Shimano offers a set of road brake pads with long life and consistent braking power thanks to their cooling fins. Heat build-up is limited, which makes braking more effective on long descents. L05A-RF pads are compatible with Shimano 11- and 12-speed road and gravel disc brake calipers such as 105, Ultegra, Dura Ace and GRX.We recommend running in the pads before your first ride to ensure the best performance and longevity. To do this, spin the wheel without any load and stop it by braking gradually. Repeat this process about ten times. Running in also prevents the phenomenon of glazing of the organic material, which can occur during the first few heavy braking manoeuvres without running in. Shimano L05A-RF pads are sold in pairs and must be fitted in the correct direction. To do this, the side is indicated on the back of the pad: "R" for right and "L" for left. Sold in pairs with the spring. One pair corresponds to one caliper. If you wish to change the brake pads on both brakes of your bicycle, you must order two sets.
