I just bought a Checkpoint ALR5.
Looked at options for upgrading the 2kg+ OEM wheels and tires.
I’ve never ridden carbon wheels, so maybe I’m missing out on something wonderful, but I bought DT Swiss GR 1600’s for a little over $500 from Merlin Cycles in UK, shipped to US. Gets me to just over 1700g and a reliable, serviceable, upgradable DT 350 hub. 24mm internal width rim.
I’m sure I’d like a $2500 pair of Enve, or even a budget carbon wheel somewhere in between, and appreciate the benefits over the GR 1600s.
I can afford any bike equipment I want, but my limiting factors are mostly fitness, not equipment related and I’ll dish out for a faster bike and wheels when I’m doing 22mph gravel races. I’m going to spend the rest of the money on a better handlebar and dialing in my fit (lost 30 lbs and in shape now, should spend the $ on a pro fit vs. more carbon parts) and maybe some strength training equipment for the home gym.
If you want carbon and have the means, go for it whether it makes sense to anyone else or not!
Marginal gains, pick your point on the $ spectrum.
