could someone explain what it means by capacity 37 tooth. it says that i could run a max 32 tooth, min 11 tooth cassette. the reason i ask is that i have bought a bike for the wife and i was wanting to make the bike as low geared as possible with a 34/50 compact chainset.

The front chainring difference plus the rear cassette difference cannot be greater than 37 in total. So your 50/34 front could be used with a 32/11* cassette as 16 + 21 = 37 which is ok.

* or anything between these values.
