Is the website description wrong? Look at these pictures.

I purchased a Motobecane Team Track:
http://www.bikesdirect.com/products/...team_track.htm

It says it has the following:
Crank - Shimano Dura Ace 49T Aluminum Track ring (3/32 width)
Chain - KMC Z410 (3/32 width)

So I purchased a 3/32 chain whip for the cog and would not fit. I had to return it and purchased a 1/8 chain whip for the cog and works great.

The website did not specify the cog width but i assume you cannot mix and match 3/32 crank/chain and 1/8 cog.

Can you determine what I have from these pictures that i've taken?




Thanks!

cog looks like a 1/8. So does the chain. I'm guessing they just misprinted the description. You can use a 1/8 chain on just about anything, except maybe some wonky BMX sizes, but mixed 3/32 and 1/8 chainring and cogs in any combo on a single speed doesn't matter.

Also the whip you got might be for the even more narrow 9speed cassettes. I often resort to The Rotafix Method as I don't have a chain whip in 1/8. Good luck sorting it out.

+1 from me. The protruding pins on the chain means it's very likely a 1/8" chain. (Most current 3/32" chains have flush pins.) You've got the bike and correct tools for it. Quit worrying and go ride.
