There's a reason the 520 is an iconic model. Sure the earlier lugged ones are more "desirable" because we all know lugs are cool, but the fact is that the later welded frames like yours are every bit as good and in some ways better. Full DB chromoly frame with nice geometry - you'll love riding it. Quality of construction is usually very high.

It's a very flexible bike and you can do a lot with it. Fatter tires and it's a gravel bike, skinnier tires and it's a road bike, medium tires and flat handlebars and it's a hybrid. Plus you can carry stuff and go on adventures, if you want to.
