HI i am not sure what you are asking but the Univega Via Carisma has stock parts other than the handlebars and stem. It has 700c wheels, currently with 38cm Marathon Plus tires. It has Shimano Exage XL deraillers and drivetrain parts (with exception that the FD was replaced with a new old Exage non-XL FD not too long ago by my mechanic. it has a new chain and cassette. It is 7 speed in back and a triple crank up front. Frame size is approx 54cm and the crank arm length is 175mm (I prefer 170mm but it isnt too bothersome to have 175mm but i prefer 170mm.) If i were to get a Cross check frame i would get 56cm not 54cm, i briefly test rode both in stock buildup mode at a LBS once.
If i am going to improve the Univega as opposed to move its parts over to a cross check frame, what i would do is put on 42mm drop bars, a 100mm Nitto Technomic stem, some sort of friction shifters (either bar end or top mount depending on how much money i wanted to spend), and road bike brake levers.
If i were going to move the parts over to a Cross Check frame, i would also want drop bars and probably a 100mm stem.
Both frames have rack mounts in back and front, I believe.
The Univega frame i think was their best one in their hybrid lineup in 1994 and is probably roughly the same weight as a Cross Check frame so I dont think it pays to change the frame, unless i just wanted a new frame (one reason is the teal color of the uNivega is hideous and it would be nice to have a new cross check frame but those arent compelling reasons for me, i dont think.)
The harder decision is what to do with the Trek bike because the frame is heavier than the Univega one (I think the entire frame is not chomalloy nor is it double butted.) It rides heavier than a cross check i think. The parts arent as good as the Univega's. It has some lower level Shimano parts. It has grip shifters SRAM, and low level indexed shimano shifting and drivetrain. Triple crank. The rear cassette may not be stock because it is 8 speed, and i am not sure it came with 8 in the back instead of 7, i dont know. I know the wheel in the back isnt stock, my mechanic swapped in an old Alex wheel and put my cassette on it i think, a few months ago after i had problems with spokes/trueing the orig rear wheel.) THe Trek has v type breaks , and the Univega has the center pull kind with horizontal cable i think. The Trek is more piglike in riding. i test rode a Cross check only briefly a few months ago and feel it is somewhere in the same ballpark as the Univega frame. I read somewhere online that when the frame was new some people thought it was decent for use as a touring frame (it has rack mounts front and back.) The Trek Multitrack 720 i read online has been used by at least some people as a touring frame too, but doesnt seem to be as well reviewed. It has geometry similar to a Trek 520 i read but is heavier. it has 170mm crank which i prefer over 175.
The Trek wasnt their top hybrid bike in about 1994, there was a 750 and I think 780 above it with lighter steel frames and better components.
