Tiagra Triple Trivia

Fellow Techcyclists -

All the chainrings on my new Tiagra Triple crankset have the same black finish and I thought they
were all aluminum. I decided to find out. Using a magnet I found that only the big chainwheel is
aluminum. The other two are steel. Does anyone know if this is the standard Tiagra configuration
from the factory?

They work great, so it's not a big deal. I'm not a racer or club rider and don't mind an extra ounce
or two. But, it's worth noting for anyone considering them for a triple crank upgrade.

Shimano Sora is all steel rings, Tiagra is steel inner/middle - see

Got to go to Shimano 105 to get all aluminum rings, which is a problem if you need a
non-octalink crank.
