Hi John. Yup. I bought one and I'm waiting for the second batch . . .
Basically, it would appear that the first batch they ordered from their suppliers are 1cm too short on the outer cable sheath (or the inners are 1cm too long) so when fitted the cables have too much free play. In fact, they're so long it's not possible to take up the slack with adjusters either. I made up a couple of spacers and they're working ok ish.
I suspect Wemoto will get it right with the second batch which are due sometime in the next couple of weeks, so I'd hang fire until I post on this forum when I get a replacement fitted and tested.
The good news is they certainly seem well made, no nipples dropping off and what have you, and we really need an alternative to Yamaha OEM cables. I'm happy to pay full price for decent OEM items, but £150... for a couple of cables.
