Users who are not professionally trained for bicycle assembly should not attempt to install the components themselves using the dealer's manuals. If any part of the information on the manual is unclear to you, do not proceed with the installation. Instead, contact your place of purchase or a local bicycle dealer for their assistance. • Make sure to read all instruction manuals included with the product. • Do not disassemble or modify the product other than as stated in the information contained in this dealer's manual. • All dealer's manuals and instruction manuals can be viewed on-line on our website (http://si.shimano.com). • Please observe the appropriate rules and regulations of the country, state or region in which you conduct your business as a dealer. For safety, be sure to read this dealer's manual thoroughly before use, and follow it for correct use. The following instructions must be observed at all times in order to prevent personal injury and physical damage to equipment and surroundings. The instructions are classified according to the degree of danger or damage which may occur if the product is used incorrectly. DANGER Failure to follow the instructions will result in death or serious injury. WARNING Failure to follow the instructions could result in death or serious injury. CAUTION Failure to follow the instructions could cause personal injury or physical damage to equipment and surroundings. 4 TO ENSURE SAFETY WARNING • When installing components, be sure to follow the instructions that are given in the instruction manuals. It is recommended that you use only genuine Shimano parts. If parts such as bolts and nuts become loose or damaged, the bicycle may suddenly fall over, which may cause serious injury. In addition, if adjustments are not carried out correctly, problems may occur, and the bicycle may suddenly fall over, which may cause serious injury. • Be sure to wear safety glasses or goggles to protect your eyes while performing maintenance tasks such as replacing parts. • After reading the dealer's manual thoroughly, keep it in a safe place for later reference. Be sure to also inform users of the following: • It is important to completely understand the operation of your bicycle's brake system. Improper use of your bicycle's brake system may result in a loss of control or a fall, which could lead to severe injury. Because each bicycle may handle differently, be sure to learn the proper braking technique (including brake lever pressure and bicycle control characteristics) and operation of your bicycle. This can be done by consulting your professional bicycle dealer and the bicycle's owners manual, and by practicing your riding and braking technique. • The brake levers are equipped with a mode switching mechanism to make them compatible with cantilever brakes and roller brakes or V-BRAKE brakes with power modulator. If the incorrect mode is selected it may cause either excessive or insufficient braking force to occur, which could result in dangerous accidents. Be sure to select the mode in accordance with the instructions given in the table below. Mode position Applicable brake C/R position C : Mode position for compatibility with V V • Cantilever brakes cantilever brakes C R R : Mode position for compatibility with roller C R • Roller brakes brakes V position V V V : Mode position for compatibility with C R • V-BRAKE brakes with power V-BRAKE brakes with power modulator C R modulator Use the brake levers with mode switching mechanism in the combinations given above. • Check that the wheels are fastened securely before riding the bicycle. If the wheels are loose in any way, they may come off the bicycle and serious injury may result. 5 For Installation to the Bicycle, and Maintenance: • When securing the brake arm to the frame, be sure to use a brake arm clip that matches the size of the chainstay, and securely tighten them with the clip screw and clip nut to the specified tightening torque. Use a lock nut with a nylon insert (self-locking nut) for the clip nut. It is recommended that standard Shimano parts be used for the clip screw, clip nut and brake arm clip. If the clip nut comes off the brake arm, or if the clip screw or brake arm clip becomes damaged, the brake arm may rotate on the chainstay and cause the handlebars to jerk suddenly, or the bicycle wheel may lock and the bicycle may fall over, causing serious injury. • When installing the hub to the frame, be sure to install the correct non-turn washers to the left and right sides, and securely tighten the hub nuts to the specified torques. If the non-turn washers are installed to one side only, or if the hub nuts are not tightened sufficiently, the non-turn washer may fall out, which could cause the hub axle to rotate and the cassette joint to turn. This may then cause the handlebars to be accidentally pulled by the shifting cable, and an extremely serious accident could result. < Coaster brake hub > • When using a fork end with a rear-facing dropout, use the chain adjusters to remove excess slack from the chain. CAUTION Be sure to also inform users of the following: • Be sure to shift the shifting lever one gear at a time. During shifting, reduce the force being applied to the pedals. If you try to force operation of the shifting lever or perform multi-shifting while the pedals are being turned strongly, your feet may come off the pedals and the bicycle may topple over, which could result in serious injury. Operating the shifting lever to multi-shift to a light gear may also cause the outer casing to spring out of the shifting lever. This does not affect the capabilities of the shifting lever because the outer casing returns to the original position after shifting. • If the brake is used frequently, the area around the brake may become

  • In Hub Gearbox Front Wheel Drive Cycles
    In Hub Gearbox Front Wheel Drive Cycles Stephen Nurse 10 Abbott Grove, Clifton Hill, Vic 3068 Email for correspondence: [email protected] Abstract In 1999, Bike Culture Quarterly magazine and Thomas Kretschmer introduced the concept of a chainless bicycle featuring a wide range, front wheel drive gearbox hub. Twenty years later, the European company Kervelo are making production versions of these chainless gearbox cycles (Fig.1). This paper dis- cusses how Kervelos were developed by meeting needs and through dedica- ted individuals and companies. It considers effective uses for human power based on front wheel drive chainless gearbox technology. Figure 1: Thomas Kretschmer in 1999, Kervelo Cycle 2018 (Kretschmer, Kervelo) 1. Introduction Change is taking place in human- and low-powered transport, especially cargo- and e-bikes. More bike styles are becoming accepted for more uses as we realize exercise and low carbon economies are essential (Cox 2015). Change in the way we do things is sociotechnical change. It depends on emerging socio-technical frames and the ingenuity and emotional commit- ment of individuals who consider readily available, established products inadequate (Bijker 1995, p. 4, Nurse 2016). This paper discusses a cycle style currently gaining acceptance and looks forward to newer designs. 2. Background Direct front wheel drive cycles date back to Pierre Michaux’s wooden bone- shaker of 1865 (Bijker 1995, p. 27), and variations with speed-increasing gearboxes have existed since the 1891 Crypto Bantam. The Bantam was a form of safety cycle (Sharp 2003, p. 158), invented to make the liberating technology of the high wheel penny farthing less challenging and accessible to more people (Fig.2).

List of bicycle parts by alphabetic order: Axle: as in the generic definition, a rod that serves to attach a wheel to a bicycle and provides support for bearings on which the wheel rotates. Also sometimes used to describe suspension components, for example a swing arm pivot axle Bar ends: extensions at the end of straight handlebars to allow for multiple hand positions Bar plugs or end caps: plugs for the ends of handlebars Basket: cargo carrier Bearing: a device that facilitates rotation by reducing friction Bell: an audible device for warning pedestrians and other cyclists Belt-drive: alternative to chain-drive Bicycle brake cable: see Cable Bottle cage: a holder for a water bottle Bottom bracket: The bearing system that the pedals (and cranks) rotate around. Contains a spindle to which the crankset is attached and the bearings themselves. There is a bearing surface on the spindle, and on each of the cups that thread into the frame. The bottom bracket may be overhaulable (an adjustable bottom bracket) or not overhaulable (a cartridge bottom bracket). The bottom bracket fits inside the bottom bracket shell, which is part of the bicycle frame Brake: devices used to stop or slow down a bicycle. Rim brakes and disc brakes are operated by brake levers, which are mounted on the handlebars. Band brake is an alternative to rim brakes but can only be installed at the rear wheel.
