Hi All,

New to the forum. I am trying to get back into mountain biking. I have an older K2 Proflex 4000 in great shape that I just got tuned and I am starting to ride again. I am a bit heavier than the last time I rode it and want to change out the springs. I have Noleen Cross Link ELT's in the front and Noleen NR4's (I believe) in the back. The springs are rated 130-170 lbs in the front and up to 140 in the rear. I would like to change them out to ones that are good for my weight (215 lbs). Noleen lists their part numbers for the correct springs in the K2 manual, but I am hard pressed to find anyone that sells them for this antique.

Noleen can't help me, I am hoping one of you kind folks might be able to point me in the right direction for replacements or substitutes.

Thank you in advance.
