Hi Folks,
I have an AMP B4 with an F4 fork.
I am only getting about an inch of travel.
If I put all my weight on the handlebars, I can just make horizontal the top parallel linkage of the fork. The bottom of the steerer tube doesn't come anywhere close to the rubber bumper which is located on top and at the front of the bottom parallel linkage. There is about another 1.25" inches of travel available between the bottom of the steerer tube and the rubber bumper.
If I put all my weight on the saddle, about 1 cm is exposed of the shaft of the rear shock.
I have no pre-load set at all in either the front or rear.
With one spring removed from the fork, there was about 1 cm more travel. With both springs removed I was able to compress the fork totally which indicates there is no blockage in the dampers.
The Springs for the fork are rated at 350 pounds and I am 130 pounds, what should I go for? Springs with a rating of 325 or 300 pounds? Less?
The spring I currently have for the rear shock is supposed to be the lowest rating at 400 pounds. What rating should I go for for the rear shock?
Besides Pohl, who can you recommend for making custom springs?
What are the specifications I should supply them with?
Would it be possible to find "off the shelf" springs that would be suitable?
Is titanium a viable option or are the weight savings not worth the extra cost?
Thanks in advance for your input, Michael
