Hey guys,

I have a Diamondback Podium 2 with Tiagra up front and a 105 in the back. I have a triple chain ring up front, and a 9-speed cassette in the back. I'm not sure what brand or style either of the rings or cassettes are.

I need a new chain as my bike sat for some time and has rusted a bit.

I was thinking a dura-ace quality chain, but I'm open to suggestions. In any case, I was having a helluva time figuring out which chain model # to buy. Any help would be appreciated, I found the shimano chart but it just confused me more

Thanks,

The noob
