Re: designing a better kit frame.
the primary reason for using a chain tensioning and wheel lowering system that does not slide is reliability and ease of use. sliding bearing blocks are an ideal solution, however they do just that, slide. i am un-inclined to trust anything that slides in that manner. many bicycles made use an a-centric bottom bracket, one of my team-mates bicycles was actually the inspiration for these. a sliding bearing block makes it possible to over-tension chains very easily. however with these, it will be more difficult to over tension the chain, with the addition or subtraction of a half link, and the rotation of the block, any length of chain can be tensioned.
