Hello, would anyone like to explain the main difference between the blue and clear bolt bumpers? I've seen them both used interchanged on valves before. What is the preferred setup for the respective valve and bolt combinations? Also, is it safe to say they shouldn't be lubricated?

Blues are for classic valves, the clear for all the other valves. The clear are more durable and can be interchanged down as it were, but it is not recommended to swap the blue up, as it were. There is no need to lube them, but some may want a barrier between the bumper and the powertube. The clear will degrade more, so the life is finite. -
glue the clear ones down. They will last a long timeComment
