Picked up a set of ATRx as a replacement for the stock Stan’s Grail on my new VAAST A/1. Holy cow, what a worthy investment. They spin up so quickly! Also took a ton of weight off the total bike. Like other Reynolds I’ve had in the past, they are appropriately stiff and I don’t ever worry about durability. If you are looking for a hassle-free, zero buyer’s remorse set of wheels, these are it!
