Not too long ago, when you bought a new road bike, you got fairly run-of-the-mill wheels comprised of decent rims, spokes and hubs. These wheels were reliable and worked just fine. But, they didn't really add any pizzazz to your new two-wheeler.
About 650c Wheels
Some time-trial bikes, as well as some compact, smaller models come equipped with 650c wheels, which are smaller diameter than 700s. These are a little lighter and slightly stronger, and they accelerate faster than standard 700 wheels. But, 650c wheels sometimes ride a bit rougher (smaller, lighter riders can compensate by dropping tire pressure slightly), lose momentum a bit faster and cover less distance per revolution (strong riders will require taller gearing). So, if you're comparing bikes with both wheel sizes, be sure to test ride them to feel for yourself the differences. That's the best way to decide.
The two companies selling road groups are Shimano and Campagnolo and each offers 5 different levels of components. A group is comprised of brakes, hubs, chain, cassette, bottom bracket, crank, derailleurs, shifters and headset (sometimes a seatpost is included, too).
