Can I chime in ?
We and Gf have a czar each. 2000+ miles, she’s on praxis bb and I’m on pf30 wheels manufacturing – neither have been a problem, and I too want sure about the standard.
I run xx1/x01 and she runs shimano slx, again it’s been a decent experience with only me having some SRAM issues. Expensive cassette bonded itself to free hub after 600 miles, the splines got sheared off when removing. Also x01 rear mech has developed play, both have gone back under warranty.
Frame has been amazing, had some minor issues getting grease in but I reckon that’s because it didn’t need as much as previous Turners.
Just awaiting my enve 50/50s which causes me a lot of grief in the finance / daft spend department but I thpught stuff it.
Mine is nowhere near 21lb despite a light build though but do insist on hope brakes/hubs etc due to durability.
And yes, I’m from the school of having a slightly higher cockpit as I put big long miles on mine and I see no need to be so low at the front at all. (Is this an xc trend that no one questions?)
