i had a dura ace 3/32 for a while and it was great, albeit a little noisy. then, when i upgraded to 1/8, i got a cheap surly cog. that thing was noisy as f*ck. even with a brand new and well-lubed chain it was super loud. now i have a superstar and it is like BUTTER. and if deciding between the superstar and gold pro, get the superstar. the gold pro isn't really worth the extra ~$60.

superstar + super toughness = silence.
