We're working with Alex @ mtbtandems.com on spec'ing out a new ECDM and have had some thoughts and discussions on whether 1x11 has enough durability and range for tandem use. We're a 295lb team that started out on our Fundango with 3x9 and now 2x10, which we've had ok success. On our 2x10 we're running 24/36 up front and a 12-40 rear cassette. I really need to spend some time with a gear inch calculator. My single bikes are all SS, so I'm a little out of the loop on the latest geared grouppo tech. However, my last geared bike was 1x11 and I really liked the setup.
I'm also interested in shimano's new XT m8000 group; supposedly they've made some big strides in shifter feel over the prior versions. With the long cable run on a tandem, shift lever effort always seems to degrade quickly and become increasingly difficult to shift. The Shimano 1x11 group is intriguing also because, I think, you don't have to change the freehub.
What say ye?
