Shimano tárcsafékadapter

The Shimano Post Mount adapter allows you to mount a large 203 mm brake rotor to your fork or frame with a 180 mm direct mount. This lightweight aluminum adapter delivers significantly more braking power, improved heat dissipation, and full control on challenging trails. Perfect if you want to upgrade your brake setup and get the maximum braking performance from your Shimano brake system.

Why this adapter will change your driving style

A larger brake rotor means more leverage and therefore significantly more braking power. The adapter adds 23 mm to the standard 180 mm mount, allowing you to upgrade to 203 mm rotors. This is especially important when riding long descents or needing maximum control on technical terrain. The additional surface area of the brake rotor also ensures better heat dissipation during intensive use. The best part? The adapter is made of high-quality aluminum, making it extremely lightweight without sacrificing strength.

Universally applicable

The adapter works on the front and rear of your bicycle. It's compatible with the post-mount standard on forks, frames, and brake calipers, and fits all Shimano post-mount brake calipers. Installation is incredibly easy. Steel screws ensure a secure fit and long-term reliability.

Here's what we think about it

Users report that this adapter delivers exactly what Shimano promises. Mounting a 203 mm rotor is now effortless. One rider writes enthusiastically: "Does what it's supposed to, exactly as described." Its practical relevance is particularly impressive. If you previously encountered limitations with smaller rotors, this adapter will be a game-changer. Another user, referring to their previous 20 mm adapter, says: "When mounting a 203 mm rotor, it's no longer sufficient; this adapter is necessary because otherwise the rotor rubs against the bottom of the caliper slot and eventually locks up." This demonstrates that this adapter isn't just a nice-to-have, but the essential solution for anyone truly wanting to upgrade to 203 mm. The robust aluminum construction with steel bolts guarantees long-term reliability, even under the most demanding mountain biking conditions.
