Hello guys, I just bought a new Blox single bend shifter locally from someone. It has never been installed and is new in open box. I just noticed last night, a few days after I bought it, that one of the bearings is not spinning smoothly.

On one side, there is absolutely no resistance. On the other side, I can feel it catching or grinding just slightly. I see a size number on the bearing, so I'm guessing they are changeable.

Any ideas on how to get it out??

 

mine used the same bearings as a skateboard. just pop the old ones out with a punch

 

The issue is there's nothing to grab with the punch... the inside of the bearing is almost flush with the middle of the hole...

 

There is a hole straight through the shifter though correct? Can you not push a punch through the opposite side at an angle and grab a peice of the lip?

 

That's what I'm talking about. There's nothing to grab when looking into the hole at the bearing on the opposite side. It's flush - or at least flush enough that it will be very very difficult to grab enough...
