|I'm getting sick and tired of stretching out chains every couple of months on my Surly Steamroller. I'm using a 3/32" setup and have tried Shimano and Sachs/SRAM chains. I'm currently trying a KMC Z chain. My question is this: Will a 1/8" setup give me better life on the chains?
I saw a Steamroller in Washington, DC today with a 1/8" setup. The chain looked like a KMC Model 410H (heavy duty BMX chain; the thing was huge!). The bike had a QBP 1/8" chainring in the front and I couldn't make out the cog in the back. If I wanted to go this way, can I order everything via QBP at my LBS? I'm using a Shimano 600 road crankset and a Suzue flip flop hub.

|I run 1/8" chains exclusively on the cruiser, and replace 'em every 2000 miles or so, more often than most riders here report.
I've finally decided chains are cheap. Being a cheapskate at heart, it took some attitude adjustment.

|How well does a 1/8" chain mesh with 3/32" rings/cogs?|

|The cruiser's what BMX hardware was derived from, all 1/8" chainwheels and cogs.
On second thought, I've been known to run 3/32 cogs on it ... they ran OK. They wear out kinda fast compared to the original cogs (how's 25,000 miles grab you? The original rear sprocket would still be in service if I hadn't finally worn out the coaster brake's flanges.)
The original chainwheel (chromed steel) is still in pretty good shape, although the drive pin hole is a tad elongated. I recently picked up an identical NOS chainwheel to replace it.

|I'm using that set up on one of my single speeds. It works fine but it's noisy.|

|You might be interested in a bit larger chain...

|Will that chain fit a 1/8" or 3/32" setup (or are you pulling my leg)? Where can I order one?|

|Heh heh. That was a joke. It's a Kink fat Boy 3/16" which won't fit on 1/8" or 3/32" stuff, but if it did, it would quickly destroy everything it touched. I'm sure, tho, if you want to run that chain, there are plenty of BMX parts out there that would accomodate your needs. You might have to freeze a freewheel as I don't know of any cogs that big.|
|How loose is your chain?||PODIUMBOUNDdotCA|

|If you have the chain too tight it will cause increased wear on both the chain, chain rings and cogs. If you can master how to perfectly tighten the chain so it'll be loose to the point where it will still not fall of you'll be set to go.
Anyway if you have this down pat my guess is 1/8" would have to wear slower.

|It's not so much that the chain is loose, but that it stretches. I replaced the Sachs/SRAM chain with the KMC Z chain this weekend and the Sachs/SRAM chain was a half link longer and stretched to the point that the rollers were beginning to hit the chainring teeth in a bad way. The chain was only about 3 months old. I use a Redline chain tensioner so I usually adjust the chain in the middle zone between too tight and too loose. It has about 1/2" to 3/4" of play (as recommended by Sheldon Brown).|| |
