I need a new chain.. please advise

I just read up how to measure my chain, and it seems like it time for a new one.

I'm new to this, so any advice would be appreciated. I like the SRAM power links for their ease of removing and cleaning. Plus I heard the Shimano pins are expensive.

I have a Shimano 7 speed freewheel, double Biopace chain ring. Are there any compatibility issues here if I go for a SRAM? or do I need a shimano? Is biopace an issue? What about chain length and material? Anything else I should think about?

Thanks!

I highly recommend the Sram PC-58 for all 7-speed applications.

Biopace has nothing to do with it. http://sheldonbrown.com/biopace

You will need to cut the chain to size, as explained at http://sheldonbrown.com/derailer-adjustment

All chains are steel.

Is there something specifically better in the 58 vs the 48 that warrants the recommendation?

There is very little difference in performance, if any between any of the SRAm chains. The surface anti-rust treatment is better on expensive models. I have used the 48 on an all-weather commuter with no problems at all.

The 58 is shiny and the 48 is black. Shifting performance is the same. The anti-rust treatment is probably a mute point if you keep your chain well lubed.

Yeah the 48 has a tendency towards surface rust. No such issues with the 58.

There used to be some titanium chains on the market. If Sheldon says there aren't any now, you can bet money on it.

Wipperman offered one for a while and when it was available, Performance listed them for $400! Any guesses why they didn't sell in large numbers? I haven't seen it listed lately.

If that new chain slips on the smaller cogs on your 7 speed freewheel, it means that it is also worn and you will need a new freewheel as well. Try it 1st. If you need a new one, they are readily available and fairly inexpensive. Hopefully you have access to the proper freewheel tool or a good LBS. Good luck.
