with a pic.
The Cyclepro was an '87, yours looks slightly older. You can probably verify age by finding datecodes (two letters usually) on the Suntour components and matching them at Vintage-Trek.com
Cyclepro and Nishiki were both brands of West Coast Cycle, so there's a common design team, if not manufacturer, at least in the US. The Nishiki models in Canada often varied from US models. Canadian Nishiki were distibuted by Norco, so there is some commonality, but I wonder how far it goes. I have limited Norco serial number data, but so far I have yet to come across any manufactured by Kawamura, who were respobsible for most of the Nishiki.
The bicycle is question is newer than 1987, at least according to my literature. The 1987s were two tone, but not faded, and still used a traditional fork crown

Made from equivalent tubing, a unicrown should be equivalent in strength with a standard fork. In my experience, the weak point of forks are the blades themselves. Basically a unicrown attaches the two blades directly to the steering column, eliminating the cost of the crown. It also eliminates one joint (crown to steering column). I would think that these two factors are larger than the cost saving of TIG welding over brazing, but regardless, when you add them all up there are lots of ecomonical reasons for unicrown. The weight of a crown is also more the weight of the extra length of the blades, resulting in a lighter fork. So you've cheaper cost, comparable strength and less weight. It's an all around win-win situation, with the possible exception of aesthetics. Many, especially the vintage guys, just do NOT like the appearance.
Also, consider that the unicrown first appeared in BMX and ATB before making int's way into road bikes, and that should quell any concerns over strength.
