Pads used: RimJam Green compound Brake Setup: Magura HS33 Race line, 4 bolts, Echo Control booster Time Used: since 07/05 Grind: Very deep cuts on one side Other Pads Used: Local pads, ZOO! Green Tar: Yes, + rosin, resin Performance: When I put them on, they worked great. It's a hard compound so it gives a great feel on the brake. Slight wear after 6 months of riding on a ground rim. The brake is faily strong, but much weaker compared to the Zoo pads. Pretty poor when it's wet, not too good on a smooth rim. Also the shoe (or whatever you call it) fell apart quite quickly, the teeth broke off. That resulted in play. Overall: These pads are adequate, but I wouldn't reccomend them.
