does any body know how much the crankset on a Giant Rainier weighs?
do you think it's a lot heavier than a shimano XT crankset?
is it worth the $$$ to change them?
the stock cranks look beefy, but i don't know what material they're made from. i ASSume it's aluminum, but don't know for sure,. or what alloy. do you?
also, what are the XTs made out of? what alloy?
thanks for the info!
