I am with ThermionicScott (great name) on this one and recon it will be fine.

As well as the half links you can move the wheel by changing the ring or sprocket size. You might have to play around a bit when you first get it, but once you get the correct set up so with a new chain you have some room for wear, you are sorted.

If you can fit a sprocket to each side of the rear wheel (I believe such wheels exist) you could put a 1 or 2 tooth larger one on the non used side. So if you run out of adjustment on an epic long ride just flip the wheel over - you might be pleased of the lower ratio too :-)
