I've reduced the gearing on mine by fitting a 14T Sturmey sprocket (also needs an extra full link in the chain). 64" on Marathon Pluses was pushing it a bit for "normal" gear, although it was only 62" with the Stelvios (which I'll save for closer-to-home stuff). Now I have 44", 58" and 78", which are all quite usable gears - 58" is my do-everything gear on the touring bike.
I've also got the hang of removing the wheels in 2 minutes or so, although I wouldn't like to do it in the dark and wet. The bottle cage works well on the back of the "stem" using the Elite strap-ons (oo-er).
I will bring along a good quality M8 stainless steel bolt for you. The first time you try to adjust the Pentaclip, you'll see why you need it.
