Fixed for me.
Most likely. Are they just cartridge replacement or the whole pad assembly?
I only need pads.
Shimano Dura Ace 77/65/5500 Brake Pads (1pr)
Although this item (though out of stock) isn't much more. I don't get it.
Shimano Ultegra 6700 Brake Blocks Cartridge System (1pr)
Did essentially the same ride last evening under similar conditions. This time it was 19.6 mph.
Was the difference attributable to:
(a) Tires inflated to higher pressure.
(b) One or more fewer stops at the lights.
(c) MASSIVE INCREASE IN POWER OUTPUT.
