Shimano flatbar brake levers (1 pair) without shift lever function, for fitnessbikes. With 2,5 finger brake lever and SLR-technology. For rim and mech. disk brakes.
Strengths: Stiff, work well, look good with the 770 shifters on my carbon bar...
Weaknesses: What weaknesses?
Bottom Line:
I was using R550 levers which were okay but didn't give me a lot of confidence
when really hauling on the anchors. The R770 levers are so much stiffer and power
is easy to apply as well as they modulate well also.
