Ready to race or tackle a century ride, the Culebro is fast, light, and built with quality components that will last for years. A sleek aluminum frame and carbon fork constitute the body. Its derailleurs, wheels, handlebars, and other parts offer speed and durability on long rides or races on the road.

I think you need to rethink/define what you consider to be “affordable.” perhaps if you are single person without children or other responsibilities, 1650 is “affordable.” rather insensitive of you.
How is it insensitive? Cycling is not the cheapest hobby. If you want a good roadbike, it’s gonna cost. Buying used might be a better deal for you.
Any recommendations on what bike to purchase for younger scouts, ie, Tenderfoot rank, who want to start biking short distances with their troop?
