A special note for parents: As a parent or guardian, you are responsible for the activities and safety of your minor child, and that includes making sure that the bicycle is properly fitted to the child; that it is in good repair and safe operating condition; that you and your child have learned and understand the safe operation of the bicycle; and that you and your child have learned, understand and obey not only the applicable local motor vehicle, bicycle and traffic laws, but also the common sense rules
C. Mechanical Safety Check Routinely check the condition of your bicycle before every ride. • Nuts, bolts screws & other fasteners: Because manufacturers use a wide variety of fastener sizes and shapes made in a variety of materials, often differing by model and component, the correct tightening force or torque cannot be generalized.
D. First ride 2. Safety When you buckle on your helmet and go for your first familiarization ride on your new bicycle, be sure to pick a controlled environment, away from cars, other cyclists, obstacles or other hazards. Ride to become familiar with the controls, features and performance of your new bike. A. The Basics Familiarize yourself with the braking action of the bike (see Section 4.C).
B. Riding Safety 1. 2. 3. 4. Obey all Rules of the Road and all local traffic laws. You are sharing the road or the path with others — motorists, pedestrians and other cyclists. Respect their rights. Ride defensively. Always assume that others do not see you. Look ahead, and be ready to avoid: • Vehicles slowing or turning, entering the road or your lane ahead of you, or coming up behind you. • Parked car doors opening. • Pedestrians stepping out. • Children or pets playing near the road.
E. Night Riding Riding a bicycle at night is much more dangerous than riding during the day. A bicyclist is very difficult for motorists and pedestrians to see. Therefore, children should never ride at dawn, at dusk or at night. Adults who chose to accept the greatly increased risk of riding at dawn, at dusk or at night need to take extra care both riding and choosing specialized equipment which helps reduce that risk. Consult your dealer about night riding safety equipment.
F. Extreme, stunt or competition riding Whether you call it Aggro, Hucking, Freeride, North Shore, Downhill, Jumping, Stunt Riding, Racing or something else: if you engage in this sort of extreme, aggressive riding you will get hurt, and you voluntarily assume a greatly increased risk of injury or death. Not all bicycles are designed for these types of riding, and those that are may not be suitable for all types of aggressive riding.
clearance of two inches (5 cm). A bike that you’ll ride on unpaved surfaces should give you a minimum of three inches (7.5 cm) of standover height clearance. And a bike that you’ll use off road should give you four inches (10 cm) or more of clearance. 2. Step-through frame bicycles Standover height does not apply to bicycles with step-through frames. Instead, the limiting dimension is determined by saddle height range.
Always tighten fasteners to the correct torque. Bolts that are too tight can stretch and deform. Bolts that are too loose can move and fatigue. Either mistake can lead to a sudden failure of the bolt, causing you to lose control and fall. Note: If your bicycle is equipped with a suspension seat post, the suspension mechanism may require periodic service or maintenance. Ask your dealer for recommended service intervals for your suspension seat post.
WARNING: An insufficiently tightened stem clamp bolt, handlebar clamp bolt or bar end extension clamping bolt may compromise steering action, which could cause you to lose control and fall. Place the front wheel of the bicycle between your legs and attempt to twist the handlebar/stem assembly. If you can twist the stem in relation to the front wheel, turn the handlebars in relation to the stem, or turn the bar end extensions in relation to the handlebar, the bolts are insufficiently tightened. D.
• A hollow axle with a shaft (“skewer”) running through it which has a nut on one end and a fitting for a hex key, lock lever or other tightening device on the other (through bolt, fig. 9) Your bicycle may be equipped with a different securing method for the front wheel than for the rear wheel. Discuss the wheel securing method for your bicycle with your dealer.
2. Wheels with cam action systems There are currently two types of over-center cam wheel retention mechanisms: the traditional over-center cam (fig. 8a) and the cam-and-cup system (fig. 8b). Both use an over-center cam action to clamp the bike’s wheel in place. Your bicycle may have a cam-and-cup front wheel retention system and a traditional rear wheel cam action system. a. Adjusting the traditional cam action mechanism (fig.
NOTE: If, on a traditional cam action system, the lever cannot be pushed all the way to a position parallel to the fork blade, return the lever to the OPEN position. Then turn the tension adjusting nut counterclockwise one-quarter turn and try tightening the lever again. D (6) With a through-bolt or bolt-on system, tighten the fasteners to the torque specifications in Appendix D or the hub manufacturer’s instructions. d.
B. Seat post cam action clamp Some bikes are equipped with a cam action seat post binder. The seat post cam action binder works exactly like the traditional wheel cam action fastener (Section 4.A.2) While a cam action binder looks like a long bolt with a lever on one end and a nut on the other, the binder uses an over-center cam action to firmly clamp the seat post (see fig. 8a).
1. Brake controls and features It’s very important to your safety that you learn and remember which brake lever controls which brake on your bike. Traditionally, the right brake lever controls the rear brake and the left brake lever controls the front brake; but, to make sure your bike’s brakes are set up this way, squeeze one brake lever and look to see which brake, front or rear, engages. Now do the same with the other brake lever.
