My thoughts’ll be in the other thread but, I’ve had 5 LB rims (built into wheels locally, not LB wheelsets). Broke one, when it was old and well used, in a big ugly impact that could have broken anything. It’d done amazing tbh, weighed as much as a stans olympic but did an enduro world series, loads of local hard use riding, a load of uplifts- i broke it at bikeparkwales, on the hardtail. Out of warranty/crash replacement but they still gave me a big discount on a replacement, which I used to get my 29er set. Very happy. Just sold the second pair I had built, and still using a 29er set daily. They’re ace imo, not indestructible but nothing is.
Not everyone is so fussed about weight, obviously if you’re not then that’s going to change what’s important to you and what’s worth paying for (I like light wheels, they just feel better). And with the changing prices and the newest, much improved alu rims from DT, WTB and Easton alu is definitely more competitive than it was… If I was building wheels today I’m not sure what I’d get.
