SR22 pilot reported nose gear mechanical failure on landing; resulting in a propeller strike. The aircraft was moved to a hangar for repairs.

Narrative

I was out practicing commercial maneuvers and decided to land at ZZZ for fuel. Winds were 300 at 8 kts. per the ASOS. There were 2 other planes in the pattern. I entered the 45 for a left downwind Runway XX. Set my aim point a little further down the Runway to exit Taxiway 1 for fuel at FBO. The plane settled down smoothly on the mains; I started to taxi down the Runway towards Taxiway 1 and the nose dropped; the propeller struck the pavement. The composite blades offered very little resistance; other than the change in sound I could not tell the blades had touched the ground. about 1.5 inches were shaved off the blades. I thought I had a flat tire on the nose gear but the plane continued to make forward progress so I moved off the Runway and taxied to the nearest parking about 150 yards. After shutting down a local mechanic helped me remove the cowling and we saw that the nose gear suspension; composed of 6 rubber pucks had broken; which dropped the nose about 6 inches. It was not a violent event by any means. I sent pictures of the broken suspension to my mechanic who has many years of experience on Cirrus and he said he had never seen that type of failure previously.
