Gemeral ROAD bikes'Front derailleurs are designed with an angle intercepting chains by reference of standard chainring ratio 50/39T.
However, when upgrading to other ratios like 50/34T (Compact Cranks ) or 56/44T (TIME race),
This angle becomes uncomfortable when trying to shift between chainring.
RIDEA as a professional chainring producer, has found that an additional angle of 4°will much help solve this problem.
Price is only for one,not a pair, you should confirm you really need what and then go buy