D. Shifting gears Your multi-speed bicycle will have a derailleur drivetrain (see 1. below), an internal gear hub drivetrain (see 2. below) or, in some special cases, a combination of the two. 1. How a derailleur drivetrain works If your bicycle has a derailleur drivetrain, the gear-changing mechanism will have: • a rear cassette or freewheel sprocket cluster • a rear derailleur • usually a front derailleur • one or two shifters • one, two or three front sprockets called chainrings • a drive chain a.
e. What if it won’t shift gears? If moving the shift control one click repeatedly fails to result in a smooth shift to the next gear chances are that the mechanism is out of adjustment. Take the bike to your dealer to have it adjusted. 2.
Many clipless pedals are designed to allow the rider to adjust the amount of force needed to engage or disengage the foot. Follow the pedal manufacturer’s instructions, or ask your dealer to show you how to make this adjustment. Use the easiest setting until engaging and disengaging becomes a reflex action, but always make sure that there is sufficient tension to prevent unintended release of your foot from the pedal.
G. Tires and Tubes 1. Tires Bicycle tires are available in many designs and specifications, ranging from general-purpose designs to tires designed to perform best under very specific weather or terrain conditions. If, once you’ve gained experience with your new bike, you feel that a different tire might better suit your riding needs, your dealer can help you select the most appropriate design.
5. Service WARNING: Technological advances have made bicycles and bicycle components more complex, and the pace of innovation is increasing. It is impossible for this manual to provide all the information required to properly repair and/or maintain your bicycle. In order to help minimize the chances of an accident and possible injury, it is critical that you have any repair or maintenance which is not specifically described in this manual performed by your dealer.
WARNING: Like any mechanical device, a bicycle and its components are subject to wear and stress. Different materials and mechanisms wear or fatigue from stress at different rates and have different life cycles. If a component’s life cycle is exceeded, the component can suddenly and catastrophically fail, causing serious injury or death to the rider.
Industry usage conditions are generalized and evolving. Consult your dealer about how you intend to use your bike. High-Performance Road CONDITION 1 Bikes designed for riding on a paved surface where the tires do not lose ground contact. INTENDED To be ridden on paved roads only. NOT INTENDED For off-road, cyclocross, or touring with racks or panniers. TRADE OFF Material use is optimized to deliver both light weight and specific performance.
is relatively short since the bike is intended to move quickly on the ground. NOT INTENDED For Hardcore Freeriding, Extreme Downhill, Dirt Jumping, Slopestyle, or very aggressive or extreme riding. No spending time in the air landing hard and hammering through obstacles. TRADE OFF Cross-Country bikes are lighter, faster to ride uphill, and more nimble than All-Mountain bikes. Cross-Country and Marathon bikes trade off some ruggedness for pedaling efficiency and uphill speed.
The terrain and type of riding that Freeride bikes are designed for is inherently dangerous. Appropriate equipment, such as a Freeride bike, does not change this reality. In this kind of riding, bad judgment, bad luck, or riding beyond your capabilities can easily result in an accident, where you could be seriously injured, paralyzed or killed. NOT INTENDED To be an excuse to try anything. Read Section 2. F, p. 10.
Road Tandems CONDITION 1 Bikes designed for riding on a paved surface where the tires do not lose ground contact. INTENDED Are designed to be ridden on paved roads only. They are not designed for mountain biking or off-road use. NOT INTENDED Road tandem should not be taken off-road or used as a mountain tandem. MAXIMUM WEIGHT LIMIT RIDER LUGGAGE TOTAL lbs / kg lbs / kg lbs / kg 500 / 227 75 / 34 575 / 261 Appendix B The lifespan of your bike and its components 1.
Periodic, more detailed inspection of your bicycle is important. How often this more detailed inspection is needed depends upon you. You, the rider/owner, have control and knowledge of how often you use your bike, how hard you use it and where you use it. Because your dealer cannot track your use, you must take responsibility for periodically bringing your bike to your dealer for inspection and service.
One can design a part that is so strong that fatigue life is nearly infinite. This requires a lot of material and a lot of weight. Any structure that must be light and strong will have a finite fatigue life. Aircraft, race cars, motorcycles all have parts with finite fatigue lives. If you wanted a bicycle with an infinite fatigue life, it would weigh far more than any bicycle sold today. So we all make a tradeoff: the wonderful, lightweight performance we want requires that we inspect the structure.
B. Understanding composites All riders must understand a fundamental reality of composites. Composite materials constructed of carbon fibers are strong and light, but when crashed or overloaded, carbon fibers do not bend, they break. What Are Composites? The term “composites” refers to the fact that a part or parts are made up of different components or materials. You’ve heard the term “carbon fiber bike.” This really means “composite bike.
C. Understanding components It is often necessary to remove and disassemble components in order to properly and carefully inspect them. This is a job for a professional bicycle mechanic with the special tools, skills and experience to inspect and service today’s high-tech high-performance bicycles and their components. Aftermarket “Super Light” components Think carefully about your rider profile as outlined above.
Appendix D Fastener Torque Specifications Correct tightening torque of threaded fasteners is very important to your safety. Always tighten fasteners to the correct torque. In case of a conflict between the instructions in this manual and information provided by a component manufacturer, consult with your dealer or the manufacturer’s customer service representative for clarification. Bolts that are too tight can stretch and deform. Bolts that are too loose can move and fatigue.
