I agree. I like that 1:1 requires virtually no regular tuning/calibration of the barrel adjusters.. in this regard I appreciate it for increased repeatability, consistency..
I still use a Shimano front mech though and cranks.
I have had no problems with my X9 shifters either, I like how they feel, I appreciate the fact you can remove the cover with a little thumbscrew so you can, if you want, apply a little more light grease to the mechanism..
I had X5 previous to X9. I gave up trying to re-assemble the X5 I disassembled. Life’s too short.
I am also a huge fan of Middleburn cable oilers. I have 3 sets. People talk nonsense when they claim these are unnecessary or a cause of gummed up cables. They are brilliant. They allow lubricant to get into the shifters and cables and they blast out crap. They make cables last a long time. My last set I fitted 5mm cable oilers to 4.5mm Jagwire cable using neatly cut heatshrink sleeves. Looks very classy, brown and gold braided cables, brass coloured oilers with black heatshrink sleeves.
