I've got a 15cm stem and some noodles with a stem mounted shifter and reverse brakes you could put on the noodles. Sound perfect? Are you within bicycle delivery of Brooklyn?
Or let us know which kind of what you'd like or if you're entertaining suggestions. To start, I'd suggest not putting the reverse levers on the noodles because that would be bananas, especially with that ultra long 15cm stem.
What stem are you using with the Albatross? You wanna stretch waaay out with drops?, or are you picturing a 0-5cm stem getting those drops up close? I've got a fiver around somewhere that I used to think was short, but it's enormous compared to zeros.
Regardless, happy new year to all!
