Whats a Compact Crank set?

For those who are still relatively new to the world of cycling you may have heard of the term compact crank set but were unsure as to what that meant. How does a compact crank set different from standard crank sets and what are the benefits to using one? You may be surprised at what it actually is and the applications for using them, along with who helped popularize them.

As the name implies, a compact crank set is going to be smaller than a typical crank set. It will have a 110 millimeter size, which is significantly smaller than common 130 mm or 135 mm sizes. This in turn allows you to have smaller chain rings, with fewer teeth, as well.

One of the major elements of a current compact crank set is that it's a double crank set, which means it features two chain rings vs. three. The smaller crank arms and configuration make allowance for this without losing the low gear pliability and power of a triple crank set.

One of the advantages of all of this is that you can start shaving weight off of your bicycle. As significant bike riders know, when it's crunch time, 2 ounces can go a ways to making or breaking your performance against the competition and against the clock.

Another benefit to the compact crank set is that you are able to do and maintain higher rpm's when you are climbing because you are staying in a lower gear. This is one of the methods that assisted in making Lance Armstrong such a success in the mountainous stages of the Tour de France. By maintaining such high RPMs he was able to gain a maximum quantity of power and speed without knocking himself out.

Additionally, with less spacing between your gears you'll be able to maintain your pace with much less work thru difficult conditions. This includes sudden changes in wind or changes in the elevation that can affect your pace and your exerted effort.

It's also important to note that the above describes compact crank sets for road cycling. For mountain biking, a compact crank set refers to a triple crank set which has been made smaller to help the rider avoid more obstacles in the course.

Clearly, a compact crank set has many alternative advantages. Road cycle riders can make their bikes lighter and can maintain higher RPMs up hills, while also maintaining their pace in other conditions. A compact crank set can help give you the additional edge you've been looking for.
