Hi,

My wife's new summer bike will have a Shimano 5800 105 groupset with a 11-32 cassette.

On the steep hills my wife would welcome a 11-34 cassette like she has on a winter tiagra equipped bike.

I understand the new Ultegra R8000 groupset can support a 11-34 cassette, does anyone know whether the 5800 105 GS rear derailleur could accommodate that 11-34 cassette?

Many thanks

Chris
