Hi, yes the evw2x is an exact match but at those prices I'd be looking at £321 for the 12 I need - Euro Bearings prices are a joke IMHO. The same can be bought in the US and China for £3 a piece. I'd expect to pay £5/£6 with UK prices - but £321 is bonkers. I think I might be able to use U groove instead of V groove so that opens up a few more avenues. They are very common in the US it seems but like rocking horse droppings in the UK. Maybe I need to find a US company that does expedited shipping. Thanks for your help though - genuinely appreciated.
