cycles an off center rim is not necessary for a Shimano hub, but still a good idea.ironhanglider wrote:This is an offset rim.
I can't see the offset in your picture due to the flare but a variation in alignment of the holes by a mm or two is not going to make more than a fraction of a mm difference in spoke length. Spokes typically have a useful adjustment range of several mm.
