We can get it from most bike shops here in UK now. Not really too hard to put on and when you get the knack, it's real easy.
Have to make sure rims are clean and dry first and best to finish off job with a tiny dab of clear nail varnish on join at end.
Come in all colours too. About 7 UK pounds, enough to do a whole bike with a little spare.
Mine are the reflective ones from Frozzie Connections and the ones on the ER6 are from Bryce on eBay. They are a lot thinner than tapeworks but work pretty well. One set came in a roll and the other set came pre-shaped. I suggest the roll, it was a lot easier.
