William Kennedy :
I have 11 months into my 7900 gruppo - 12,000 miles - and Im replacing the original brake pads for another set of 7900s. They have been the best performing and wearing pads I have ever used. Highest recommendation.
Michael Mcgehee :
I have been riding the new 7900 calipers and pads for about 5 weeks. These pads are far better then the 7800 pads. I recommend these over the "salmon" pads most people generally replace the old 7800 pads with.
