Technology:

SLR-EV
SLR-EV rim brakes from Shimano feature a symmetrical Dual Pivot design with short brake arms. These reduce friction in the joint area, which ensures better brake response and operation. Two bearings and a roller are used to make the joint area as efficient as possible, and to facilitate the dosage of braking force.
