Rider weight is the main issue, lose weight get fit go faster. Few grams and loads £ isn’t the answer. Changing tubeless is a pain and gets worse with older tyres. I do have DHF/DHR, but tend to only run HR2 and Hans Dam, they are pretty much do it all tyres setup.
Go carbon and then change tyres only when I really need to. Maybe once a year – summer/winter, what I do. Cant understand why buying two 1700 sets of wheels, cassette and tyres is cheaper than a good set of carbon and to save a few grams.
Did Trans rockies on 2.3 HR2 front conti 2.2 trail queen. Here in UK HR2 Hans/Damf 2.3 for pretty much everything. Bomb proof, light, reliable. They are more important to me. Don’t think saving a few grams makes you any faster. Its the rider. Carbon is also stronger than alloy.
