The design of road bikes has not changed much in the last 100 years, but in saying that, road bike technology has developed by leaps and bounds.
From the first wooden hobbyhorse that the rider had to push along with his feet things have changed, but the basic frame and two wheels is the same.

Pedals, Gears and Chains
Next the chain was invented, so you could have the same size wheels and the gear size depended on how many teeth you had on the sprockets on the back wheel and how many on the chain wheel at your pedals.
The next development was gears, this meant you could pedal up and down hills, before this you had one sprocket on either side of your rear wheel and if you wanted to change gear you had to stop and turn the wheel round.
Gears changed all this, you could change gears on the move, first there was only three gears on a road bike, now it’s twenty or thirty depending on which chain set you have.
Road Bike Frames
The basic road bike frames have not changed much, but the materials have.
First wood was the only thing available, but for a long time steel was the choice of all, in time it got lighter and lighter, then alloy, titanium and now carbon is probably the most popular material, its light and strong, but expensive.

Like frames, wheels were made of steel, then alloy and now alloy parts with carbon rims, but they are still round and I guess they always will be. All other parts on a bicycle started being made in steel and then alloy and now carbon or titanium.
What Should I Buy?
That’s the big question, well you get what you pay for, so spend as much as you can, buy a road bike magazine, look at the smart new bike, look at what the Pros are riding or go down to your local bike shop and drool at the shiny jewels they have on offer. Buy the bike of your dreams and enjoy your road bike cycling. Frame geometries
