Defy 1 rear mech advice

OwenB

Hi am looking at a new defy 1 on the cyclescheme, thing is I currently ride a triple and as I live on the edge of the lake district a lot of my rides are hilly. I understand that the new 105 can take up to a 32 tooth cassette if its the medium cage version.
I can't find out which version of mech is fitted so would appreciate any help you may be able to offer.

I know that I should mtfu but at 20 stone I just need some extra support till I get a bit fitter and stronger.

Cheers

Pretty sure it's the medium cage version as standard. The shop you buy from would be able to tell you and stick a 11 or 12-32 on it for you. Give the shop a call.
