Bike Brake Pads Resin, sintered, Downhill or Ceramic for Shimano Ultegra, L03A L05, BR-RS805, BR-RS505. Fast Break-in on Mountain-Bike or Road- Bicycle.

I took a chance and purchased these for my Ultegra disc brakes. They were easy to install and I've now put about 200 miles on them. They work great. No complaints. Also, I noticed some other reviews complaining about noise, but I have not had any problem (and I ride a lot of mountains).

I’ve used Hardheaded Ram on a few bikes for a while now and I’ve only had one issue which their customer service team handled flawlessly. These brakes stop well and aren’t terrible on the noise. Great product backed by a great team

Replaced a worn-out set of rear pads in an Ultegra 8000 groupset. They fit fine. No issues. Had a 25-mile ride without breaking in the pads at all. Large group ride, so I was on and off the brakes all evening. No issues, no noise, no complaints. They worked as advertised and I would happily buy them again.

Cheap is cheap....make loud niose on both front and back with Ultegra.....The noise never go away whatever I do...........

Pros:Good fit and good breaking. These fit my Shimano 105 R7070 Hydrolic breaks calipers. Good breaking performance.Cons:The pads seem thin, not sure how long they will last.

While the price point of this product is attractive, the braking experience during rides leaves much to be desired. It lacks the robustness I felt with my previous Shimano authentic brakes, noticeably underperforming in comparison. Installation and replacement are hassle-free, which is a plus. However, considering that braking efficiency is paramount for safety while riding, I'm hesitant to repurchase this product. It’s a reminder that sometimes saving money upfront can compromise essential aspects like safety

Ordered these when my usual Shimano L03A pads were sold out everywhere. The front & rear set of Hardheaded Ram resin pads are about the same as MSRP for a single pair fo the L03A pads. I cleaned my rotors with alcohol and made sure the new pads were properly bedded in before going out for a real ride. I've now got over a hundred miles on them and these pads have been virtually silent. Despite not having fins, I have not noticed any fade on long descents. They are pretty good overall, but I still prefer Shimano. These seem to lack the initial bite I'm accustomed to with the Shimano resin pads and modulation doesn't have quite the same linear feel. Overall, they still deliver confident braking at half the cost of Shimano.UPDATE: developed front brake shudder on these after few hundred miles. Sanded down the pads and rotors and cleaned rotors with alcohol. Shudder went away briefly but quickly returned. Swapped out the pads and sanded/cleaned rotor prior to bedding in. See if we better performance from second set.

I have to admit I was a bit skeptical, but figured for the price I was paying, these pads would be worth taking the chance. Turned out I was worried about nothing. These are high-quality pads, work very well, and so far seem to really hold up to hard braking. Very pleased for the price, and would buy them again.
