They have been and still are a PITA
Google the issues with them
I will be dumping them for next winter (i ride the roadie more so the MTB is a winter toy).
My issues -
Grabby
bleed issues
i can adjust them so they are spot on, remove the wheel and lay the bike on its side for transport and when the wheel goes back in i have to adjust them again.
Some one will come and say they love them, me, they are going to be replaced by Deore as fitted to my hybrid / commute bike.
