for cheapness but sturdy. go with kmc. in 3/32 810 and 610. but you can run an 1/8 chain no problem. I've done it on my track work bike. no matter what people say a 1/8 is not stronger than a 3/32 tho. you can read al the specs on http://home.earthlink.net/~kmcchain/english/ it even list the tensile strength of each chain. no diff for each pitch.

please replace your chain regularily. i've put off way too long ONCE and broken one.
