Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Chainring cog combo- Probably a stupid one...

Hi,

Someone told me that it's a good idea to run an odd tooth number on the cog if you are running an even tooth number chainring and vice versa. The person said it had to do with chain wear over time. Any truth to that, or is it perfectly ok to run even/even and odd/odd? I know that sounds off the wall, but I figured I'd ask. Thanks.

Adam

In general a bigger cog and a bigger ring means less stress per tooth. It also means a longer chain, and so less wear per link. Nothing to do with even/odd.

So, I'm guessing he was talking about skid patches. Consult gearing primer sticky...

Because they don't know what they're talking about.
