Chain Length

[ianrauk]

Just replaced my cassette and chain. I have gone from a 27 to a 25 cassette.
Using the Zinn method of chain length calculation, ie Chain around large cassette and large chain ring + 1 complete link (the KMC quick link as half of a 1 link), but it looks a little too tight in this configuration (large/large, not that I use large/large much anyway)

What does the panel think?

 

[Yellow Saddle]

Too tight.

 

[ianrauk]

Too tight.

another full link?

When I changed my cassette 28 to 25 I took out 2 links I think .yours does look a bit tight

As that bike is obviously too clean to have ever been ridden, I wouldn't worry.

 

[ianrauk]

New chain, 1 more full link.
Better?

 

[Tim Hall]

Much better. What's it like in small-small?

Usually big ring big sprocket plus2 . 2nd looks better but not "right"
