A frequent poster here who I have not seen in a long while did some pretty detailed testing changing out steel and carbon forks which on the same bike gave me the idea. Being a retired engineer tinkerer I swapped out my Colnago Master fork for a Tommasini Air Fork, same wheels, stem, etc. I am sensitive due to arthritis in my hands, wrists, one knee and back and have to ride a recumbent trike on bad days. I could not detect any difference in the forks. This reinforces my contention that good frame/fork materials, each with a different physical properties, Gilco, Columbus EL, etc., can be made as compliant or ridged as a competent builder wants.
