The 2008 cadenza is medium weight, about 28 lbs undressed, more with rack, fenders , lock, lights etc. The compact style frame is a harder to shoulder than a traditional on but I can carry it upstairs without problems. Im not sure I could do that with a waterbottle installed.
The folded size is quite wide, I dont fold mine on a daily basis, just ride it as a regular frame.
The singlespeed version is a lot lighter (23lbs) and you can play around with 3 speed hubs, or 1x9 speed if you dont need the full MTb gearing. It is a very versatile and tough
frame and you wont be disappointed if you get one.
