I’ve owned both and now only ride Fulcrum. The first set were Red Metal 1s. The second set are Red Metal 1 XLs. The reason for the change was new build and needed 15mm axle.
They spin beautifully, are a good weight, stiff and very well sealed. The bearings far out last the bearings in the Hope wheels.
Typical bearing cost is £20 per wheel, spokes are expensive at about £3. The last time I bought them, I bought a bag of 10 so I had spares (I’d only broken one though and soon after sold the wheels).
There are some bargains to be had late summer so if you can I’d suggest waiting. Think I paid £350 for my RM1 XLs in Sept 2011.
