I have an X2 front that I had to buy due to new forks, and not wanting to go up to a massive rotor so have it matched with an old, much needed of an overhaul, mini lever. Performance was much better than the mono mini it replaced.
The looks are love ot or hate it, but the overall finish and levels of workmanship are higher then XT IMO. I bought some elixirs recently and thought they were a bit 20th century compared to the x2s.
Performance may not be mind blowing but good enough, and the workmanship is second to none, similar to high end Magura’s.
