Shimano brakeset hood model compatibility I am trying to find out if shimano brakeset hood have compatibility with different brakeset.

In my specific case, I have a ST-2200 but can only find arround hood for ST-5800 or ST-6600.

Is their a compatibility of hood for different brakeset model?

Thanks!
The hoods are different for different models of levers, but the ST-2200 uses the same ones as the ST-3300. 

The part you need is Shimano Y-6CU 98040. Ask your LBS to find it for you. Alternatively, you can look for 3rd party manufacturers as well but I doubt they will have something for an entry level part like this. Shimano's documentation indicates that the ST-3400 levers do not use compatible hoods (and the style of the ST-3500 onwards is different).
