**Tuning Notes: several derailleur cages can fit a pulley with 1 or 2 teeth than the original.
Phased pulleys were born to help chain guide on single chainring systems.
Pulleys with phased teeth (PH) can be applied with benefits of higher shifting precision on standard double chainring systems.
As example Durace has been tested with 12-14PH
