Spinergy just announced they partnered with BWR and are offering their GX wheels at 20% off plus free shipping with code BWRSPINGX
I have a set on my and my wife’s gravel bike. On my Giant Revolt I’ve rolled into some sections I wish I had my mountain bike and they stayed true and kept me moving. Stupid light for aluminum. Down side is the spokes are propriety fiber weave, it’s how they save a bunch of weight. I put a set of the GXX on my hardtail mountain bike last fall and haven’t broke one yet. The hubs are solid with enough engagement for most.
I’d recommend them as an option to carbon wheels at a lot lower price.
