Sorry, I know old road bikes, nothing modern.
My 15 yo son has been riding a recently made hybrid; as he's gotten more into biking he wants a road bike. I've replaced the tires with something more road worthy but he really wants drop handlebars. I have a Raleigh International frame in his size, I'm considering switching over his parts, except for one problem.
Shifting is by "Gripshift" type ring on each side, above the grip on the flat bars. Can those be used on drop bars, mounted up by the stem?
Don't want the expense of those fancy brake lever shifters, though could probably find some indexed downtube levers...
