A bike brake adapter that lets riders fit larger rotors while keeping caliper alignment precise, the AEYINO Disc Brake Caliper Mount Adapter. Stronger, more confident braking suits trail riders tackling steep descents and heavy loads. Is the upgrade compatible with your fork and caliper setup?
⚡ At a Glance
- • Mounting Compatibility: Adapts caliper mounting for 180 mm and 203 mm rotors, offered in PM (post mount) and IS (side mount) variants with an F option for front forks
- • Best for: Mountain bikers upgrading rotor size to gain stronger braking on technical trails
- • Not ideal for: Bikes without disc brakes or setups with unknown mount standards
CNC-machined aluminium alloy adaptor allows fitting of 180 mm and 203 mm rotors with multiple mount options. Included bolts and washers, plus user-noted pre-applied thread-lock, help ensure a secure installation.
More stopping power – Thanks to 180/203mm rotor compatibility
Repositions caliper mounting to match larger rotor diameters so standard calipers can be used with 180 mm or 203 mm rotors. Available in both PM and IS configurations to suit common frame and fork mounts.
Greater braking bite on steep descents and when carrying heavy loads, a practical upgrade for riders seeking stronger stopping performance.
Lightweight durability – With CNC-machined aluminium alloy and T6 hardening
High-precision CNC milling produces tight tolerances for consistent alignment, while T6 heat treatment increases material strength and fatigue resistance. The aluminium construction keeps mass low compared with heavier metals.
Durable enough for regular trail use without adding unnecessary weight, offering a balance between robustness and ride quality.
Secure, hassle-free installation – With supplied bolts and pre-applied thread-lock
Mounting hardware is included, with user feedback confirming bolts arrive with pre-applied thread-lock and spare washers. Precise machining helps bolts seat cleanly and evenly.
Bolts hold firmly during aggressive riding and reduce the need for additional thread-lock compounds or extra hardware.
