Literally EPIC
Fast shipping and perfect frame set as described. It's literally the lightest built MTB I've ever felt. My wife will be smashing on it at this year at the Leadville 100. LFG Thanks guys!

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.

S Works Prevail 3 Fits Like a Glove
The S-Works Prevail 3 is one of the most comfortable bike helmets I’ve worn. The fit system adjusts perfectly, and once I ratchet the MIPS cradle to my head, the helmet almost disappears — it conforms so well that I barely notice I’m wearing it.
Ventilation is excellent. Riding in moderate weather around the mid-70s, my head stayed cool and comfortable without overheating. The airflow design really works.
Thankfully, I haven’t had to test the helmet in a crash, and I hope I never do. But the build quality and design give me a lot of confidence in the protection it offers. Highly recommended.
I feel like I bought a used bike with all of the things I discovered when I got it.
One of the SRAM AXS batteries was DOA and Sierra made it painful to get it replaced, so I just bought a new one on my nickel. I had to trash the tires that had dried sealant in them and I couldn't completely clean it out. It should have come with tubes but was converted to tubeless which I wasn't expecting. I paid a mechanic to go thru the build and he found lots of things not right in the assembly of the bike. It is all good now but I did incur additional cost to make it good.
