By Special Request

This is a purely informational post about some of the differences between road bikes and time trial bikes.

The biggest difference between road bikes and TT (time trial) bikes is all the effort to become aerodynamic. In TT's, you are not allowed to draft so reducing drag is extra important. The biggest difference are the areo bars that stick out in front of the bike. TT specific bikes don't even have dropped handle bars that you see on typical road bikes. Also, the wheels are special to reduce drag. The seat posts (and other tubing) is often shaped in ways to be aerodynamic. 

I think that a TT bike has a little different geometry so that you can go faster for shorter distances compared to a road bike which is designed to carry riders for longer distances.

Other things that you often see TT racers use are....

areo helment

and skinsuit

Here is a website that gives a little more info about how much time you save for each piece of equipment you upgrade.

That's all that I can think of, but I'm sure everyone will get the idea. Basically, I think it comes down to another reason to buy more toys.
