Currently running the ATRx 700's on my Cervelo Aspero and they are unbeatable. This is the second set of Reynolds I've owned and they once again have proven to be a favorite. Light, stiff, responsive and bombproof. AZ roads and trails are pretty harsh on carbon as well but these things hold their own in the desert!
I have these on my Pivot Vault since April and have already done 2000kms in the Swiss mountains including hammering rocky and rooty singletrails and they're still perfectly true. With the backup of the lifetime warranty too, these are seriously good wheels.
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!
