Cheers guys. I’m looking at the Merlin wheelbuilding tool and I can see EN521 or EX721 (non-disc). Not sure how a rim can be non-disc.
721 was designed for rim brakes but still works really well for DH due to the balance between weight and strength – for a good while it was what Mavic painted yellow and gave to sponsored riders who used other people’s hubs and didn’t want to use tubeless.
EX729 is pretty much same price – too heavy though? EX325 only a few quid cheaper.
Too heavy – unless you’re a heffer you won’t need the weight or the width or the discness
Also, do I want DB spokes?
Yes no reason not to other than a slight increase in cost – they’re better in every other way
And will an XT rear hub be adequate?
Probably
