I would simply say that any new bike you buy has ALL the gears you'll ever need. That being said do you NEED all those gears. The joke in the ten speed days was every bike you'd see on the street was in the small chainring and small rear cog. And I still see that today on a lot of hibreds. Push both levers forward or click the gear levers all the way and the gear you're left in is the small/small.

i've ridden a lot of miles. And I'm a flatlander. So my basic riding gear is a 67in gear, feeling speedy 78" gear, out on Sunday group ride 88" gear. Thats really all I need. The others come in handy when I find a hill or do some off road stuff.
