Strengths: Great stopping power. No squealing or chatter.
Bottom Line: I've tried alot of different pads over the course of the last 6 months trying to find a pad that doesn't squeal. I've tried the usual toe-in, toe-out, no toe, with too many pads to mention. Finally, I found a brake pad that works perfectly with no squeal or chatter. These pads are awesome and worth every cent.

Strengths: Works well in wet or dry. Great braking power.
Bottom Line: Works really well. This pads really do work well and will dramatically improve your braking in both dry and wet conditions. For those of us still using V-brakes, these pads are a must.

Strengths: There is not much to say except that after trying everything under the sun, these are unbelievable...period.

There is nothing that even comes close to the stopping power.

I have lived with brake squeal for years and not only are these super quiet, they stop like throwing out a 50lb boat anchor.
Similar Products Used: everything and I DO MEAN everything
Bottom Line: I can't say enough about the fact that after literally years of trying different brake pads these are not only the ones that do not make any noise, the stop like nothing else available.

If you have had problems with poor braking and/or squealing of any kind with rims these are the ticket.
