Are caliper brakes better than V brakes?
The main difference between dual-pivots and V-brakes is not stopping power (they are equal in that regard), but the amount of cable pulled. V-brakes require more, caliper brakes require less ; and so each must be matched with a brake lever that pulls the correct amount of cable.
