Duration Product Used:
Less than 1 month
Price Paid:

Purchased At:
Planet Bike
Strengths:
More initial bite than the "standard" b4 sintered bronze pads. Braking effort substantially reduced. Can't comment about life.
Weaknesses:
Not quite as smooth as the b4 compound. Strangely enough, the c4 compound polishes the rotor more quickly. Sensitive to moisture and dirt. Braking effort increases when brakes are wet. Slightly noisier (not the Avid howl) but more like a hiss.
Similar Products Used:
Avid B4 sintered metal "standard" pad.
Bike Setup:
Specialized FSR Elite converted full XTR.
Bottom Line:
Theres seems to be confusion over what compund is c4 or b4. I'm reviewing the newer pads which I believe Avid markets as "organic" or c4 as opposed to "standard."
Braking effort is greatly reduced at the slight expense of modulation and smoothness.
My review is based on back to back testing of the b4 vs c4, both correctly bedded prior to test.

They work great with Avidd BB7s in all conditions but expect a little wear in mud. Dont worry about replacing you would need many tire replacments before its time for new pads.
