Sorry for all the noobi mechanic questions.
Can I use my Tiagra HG53 chain on a Ultegra cassette? I ask because it says on the spec sheet for the CS-6500 cassette only to use HG92 or 7700 chains. Or is this just marketing?
I cant find it anywhere specifically. I have a feeling that yes, from varrious posts that say use THIS chain or THAT chain, that it does not matter much, as long as its a 9 spd for a 9 spd. Still, I need to confirm.
