This is my second set of Shimano's metal disc pads, which have excellent stopping power for the price. They installed in minutes on my Cannondale CAAD 12 disc, putting the stopping power back in my Shimano hydraulic brakes. As noted in the title of the review, they tend to be louder than resin pads. If you're not bothered by the noise (I'm not), and want to stop efficiently, go with these. I reduced my rating from 5 to 4 stars simply because for some they might be too noisy for some riders. I definitely recommend.
The bars have a flat (not aero) top section that made it a little tricky to get the position of the top and drops perfect at first but not a serious issue. I was unsure of the 12 degree flare but its proven to be the perfect amount for a more comfortable ride on road!
