UK suppliers for 650B road tyres and rims?

Dear LFGSS hive-mind.

I'm putting together a potential urban frame build design at the moment, and I am considering going 650b for the wheels.

I am a bit concerned about general availability of stuff in 650B sizing. Are there any good sources for tyres, tubes and rims in the UK, or is it mostly import?

Ta!

Velo Orange stuff via Freshtripe. Not much generally available though.

Diameter- have I got the right end of the stick with the whole 650B thing when I say that you can use a slightly smaller rim with a larger volume tyre to end up with a wheel that is the same overall diameter as a 700C with (say) a 23 on it?

Velocity A23 are now 650b, I think Pacenti SL23 are available in 650b - Not sure about availability in this country as yet.

If not, any 650b MTB rim will work, Pacenti TL28, Stans, as Jameso Said, Velo Orange do a 650b rim.

Ritchey make a 650b MTB slick which is available from Paligap in the UK

There is a 650b wheelset on sale at the moment, a magnesium titanium mag wheels if that tickles your fancy!

Would you like to borrow my 650b disc wheelset?
