I've just bought a bike which runs an X12 rear setup (with Syntace 'maxle').
Does the wheel itself have the same dimensions as a 142x12 hub?
In other words, are a 142x12 and a X12 rear hub interchangeable?
Is the X12 bit just referring to the Syntace (m)axle itself?
Possibly a numptie question I know...
AFAIK they're the same thing.
Yes, Hub dimensions should be the same, so any 142x12mm hub should be fine. (Although you can get a 150mm X12 axle on some DH Bikes, but let's leave that aside for now)
The differences are the axles themselves usually - a Syntace axle has a differet thread on the end to a Maxle, for example.
All 142 x 12 hubs are the same. However, the axle and frame need to match as there are a few different patterns eg X12, maxle etc.
Got it, thanks.
I was just thrown as Hope seem to do two types of hub cap for their Pro2 EVO rear hub ('12mm bolt thru' and 'X12'), which confused me. But now I realise that the '12mm bolt thru' is actually 135x12 and the X12 is basically 142x12. I think.

Yep. Also different kit for EVO hubs versus older Pro 2 - the Evo just needs end caps for 135/142 x 12 - the older hubs need a new axle too
