Here's another (perhaps easier?) question and and update. First on the update.
I think I'm pretty sold on buying a new CarryMe model to take around traveling. It will be my first folding bike, and I think I have reasonable expectations. I'm still a bit concerned with size, but the seatpost, "extension stem" and saddle appear to be easily swapped for more layback and reach.
Now here's the question.
What is the size of the "Extension Stem" on the CarryMe if I wanted to swap it for a longer one? I think I will buy the CarryMe overseas and I'd like to buy a longer stem ahead of time to play with the fit. The pacific website doesn't seem to list the steerer (1 in or 1 1/8 in ?) or clamp diameter (25.4? 26? 31.8?) of the "extension stem". Has anyone tried a longer stem, and does it adversely affect the handling?
