I've tried them all, and this one is the best on the market. Large pulley, washer supported bearing, modular, correct sizing, you name it. The one and only caveat is the actual tensioning screw, wish it had a higher pitch (for our metric friends, it means shorter pitch). But they all like that, so no stars lost :)Tip: before installing, degrease the tensioning screw and put 1-2 drops of blue Loctite on its threads. This will prevent it from working itself loose over time.
