so why pay a lot more for little weight reduction.
Well sure, a little weight reduction on the wheels translates to a lot on the trail. Try sticking some dh tubes in and going for a trail ride, then swap em for some latex xc ones. You will notice a difference. I reckon it’s well worth trying to save weight off the wheels, not necessarily off hubs but certainly on rims/tyres/tubes within reason.
You’re preaching to the converted as I agree but the difference between xc tubes and dh tubes is negligible compared to a ‘light’ wheelset which is strong and a very light wheelset which is as strong.
Hence the ‘cost’ question.
Cost an issue – Hope Hoops and tubeless
Not an issue – Carbon whatever and tubless.
