Anyone had a Tange Fusion II Aluminium Road Fork fail?

Why do you ask about those Tange forks?

Just curious, as I have one that looks very similar. Same crown and is aluminium. Bought with a Columbus EL-OS frame. I've yet to finish building it up, but I have had some niggling, maybe unfounded, doubts about aluminium forks in general.

Your doubts about Al forks failing over the long term are hardly unfounded. I have a problem with the way an Al fork can let go with little warning. As a comparison, here's an example of a steel fork that couldn't take the strain, but failed slow enough to be noticed. Suffice to say that I prefer steel forks.

Thanks for posting Rob.
From the brief read I get the impression that 6013-T6 must be more expensive as I'm sure the bike companies already know what lasts 3.5 million cycles, but won't make them as much profit. It appears they are aware that the few original owners who ride far enough to make a frame fatigue fail are a minority.

About 1992 when I heard about (then expensive) Al MTB frames cracking. :)

"Why do you ask about those Tange forks?"

Steel is real & That Tange Fusion II is fitted to a 1989ish Shogun Team Issue.

It was about 40 years ago when the Viscount Aerospace bikes came out as the latest great thing. Then the failures began........



It had a very cool TA crankset and rings though 8)
