anybody ever tried to convert there unsealed hubs to sealed? alot of people will say it cant be done,but i used to do it all the time with bmx hubs years ago. just press the steal bearing race out of the hub. then press the correct size sealed bearing in its place. there is a curved area inside the hub that the bearing will have sit on,but i never had any problems,the hubs i used to do this mod with were under extreme abuse with years of ramp and street riding,with not one issue. let me know if anyone has tried this,and what you think.
