Review by Some PNW Dude

Good quality pads for my single speed
by Some PNW Dude
Oregon

Bought these for my single speed road bike. Much better than the original pads that came with the bike! Night and day difference in braking power.

Excellent replacement

I used these pads for a Shimano 105 brakeset on my Gardin as well as a Modolo brakeset on a Bianchi. They worked perfectly and on the old alloy 700c rims and eliminated the squeal I was getting with other pads. I would definitely use them again.

Great replacement breaks

I had an older pair of brake pads (Shimano 600) that I liked so I jumped at the chance to get the Shimano Ultegra's. They have performed excellently and because I do a lot of hill climbing when I descend, I feel safe with these pads.

Bought this execting to get metal shoe with replaceable pad like Ultegra road brakes, but this a a plastic shoe with the pad glued in - works fine, but not you wil have to change the whole thing when the pad wears out.

While they are not exact replacents for ultegra calipers they are a good set to carry with you incase of a mishap or if someone is in trouble along the road. Good stopping power.

Not very good on a commuter bike...

Lasted 300 miles in Oregons fall weather.

I used the pads on my single speed commuter... The fall weather in Oregon is not the greatest conditions for any brake pad... I ride pretty hard and of course brake hard too. I expected to get a little more wear out of these value pads, but they did a good job slowingstopping the bike. Might be better in summerdry conditions
