Moots apparently had a MTB design that used the Ti chain stays as part of the suspension. Apparently they weren't concerned about titanium fatigue or perhaps they use a special Ti allow that was more fatigue resistant?
There's almost as many different alloys of titanium as there are of aluminum. I've even seen titanium alloy springs in some applications. So I suspect FB hit the nail on the head when he suggested that Moots picked an alloy for those stays that will stand the test of time. The industry has, I hope
, learned a thing or two about the selection of Ti alloys for use in cycle frames since the early mistakes that still make us doubt.
