Nice. Our T900 (2015? Last year they made them) came new with Bontrager 2.0" which I didn't trust and the store wouldn't do take-off's so I ordered a pair of Schwalbe 'Big Apple' 2.0 to do my own swap. To this day the Schwalbes sit in the garage unmounted! The Bonties have been amazing. Four straight years without a single flat and we are on that bike every single day commuting through downtown Portland, OR with shopping and errands on the weekends. Flatted in the 5th year and I thought they were done. Nope. Not yet apparently. One additional flat since then. I haven't had any reason to consider bigger than 2.0. I have 2.4 on a cargo bike but I doubt the T900 could go any bigger than 2.0 and still mount fenders. We've got to have fenders. YMMV. Funny enough, one of our other tandems is a
Raleigh Coupe (2005) which was the 700C flatbar (converted to drops 2007) road companion to the Companion in those days.
