I bought a set of wheels 2nd hand just before xmas thinking they were pro 2 hubs on syncros wheels. just serviced the freehub & was confused when the hub looked nothing like what was being shown in the video. bit of a search and turns out it's an xc rear hub (pro 2 front).
not really too bothered, but what is the difference? the xc hub looks to be obsolete now - was it just the version prior to the Pro 2?
also, when putting the freehub back on the axle it doesn't 'click into place' and is just held on by the top hat spacer and then of course the QR pulling it all together. is that right??
cheers!
