Anyone tried these

Yep

they are pretty much the best I have tried as far a stopping power goes of any brake that uses the Dia Compe design. Currently I have on my 3 bikes, Brew on Giant, Frm on Look, and Cane creek on other look. All based on the same design just seem Brew works best.

Do use Koolstop black pads on them though as these do add to stopping power.

Thanx for info

I have a set as well. only issue I have had was with oxidation of some of the parts due to not cleaning them properly. Nice simple brake that works and is light.
