To install a freewheel, follow these steps: 1 Apply grease to the threads on the inside of the freewheel and to those on the hub 2 Thread the freewheel in a clockwise direction, being careful to make sure that the threads align properly 3 Thread the freewheel by hand until it begins to tighten You can use a chain whip to tighten the freewheel further, although this usually isn t necessary because riding the bike will tighten it

To install a cassette, following these steps: 1 Slide the cassette onto the body of the free hub Find the one spline on the freehub that is wider than the others, and align it with the same wide spline on the inside of the cassette 2 Slide any smaller individual cogs onto the hub If there are spacers be sure to include them in the proper position 3 Grease the threads of the lockring and screw it into place on the hub 4 Attach the freewheel remover to the center of the cassette 5 Insert the quick-release skewer into the center of the hub, and tighten the nut to hold it in place 6 Using an adjustable wrench, turn the freewheel remover in a clockwise direction to tighten After you hand-tighten the lockring, you only need to tighten the lockring about five to ten clicks with the tool Do not overtighten

f you re planning on overhauling your bike, replacing some of its components, or performing major repairs, this part is for you Here we focus on several systems, including the frame and suspension, the drivetrain, the steering system, and the shifting system Although these procedures are more advanced than those in Part II, with this book by your side, you can do these yourself as long as you have the right tools and patience After you tackle the repairs in these chapters, you ll be chatting up your local bike-shop mechanic, watching the Tour de France with a new appreciation, and impressing your friends with your mastery of bike repair and maintenance

Understanding how your frame is built Knowing what to look for in a frame Inspecting a frame for problems Identifying the different types of suspension Adjusting and maintaining your suspension

or all the focus given to other parts of the bike when it comes to improving comfort and bike handling, the frame is given surprisingly little attention, especially considering how important it is to your bike The frame dramatically impacts the personality of your bike its stability, how it handles corners, whether it can carry loads, and how aerodynamic it is It also determines your position on the bike in relation to the pedals, the seat, and the handlebars Slight changes in this position can greatly impact the way a bike rides In this chapter, we take a closer look at the frame and how it impacts the biking experience We discuss how frames are designed and constructed and what qualities you should look for when shopping for a new frame We also provide advice for inspecting and maintaining your frame We also discuss bike suspension in this chapter The suspension acts as an extension of the frame by being an intermediary between the road and the bike to absorb the bumps and jars so your frame and body won t have to Suspension is found on more and more bikes these days, so understanding how suspension works and the steps to adjust and care for it is a good idea if your current bike doesn t have suspension, your next one just might

Although there are a number of different frame designs, some more strange than others, the diamond shape is most popular In this design, there is a main triangle that includes the following: Head tube: The head tube is where the fork connects with the frame and where the headset sits to enable steering Top tube: The top tube connects the seat tube with the head tube and can be horizontal or angled up or down, depending on the style of the bike Cables are frequently run along the top tube Down tube: The down tube connects the head tube with the bottom bracket This is where your water-bottle cage usually goes On older bikes, this was the location for the friction shifters Seat tube: The seat tube is what supports your butt by holding the seat post and saddle in place It s often used for attaching water-bottle cages and bike pumps Bottom-bracket shell: This is a short, fat tube that holds the bottom bracket It runs sideways across the bottom of the bike and is usually threaded There also is a rear triangle, which consists of the seat tube, along with the following: Chain stays: Chain stays run parallel to the bike chain and connect the bottom bracket to the rear dropouts On some bikes, cables are routed along the chain stays Seat stays: The seat stays connect the seat tube with the rear dropouts They re often used for mounting brakes, fenders, or bike racks The final section of the frame is the fork and steerer tube The fork is how the front wheel connects to the bike It consists of two legs with a dropout each for the wheel and a steerer tube, which inserts into the head tube A number of factors in the geometry of a frame affect how the bike handles: Seat-tube angle: The seat-tube angle is based on the angle of the seat tube in relation to the ground This angle determines how your weight is distributed between the saddle and the handlebars A steeper seat tube creates a more aerodynamic position with more of your weight shifted forward to the handlebars With a shallower seat tube, the saddle is positioned farther behind the bottom bracket and your weight is directed toward the back of the bike
