[QUOTE="greg brillus, post: 78257, member: 597"] David's theory of using shorter stiffer springs is near relevant to what we are doing here, though in David's case, he was deliberately lowering the front end to avoid the link/danger zone. Whereas in this case, we have overcome the geometry issue, and we have regained any lost travel. So as a benefit to this, we are trying to soften the front as much as is practicable, but not to the point of bottoming easily. I feel too much pre-load in this set up leads to the fork assembly "topping out" but on the other hand if we were to use short springs and pack them up as required to get the ride height correct, then the spring rate is getting unnecessarily high. It is this fine tuning if you like, that will give the correct ride height and keep the spring rate as low as we can, though I agree with David's thoughts that at least with short springs you can pack them up if needed. Because it is not so practical for each user to cut springs down, it is best to arrive at say 3 different spring rates with equal overall lengths that can be interchanged where needed, and I know this is what Norman has been trying to achieve. Of course now also is the issue of who upgrades to the bearing in link mod, verses who leaves their link standard ........This appears to alter things as well. Anyway it appears that Martyn's Comet is on the home straight, and it has given the result I was expecting. I know he will be chomping at the bit to ride again, and I look forward to his feedback given the amount of riding he does. Look at it this way Martyn.........You currently have "The best handling Vincent in Victoria" and that is saying something............:). [/QUOTE]
