5700 105 casette options

[cpelser]

Hi guys

 

Friend bought one of the BMC granfondo's off the VeloLife auction.

 

Came exactly as per online specs, except it came with an 11-25 casette which he doesn't feel ready for.

According to online specs it should have come with a 11-32 casette. (As per specs below)

 

I see online that older posts says 10 speed 105 can only accept up to a 11-28 casette?

So which will work, 11-28 or 11-32?

 

He'd like to have as much granny as possible.

 

Thanks guys
