My single speed is running a drive train of a DMR tension seeker, a DX BMX cog and a random 9 speed front chain ring. The SRAM PC48 chain is skipping and is now worn out.

What else is a chain to run? Obviously I can replace with any 7-8 or 9 speed chain, but I was just wondering what else might do. I was wondering if a 1/8 inch chain might work as it should be more durable, and certainly cheaper than a chain designed to shift well. The PC48 lasted 800 miles of winter riding so it was not a bad chain by any means.

Haven't tried it on a single speed but changed to 1/8th chain for the non-derailer chain on my MTB Tandem. Works well and effectively lasts forever! (providing you keep it lubed ;)

i tried a bmx chain on my SS, its well 'ardcore mate - the only problem i had with it was when using the poncy speed linky thing - didnt fit through my Rohloff chain tensioner too well, but when fixed with a normal pin works great!

BMX chain.

looks better too.

1/8in chain might _look_ beefier, but it's probably not actually any stronger or more durable. If you think about what a multi-speed chain is designed to do, running it on a single-speed is hardly challenging it at all...

That said, I've got a 1/8in chain on mine.

I run a BMX chain on mine (because it's gold) and never had a problem. I swear I can feel they're chunkier than a 7/8/9spd chain when pedalling.
A BMX splitting-link might not fit through your tensioner.

BMX chain on mine.
Looks well gnarly.
Gold chains are bling.

The local singlespeed clique came to the opinion that BMX chains break more often than 9 speed ones.

I also need a half-link on mine due to very uninteresting chainstay length issues. Which used to be easier to get in 1/8in. That's easier as in "not actually impossible", of course ;-)

I decided to keep on running a PC48 as it did last for ages, and is easy to fit, and reasonably cheap. I wasn't sure if the 1/8 chain would work on a 9 speed front ring (the chain would be much wider than the actual chain ring). If I change to a thicker single speed specific I might try a BMX chain.

What sort of milage are you getting out a BMX chain out of interest? Of course it depends on how dirty the chain gets and how clean you keep it.

Heaven knows. It's been on there for years, but that doesn't necessarily mean that it's covered a lot of distance :-)

Mike, what ratio are you running, I had a similar kind of need-a-half-link scenario, but managed to get round it by being clever with chainring and sprocket sizing.
