Pads: Koxx Greens Time used:about 10 mins (will edit when had a proper ride) Rim used: Echo 2007 Grind: Sure thing - Light Brake used: magura standard hosing etc, Echo booster, Water bled. What is your opinion of a working brake: Nice and bitey, Shed loads of hold. Nice noise helps REVIEW: Set up the pads, all square, and hitting at the same time. Had a play in the garden with a few back hops. The seemed to work well. Went and had a play about on a few curbs, Never slipped. So i had confidence in them and moved ion a 6foot gap, pulled it off 1st time, pads just held. dont seem to too bad. Only thing that would make them better is noise, at the moment they make a swooshing noise, but yet there pretty bitey. They need time to bed in so I will edit when I have had a half decent ride later on to night. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Pads: Coustsinks Time used:Good few weeks Rim used: Echo 2007 Grind: Sure thing - Light yet sharp Brake used: Avid SD7 Vee brake, Clark cable. No booster. CNC backing What is your opinion of a working brake: Nice and bitey, Shed loads of hold. Nice noise helps Review: These pads are they best pads I have ever use, They tick all the right boxes for me. Never failed once on me. Used them for a good 4 weeks with the same feel through out. No lack of bite and hold when the grind got used. Only thing that I didn't like is that the pads weren;t touching the rim correct. which was a bummer.
