Here's one of the things I'm most curious about. The kingpins are mounted straight in to the pivots rather than having pivot balls and, especially in the front where the pin angle from front to back is fairly extreme, it would seem this would be a source of friction that prevents the suspension from working as well as it could. Another rctecher (dajohnwee) offers up the idea that using a 2degree rear pivot mount in the front is the way to go thus decreasing the front a-arm "rake". Any thoughts on this?? BTW, I currently use the black belt and find the action very smooth as compared to my ta05. Do you think the yellow or blue belt would actually be more friction free??
