I have to agree that these bearings are awesome. I have almost a gallon of fuel on my current set and they still seem to be running great. I am running them on an X2 with a trinity .24 extech with the reckward clutch. I bought 3 sets of these and still on the first set. I will run these till they fall apart just to see how long they will last. I am very impressed though.
