The frame comes in two sizes. Mine is an L with a 55.5cm top tube. When it comes to parts, there is nothing funky, arcane or proprietary so customization is perhaps even easier and wider ranging than a
PR.
That sounds better than most folders, many of which make it harder with proprietary parts, but still not as straightforward as with the customized Bike Friday models. AIRC, you send them a set of key measurements from your favorite road bike once you have your fit dialed in and they then make the Pocket Rocket to match so you have the same setback, reach, bar height, etc.
