I’ve got a set of Halo Aerotrack rims built to Novatec disc hubs on the Tripster. The rims have no braking surface and are pretty much similar weight to the Open Pro and the hubs are lighter than Hope, 6 bolt, cartridge bearing and not too pricey at all (direct from Hong Kong on eBay). The rims aren’t eyeletted but seem really strong, deep section so they tick your bike tart box and come in lots of pretty colours (tick box again). Mine are black by the way… I’ve done thousands of miles on mine on a bumpy commutes mainly, running 28mm Conti 4 Seasons at the moment. They take a much wider tyre though. HTH.
