I have Avid Shorty 4 brakes on the cross bike. That thing won't stop worth a crap. It is ok most of the time, but on these gravel roads around here these brakes are killing my hands. On a 15% bumpy bumpy descent the hands are already heavily pressing into the hoods and when you squeeze the snot out of these brakes it will kill your hands. I have had to stop in mid descent before just to get my hands working right so I could hold on. Are these typical, good, or bad canti brakes? What would be a good set to get if I need stronger ones? Thanks.
