Not all folding bikes are a compromise, by any means.
When you have companies like Bike Friday out there offering custom, high end folding bicycles with all out components and excellent engineering, a good folder like that can make a lot of normal bikes seem like a compromise.
Personally, my Pocket Llama rides better than my Rocky Mountain Hammer, and better than many, many others i've tried and / or owned.
There are lots of other great, high end folders out there, ones that can give their bigger equivalents real scares.
My personal solution for fitting the Llama in a thin closet was simply thinner bars. But those Oredon security stems look like a theoretically great solution, it'd be nice to see something on them in here.
