What does this mean?Pros & Cons
Pros
Each spacer weighs about 13 grams, and displaces about 3 cc's of water in a small measuring cup. Which is good, because an aluminum component should cost at most 1/2 of stainless, while titanium could easily cost 2x stainless.
Highlights

These are so light they’d have to be either titanium or aluminum and i’m not sure i can trust what’s listed

Previous ones i had were steel and rusted badly got stuck to the pedals

The only issue was that the pedal shaft thread bottomed out in the extender so i had to add two pedal washers between the pedal and the spacer

So a crude estimate of density would be 4
