Yes - I believe it is 'Urban Legend' .........
.
however, it does depend on the titanium ......... or titanium alloy I should say ...
.
6-4 titanium is just about indestructible .... but I doubt this stuff would be used for a ring ........
.
the grade of titanium frequently used for seamless tubing ..... the stuff used for bike frames (the frame tubes) ... 3-2.5 ... is more than likely the stuff that would be used to make a ring .... this stuff is not too difficult to work with ..... I have cut this tubing with both a tubing cutter and a hacksaw ........
.
I know of one place that used to offer Ti rings ........ Boone ...... a high end bicycle component manufacturer ....... I believe Boone is located in Georgia ....... Boone is primarily known for titanium cogs - but they have offered Ti rings and earrings (really neat - micro sized chainrings and cogs) ...... Boone usually runs an ad in the back of VeloNews .......
