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?

When chainring dies

What is the lifespan of an average chainring? How often should they be replaced? What are the telltale signs of undue wear and tear?

The teeth get pointier and develop a "shark fin" look.

The chainring that came on my Sugino track cranks lasted approx. 6-7 months. The chain was digging into the front and back of the teeth creating lips. I replaced it with a Salsa chainring, so I'll see how long this one will last.

If you grab a steel one it ought to last way longer than the alu ones that are standard now. Pull one from an old bike if possible and save a lot of cash.

Check your chain for wear on a regular basis and your chainrings will last a long long time.

I've only had bad luck with chainring wear with a Salsa 48t. It wore fairly quickly, and got not-so-flat as well.

the chain should wear at the same rate as the chainring so check to see if your chain is stretched out. Mileage varies wildly; high-end chainrings are totally worth it.

use prolink regularly and make sure your chain tension isn't too high. otherwise the **** on your chain acts as a grinding paste.

also depends on your chain tension- too tight and wear will occur much more quickly.
