Cn*carbon on ebay do what you're after. You can definitely specify more spokes for no extra charge, and I think you can specify QR or thru axle. The hubs (d771/772) definitely have swappable end caps to allow it.
Thanks. Have you ordered anything from them before? What was quality like and shipping times? They do seem to offer exactly what i need.
I'm tempted by the uk stocked chinese carbon for quicker delivery but higher prices. A more realistic warranty too.
I've got cn*carbon 50mm disc clinchers. 3000 mi or so with no issues at all. Shipping was 3 weeks or so, took longer as I asked for the 28h drilling rather than 24h. They came with a 'carbonspeedcycle' invoice in the box (another eBay seller), so I guess they're resellers. No complaints though.
