lots of braking
Shimano doesn't recommend using 203 mm disc on a UCI type bike because riders can easily "over-brake" and kill, paralyze or give themselves a TBI. I'm using these on a recumbent with a pitch-over SSF > 1.2g so they should be fine. Now I can have braking performance similar to a car instead of having the worst braking performance vehicle on the road!
This disc is also only suitable for resin pads not semi-metallic. The disc I received looks great and runs true! Thanks Cambria Bike
