He also needs some kind of bearing in the two pivots. Several people said a ball bearing there (like a regular bottom bracket bearing) is a poor application for ball bearings because of the high loading, rain exposure, and small range of rotation. A better idea is a bushing of Delrin or some similar plastic. Mark also thought the whole swingarm approach could be replaced with custom built frames that would have better triangulation sideways, lower weight, and light ball end joints rather than larger bearings.
