I’ve been looking into this for my tarn. I suspect I will probably go for these at 245 a pair https://www.merlincycles.com/pro-build-chosen-hub-alex-xm35-trail-wheels-275-100437.html
Or at the narrower and cheaper end, which may be ok if you’re running 2.8 these for only 200 http://www.chainreactioncycles.com/mobile/nukeproof-neutron-mtb-wheelset/rp-prod160742
Plus you could get another 20 off the nukeproof with bc discount.
I think the halo vapour were reviewed on the main site so may be worth checking the reviews.
I’m trying to wait until conditions have improved til I go plus but I suspect I’ll cave soon!
