That model takes 507 or 520, I have 507. I am not sure the full history of that model, mine is the older version that can't use a front derailleur (thus, I have the Sram Dual Drive) and the older version chainstays have minimal clearance for a wider tire. I tried a 1.75 tire once, the chainstays did not provide adequate clearance, thus 1.5 width is all I can run. The bike as shown has Schwalbe Marathon 24 X 1.5 (559X40), but that tire no longer is available in that width. Since that tire size is quite rare, I have several tires in storage and when I go somewhere like that Texas trip, I brought two spare tubes and a spare tire. I think that they changed the chainstay design when they added a fitting for a front derailleur to allow a wider tire. My older model also uses rim brakes, that model currently is fitted with disc.

Handling. The handling is quite good. Compared to my 26 inch (559) bikes, the steering is lighter, but that might be from a different amount of trail or it might be from less rotational inertia. As far as momentum accelerating or decelerating, that bike is lighter than my 26 inch bikes, so I am not sure how much of the difference in handling is from rotational mass or how much from bike weight.

When I bought that bike frame and built it up, that model with 24 inch wheels was advertised as being a folder that handled as good as a full size regular bike. I like the handling of it, I do not find that the smaller wheel size makes the ride rougher. On that trip in Texas, many of the paved roads were quite rough, you can see in the photo how rough the pavement is. On the first day I had front tire pressure in the high 50s (psi) and the ride was rather rough on my hands but the second day I dropped my front tire pressure to the low 40s and that rode much better.

The tall seat post and seatpost extension means that there is a lot of fore and aft flex that you do not feel on a normal road bike. That bothered me a lot when I first built up the bike, but after riding it for a while I no longer notice it. It now feels like a normal full size road bike to me.

On that trip in Texas, that was a van supported bike trip for a week. The van hauled our camping gear for us and all the cooking gear. There were a dozen riders, I had the only folding bike. The other bikes were a mix of road, cyclocross, gravel and touring bikes. All had drop bars, no mountain bikes in the group. I think my folder handled as well as the other bikes, speed wise it was probably as fast as I would have been on a full size 559 bike with the same tire width of 1.5 (40mm).

I have owned that bike for years, but have not ridden it very much. I wanted to try it for an extended trip to see how it worked out. It exceeded my expectations. I am not sure if I will put racks and panniers on it for a camping trip or not, but I would not rule that out if I could keep my load relatively light. But I have full size touring bikes, so if I was to use that on a camping trip there would have to be a reason to use that particular bike over the others.

As folders go, that is a large bike. To pack that into a case that does not exceed airline luggage size criteria takes a lot of work. To fit it in my S&S case (26 X 26 X 10 inches), I have to pull the fork out of it, crank arms off, etc. It takes about as much work to pack for airline travel as my S&S coupled bike.
