Knowing exactly what kind of components you get on a bike is extremely important when deciding on which touring bicycle to purchase.
Let’s look at the types of bike components first, then we will discuss the different options with Shimano.
Some of the components that you can upgrade on your touring bike are (there are others):
Rear Derailleur- This helps when moving the chain between rear sprockets. It takes up the slack in the chain when moving to a smaller sprocket at the rear or a smaller chainring by the front derailleur. Est. Price for a Shimano Ultegra Rear Derailleur is about $100. Here’s a picture.
Front Derailleur- The front derailleur moves the chain from side to side between the front chainrings. Estimated price for a Shimano Ultegra front derailleur is about $70.00.
Crankset- The crankset is where the rider is connected to the bicycle. It is the component of a bicycle that converts the motion of of a biker into the rotational motion needed to move the chain. This is what the pedal is connected to. The estimated price for a Shimano Ultegra crankset is about $250.00.
Bottom Bracket- The bottom bracket allows the crankset to move freely. The estimated price of a Shimano Ultegra bottom bracket is about $40.00.
Cassette- The cassette is the cluster of gear cogs or sprockets attached to the hub of the rear wheel. Power is transferred from the biker, to the crankset, to the chain, and to the cassette. This is where the gears come from. Typical cassettes have 9 cogs, which when combined with 3 chainrings, gives a rider 27 gears.
