I recently picked up a few 5mm x 10mm x 4 mm spacers in an attempt to find an A-bearing blank. ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/b/2/b/b2b11d6620cc677c17f7d4b6cadf5a9a44da3715.jpeg) The spec on the inner diameter is 5.3mm -0/+0.3mm while A bearings have an inner diameter spec of 5mm. I bought a few because I knew fit would be loose, but I hoped to find one that had the least “play” and try with that. I threw them on a bearing removal tool, and found the one that had the least play and tossed it into my Weekender and so far we have success!! My Weekender is now a fixed axle! ![image](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/f/7/3/f733f0b511cab046a80883a340b4a33839045ef5.jpeg) After a few minutes of play I took it apart to check the bearing posts and I didn’t find any damage, so I’m pretty sure its not acting like a transaxle. Super stoked here!!
