Does anyone reckon this stuff is any good - got some brake-blocks and theirs a lot more available: reasonably priced stuff !

I don't think BBB actually manufacture anything themselves, they just source pattern parts and sell them under their brand name. I have heard their cassettes are poor quality, though no experience myself. Parkers specialise in their gear.
