Lower Gearing for Ultegra 11-speed setup Hello I have a touring bike with Shimano Ultegra 6800 shifters and derailleurs (11 speed). 

I have a compact crank with 50/34 chainrings, and I have a 11-32 cassette. 

I would like to get lower gearing for big climbs and I'm looking for the easiest way to do that. 

It looks like the largest cog for 11-speed ultegra cassettes is 32 teeth.
Are 11-speed MTB cassettes compatible with my rear hub? If so, whats' the largest cog that the derailleur can accept?

If that won't work, could I put a smaller chain ring on my crank?
A few options:


You can use a wolftooth roadlink.
You could also move to a sub-compact crankset. There seem to be a few
options for 46/30 cranks, nothing direct from shimano though.


You don't have to resort to a triple.
