I just took a look at the wheel set. They are a brand called Wolber. They're made in France. They also say "Hard Anodized" "GTX 2" "700 Brake Micro Flashing Treatment"
The tires say Prologue VRS 700x19c Hook Bead Rim. They also say Schwinn in very tiny type. The "Hook Bead Rim" I assume confirms that they are clinchers and not tubulars as I thought. Is that right? Does anyone know anything about these rims? Are these rims any good, and can I put fatter tires on them?
Any one else care to chime in about the worthiness of upgrading such a bike.
Thanks again for all your input.
