Features: There are two types of brake pads (mechanical brake pads and hydraulic brake pads). Please make sure you’re purchasing the correct brake pads for your ebike model. VTUVIA's brake pads come in a hydraulic set for the SN100, SX20, Reindeer, Gemini and UL SF20H, and a mechanical set for the SF20, earlier SF20H, SJ26, SK200, Kangaroo and Giraffe. Note: These brake pads do not come with the spreader spring clip that goes in between the pads. Please check your ebike to confirm whether it is equipped with hydraulic or mechanical calipers.
