Strong and tough - Dec 17, 2014

I am running these brakes on a fat bike that I commute on 3 times a week. They have plenty of power to drag those huge 4" tires to a stop every time I need to stop ASAP. I have changed brake pads and rotors due to noise from them getting wet and dirty from the commutes. These are a good set and for the price you really cant beat them. They can be hard to adjust to keep them from dragging and if you have to bleed then that is a bit of work also. I have called and emailed Hayes support, great response with accurate step by step instructions both times. If you need good strong brakes and are on a budget get these.

I love these brakes, super easy to adjust and Hayes even helped me with sizing the brake lines. They are super light and look good on the bike.

Great Brake for the Money! - Apr 03, 2014

The Hayes Prime Comp brakes have given me nothing but excellent performance right from the box. These brakes come with semi metallic pads so they were a bit weak and noisy during the bed in process. However, once bedded in, they reached full power and the noise dropped considerably. I would definitely recommend these to XC riders as they are light and durable. However if you choose to ride them DH or AM, upgrading a rotor size would definitely benefit their performance. To top it all off, Price Point offers them at an amazing price for the budget rider!
