Maybe I should have left the old chain on

[deaco...@gmail.com]

I tend to get at least 5000 miles out of my 10 spd chains. I have a wipperman connect link keep the chain clean. Take it off dunk in OMS back on every say 500-700 miles just use cheap 3-1 oil.

So today about 6400 miles on the chain took it off seems to not really be stretched all pins line up on my metal ruler. But I go ahead put a new chain on and works fine no skipping and lining the two up exact same links. Over the whole chain just small difference maybe 3/16.

Now I am kinda of mad I was think I should have left it on I probably could have gone 8000. Tell me I did the right thing going early.

Right. We agree.

Say, did nah yawl tear your penis off on a fence post ?

How'd that come off ?

If you change chains early enough, the cassette doesn't wear down.
10 speed Cassette US$25-40, Chain US$10-40.

Yes, but if the chain isn't stretched?

I just had to replace a cassette because I was watching the chain wear
and it was good. After about 6000km I started to have some problems
shifting. A couple of the cogs in my cassette were worn. But the chain
still tested fine. This is a SRAM 11 speed with stock chain and
cassette. I changed the chain as well. I tested the chain with a ruler
and with one of those chain tools that showed it at .7.

But like I said, if the chain doesn't seem to be stretched, was that
what caused the cassette to wear? And if so, how do you determine
whether to replace the chain?

[DATAKOLL MARINE RESEARCH]

Change both reduce risks

[James]

Keep the old chain. Ride the new chain. When you take it off, compare
it to the old chain. When they are both a similar length, you could put
the old chain back on for a while, and start swapping chains every
1000miles or so.

The cassette will wear eventually, regardless of how often you put on a
new chain.

With so little wear after 6400miles already, you'll probably go
15,000miles using 2 chains and one cassette.

Until now I have replaced the chain on principle every year and a half
or so. However, I recently bought a Park Tool "chain checker" to make it
easier to see when the chain is worn, so maybe the interval will change.
I would replace the chain when the chain checker is at "replace soon"
rather than "replace now".

The cassette will in any event eventually wear out. I change the
cassette (or chainwheel) when I notice that a new chain isn't engaging
properly. Typically after about 3 changes of chain.

Amazon seems to be selling Shimano HG53 9-speed chains for $16.
Divided by a year and a half, or 547 days that is an amortized cost of
about $0.03 a day :-)

I have the Park Tool as well. I usually replace the chain when it says
replace soon also. This was the first time that I went through a cassette
before a chain. First time with a SRAM set up though. Bike is about a
year old.
