CHOOSE YOUR BRAKE PAD COMPOUND
LP-21 Resin
A good choice for riders who want smooth and quiet braking for daily riding, commuting, and city use.
LP-22 Ceramic
A balanced option for riders who want stable braking, controlled brake feel, and reliable everyday performance.
LP-23 Metallic
Designed for riders who need stronger bite, better wear resistance, and longer pad life under heavier use.
5MM THICKNESS INSTALLATION TIP
These brake pads are 5mm thick.
Some compatible calipers use standard 4mm pads. If your caliper is designed for 4mm pads, please make sure there is enough space before installation.
When bleeding brakes for 4mm calipers, avoid overfilling the system to ensure proper fit and brake function.
BALANCED BRAKING PERFORMANCE
These brake pads provide consistent stopping power in both dry and wet riding conditions.
They are a practical replacement option for riders who want stable all-around braking performance.
