At 14 st, have you looked at the standard Pro II build with Flow rims? Hope Hoops through Wheel Pro sound like they’d suit you perfectly.
Well, no, not really as I’m after light racing wheels 🙂
1900g, 28mm wide indestructable wheels are a different kettle of fish to 1400-1600g race wheels. I’m not a burly freerider, I’m 6’6″ tall with a BMI of 22.6 apparently. I’ve got Flows on Pro IIs on my Meta 🙂 This set would be for a ~22lb carbon Zaskar running narrow racey tyres.
I might just stick on the XT for the moment, it just seems a shame. So much weight is lost in the hubs, something like the Roval Controle looks very similar but with lighter Dt240-style hubs. Maybe XTR would be a better bet, so expensive at the moment though, £400 became £600 overnight.
