Engineering Innovations
Engineered with attention to performance, durability, and compatibility, this master cylinder brings together precision bore size, responsive lever travel, and standard mounting - all in a lightweight and corrosion-resistant body.
Self-Bleeding Hydraulic System
◎ Integrated reservoir design eliminates air pockets.
◎ Dual-path fluid return ensures complete bleeding.
Optimized 12.7mm Bore Performance
◎ 27% more fluid displacement than 11mm cylinders.
◎ 33% reduced lever effort versus 14mm units.
◎ Linear pressure curve for predictable modulation.
High-Pressure Reliability (6.9 MPa)
◎ Quad-seal piston assembly prevents pressure loss.
◎ Hard-anodized bore (Type III, 60μm).
◎ High-temp FKM seals (rated to 180°C).
◎ Zero performance degradation during 24-hour endurance tests.
Pro Rider Ergonomics
◎ Tool-free 6-position reach adjustment.
◎ 17mm sealed pivot bearing for zero play.
◎ Reduced lever effort (35N max force).
◎ Teflon-coated bushing for smooth operation.
