as above really. XTR hubs look like a fairly good compromise on cost v weight and if they run as well as my old XT ones have I'd have no complaints. I'll probably go 15mm in the future so would like a convertible hub.

Why not get some Hope Pro3 hubs – convertable to 15mm IIRC. Never heard of XTR hubs being converted from 15mm to QR myself ?

I'm a centre lock fan and never really liked the sound of the hope freewheels. I ditched my old Hope wheelset in favour of an XT set.

Well then I think your stuffed with converting XTR between QR and 15mm sorr 🙂 Unless someone knows any better?

I thought that would be the answer. DT240s hubs it is then. and a HUGE hole in my bank balance.
