Perhaps we made the silicon cap covering the wheel on our bearing a little too discreet. We think some of you don't realize that you can lift and take off this cap in order to clean the wheels within each bearing. This is easily done with a cotton tip and some denatured alcohol. With this new bearing technology, it is no longer necessary to remove the carriage from the Glide. This is truly an industry first, way ahead of the game for a bearing that took us more than two years to fine-tune. A bearing upgrade kit is available for those of you who have the previous generation set on your MYT Glide.
