Very kind of you - I would like to try it out first before buying anything. but really I'd quite like a bit of project for the dark Feb evenings so would like to build them. But let me know what you've got on Monday as I'm sure I can find something to tinker with.
I've got an unused wheelset doing nothing at home that you're welcome to borrow to give it a try, if you want, and buy if you like it?
Edit - actually they're disc and as such may not have a rim brake track. I can check once I get back to London on Monday evening.
