What I am hearing so far is that there could be issues with lacing pattern and the angle of the holes in the rim. Good cautions, but it would be interesting to hear from someone who has tried it.
2 1/2" is standard rim width for a 19" Britbike wheel. You can fit up to a 4.10x19 tire. I have one on the front and an 18"x3" on the rear where I think up to a 4.50x18 tire will fit if it clears the chain. Comparing these rims to some stock steel rims would be the quickest way to check if the hole angles are similar. What was posted earlier about a 3-spoke cross pattern can not apply to a 40-hole rim and hub, so the angle of the holes in the rim should be the only thing preventing you from lacing them up to Norton hubs. Both of mine (and the previous 19" alloy) were drilled for a 750 Commando with drum brakes and I was able to make them work on the disc brake hubs. I talked Carl Donelson into cutting and rethreading the stock rear Mk III spokes by 1/2" each and rethreading them to use with the 18" rim. He was a litle wary because according to Carl, the spoke threads are rolled rather than cut, but it's been on there for 25 years and never gave a problem.
