[QUOTE="MarBl, post: 121438, member: 4437"] Hi, I am new in the Vincent world, having recently acquired a Rapide, which is non matching numbers and meant to be used regularily. I already studied several threads including this one about the uniqueness of the Gridraulics and I'm definitely in for the next batch of the modified steering stems. But after inspecting the specific setup of my forks, another question about the interaction between damper and fork arose. I found an armstrong damper installed with short eyebolts. Now usually its said, the armstrongs should be installed with long eyebolts. However as far as I understand it, the armstrongs have a reduced travel. I measured 2,4". But using long eyebolts doesnt bring back travel, it only moves the available 2,4" to the lower travel path of the forks, where the main problem seems to be located, the "backward rolling front wheel" necessity causing the brake/fork lock. So given the damper-caused limited travel, wouldnt it be better to use the upper part of the fork travel and therefore keep the short eyebolts? Additionally I would remove both inner springs to get the forks full action in the 2,4" range of the upper part of its travel. It seems less of a problem if it bottoms out occasionally rather then top out, if I understand it correctly. Also the bike is meant to be ridden solo 99% of the time with my 75kg. So I am considering such a setup as a first crude treatment before a modified stem is available and I would be very interested in comments and further advice. Thanks in advance Cheers Martin [/QUOTE]
