Shimano's M395 disc brakes are a proven, bombproof design. They're pre-bled, easy to install and inexpensive, meaning they're perfect for the beginner or price conscious cyclist. Don't be mistaken by the price; these perform very well and are a cinch to maintain, making them some of the best bang for the buck brakes out there. Be aware that rotors and adapters are sold separately. Always use genuine Shimano brake rotors and adaptors.
