When it breaks or starts causing issues such as jumping off of cogs.
So basically you wait until it's too late.
When it exceeds the stretch limit indicated by Park Tool CC-3. I check at least 4 different sections of chain, since they can stretch unevenly. Chain life varies widely depending on usage and quality. I've gotten over 5000 miles on road chains on geared bikes and only 500 miles on my cross bike.
What are you using for your track bike? What has been the best in your experience (not in regards to price).
I try to replace before it measures 12 1/8" pin-to-pin under tension. I don't keep a good enough mileage log to vote, though.
1980ish Free Spirit Sunbird fixed * 1996 Mongoose IBOC Zero-G * 1997 KHS Comp * 1990-ish Scapin * Lemond Buenos Aires Triple
I just hit the 2000 mile mark and measured my chain with a ruler. Seems to be off by 1.5/16". Trying to find my next replacement.
Ah, I guess not many people have computers on their SS/FG bikes. I put one on all my bikes.
What are your thoughts on the screw on master link? Does it work well for you? Are you continually tightening every week? Any downfalls to that type of masterlink? Could I not use a master link at all?
No idea how many miles I ride, never checked my chain for wear. I've been riding the same chain everyday for about 8 months now, maybe I should take a look.
never ive had my sram pc-1 chain for 8 months and countless miles...il get it checked today at the lbs..i take care of it and it runs super smooth so il replace it when it breaks
All these people who say they'll wait for the chain to break usually end up breaking more than just the chain... Darwin awards all around!!!
I do what TT does but with the park CC - 2
but i'm slowly starting to up my tools. a chain measure will be soon, after some bb tools..
On the geared bikes I only replace if I notice detrimental shifting. I'm a bit more cautious with the narrow 10sp stuff since I've seen a few of those snap during rides. But on the ssfg bikes I don't see the need to regularly replace. I've never seen a chain fall or snap on a ssfg under normal use.
i won't deny it i'm a straight ridah
EDIT: I just realized that's a BMX bike.... lol that's a joke for riding brakeless no offense compared to a 700C bike; unmounting and just using your feet to foot brake without wrecking is so much easier.

I usually replace mine about once a year regardless of whether is needs to be replaced....safer that way
been riding my izumi chain for 2 years. still going strong.
Shiiiit. I lube mine once a week and clean the whole drivetrain with simple green bi-monthly.
i would hate to have the chain snap on me when i'm out of the saddle trying to get over a steep pitch...that would be bad
