howdy folks, need you expertise. For reasons I won't get into, I believed the cages on my TA pedals (on ebay) are of Titanium. I am starting to think they are NOT, and I wish to revise my description as such, or cancel the auction altogether and start over. I'm thinking of scratching a hidden portion of the cage, to reveal silver alloy (or not). I understand the anodizing is very thick and this might take quite a scratch. Also, I understand Ti can be anodized, but that the Ti will be notably darker than the silver of alloy. The box says nothing on it regarding cage composition. I have been informed that Ti cages are not mentioned in any TA catalog. I'm wondering if anyone has ever encountered Titanium cages for their TA pedals, or if anyone knows a non-destructive means of testing for Titanium (another list member informed me that grinding titanium will cause white sparks, whereas alloy will cause few if any sparks). These cages are insanely light. Would Titanium be heavier than aluminum in the same shape and size ? (aka, which has higher density ?) Thanks for your patience and help ! mario girasa Cambridge, MA
