track cogs?
Is the width and especially the offset of the teeth from the edge of the
cogs different from manufacturer to manufacturer? If I get my chainline dialed with one cog, do I have to make adjustments when changing to a cog from a different manufacturer? (Shimano, Surley, etc..) Also, can I put the cog on either way to suit my chainline? (on the Shimano I have, the teeth are flush on one side but about 3 mm or so in from the other) |

Sheldon has a table on his website showing the chainline of different cogs. In practice most decent ones (Shimano, EAI) can be swapped over without problems. You can fit the sprocket the other way round if you like, although clearly they're designed to fit with the "shoulder" against the hub flange and some cogs might be machined in such a way that the chain gets uncomfortably close to the spokes. The lockring - if you use one - won't fit as snugly against the cog either. |
