Flows are nice rims, even though they've been updated a couple of times since that model. Shimano Deore hubs work well, but I'd prefer cartridge bearing hubs myself.
Just noticed that the ringles also include stans tubeless valves and sealant. Not bad.
Hmm. Think you may be right. Both front and rear wheels are QR.
These are close in price to the ones you posted - as good or betterer?
