Shimano RD-2200 rear der. max Sprocket?

[Dan Carlsson]

My rear der. Shimano RD-2200 says this in the spec. :

Max. Sprocket 27T
Min. Sprocket 11T Front Difference 14T Total Capacity 29T

But in your opinion, is it possible to use it with a 28T
sprocket? Even if it says Max. 27T?

And what does Total Capacity means?

Yes. 30 is common, although I had a problem getting that on
one derailleur.

Range of rear added to range of front

Example- rear 11-27 = 16 teeth front 52/39 = 13 teeth

Total of that setup is 29

This number can be exceeded along with the maximum rear
sprocket size.

Thnks for the info!

So if i use a single chainring of 42 t in the front, i can
exceed the max. teeth in the rear by even more then?

If I understand what you are saying, no. Or at least I doubt
it. Maximum cog size in back is limited by the basic design
and geometry of the parallelogram (sp?) of the derailleur.

If you want a more informed and definitive answer, I'd
suggest you pull this question out into a new thread. There
are people here who have tried combinations my mother warned
me against, and yet they have lived to tell their tales
When a question arises in the middle of an ongoing thread,
it can be missed by others.

True, but a longer B-tension screw (or a shim, or put
existing screw in backwards) will allow most Shimano rear
derailers to handle a larger cog (if I understand correctly,
and I'm moderately sure I
do).
