|Shimano Dura-Ace series gruppo shot.
Text from page:
The Dura-Ace series of bicycle components is the best to be found anywhere. Produced with extra time and attention to detail the Dura—Ace line surpasses the demands of the most severe cyclist, If only the best is good enough, or if competitive performance is essential then Dura-Ace will become the center of the cyclist’s riding satisfaction.
Each part in the Dura-Ace series is engineered to be light and strong. Shimano’s research teams developed a special “micra” alloy which is precision cold-forged into a final lustrous, jewel-like finish. Those who know quality in bicycle components demand the non-compromising value of Dura-Ace.
|Dura-Ace components: Rear derailleur (Crane, Crane GS), Front derailleur, Shifting levers (Dura-Ace downtube, Bar end controls), Cable parts, and Braze on parts. Also shows the some of the same components in the black finish available at the time.|
|Dura-Ace components: Multiple freewheels (5 and 6 speed with gold finish), Light alloy hubs (low flange and high flange), Front chainwheel (crankset). Inset photo shows the same components in "Black Series".|
|Dura-Ace components: Caliper brake, brake lever, Head parts (Headset), Fork ends, Pump holder, Outer band (top tube cable guides). Also shows same in "Black Series".|
|Dura-Ace 'Series for Track': Front and rear hubs with lock ring (high flange), Sprocket for track hub, Fork ends, Head parts, Front chainwheel (crankset).|
|Shimano 600 Series components: Rear derailleur, Front derailleur, Shifting lever, Caliper brake, Cantilever brake, Brake lever, Cable parts, Braze on parts.|
|Shimano 600 Series components: Light alloy hub (low flange and high flange), Fork ends (horizontal and vertical), Front chainwheel. Crankset is interesting three arm design that was available as a triple and went down to 30 tooth sprocket.|
|Rear derailleur: Positron, Shimano 500, and 500GS. Positron was Shimano's first attempt at "index shifting". It used a double cable; one to push and one to pull the mechanism. Text from page:
Presently, if you ride with a conventional 10-speed derailleur, you probably have noticed the necessity to continually make minute adjustments of the shifting lever to remain in gear. In fact, many new 10-speed riders do not learn how to center their chain over the rear sprocket, and they ride along with the chain skipping and making noise. Now, with the new Shimano POSITRON Rear Derailleur, anyone can make positive, smooth gear changes with complete accuracy. You don’t need to make minor adjustments.
Opposite page discusses "Servo Panta design" Text is below:
Servo Panta Mechanism
With the servo pantograph system, no matter how the teeth are assembled, or even if the front double gear is used, the distance between the sprocket teeth and the guide pulley remains practically the same. The special automatic movement of the guide pulley leads the chain, so lever operation is light and gear changes are smooth. The cable saver is included on the Lark and Eagle models.
A. Front Derailleur Capacity
This represents the range of a front derailleur in terms of the difference in the number of teeth between the largest and the smallest chain rings of the front chainwheel.
Capacity: 14 teeth or less
In this case the difference should be 14 teeth or less. If it is greater than 15, the front derailleur will not function
B. Rear Derailleur Capacity
This expresses the range of a rear derailleur in terms of the difference in number of teeth between the largest and the smallest chain rings of the front chainwheel and the number of teeth of the largest multiple freewheel sprocket (low side).
Capacity: Front chainwheel difference: 14 teeth or less Rear Largest Sprocket: (low side) 28 teeth or less
Should this be the case, the difference in tooth number mentioned above must be 14 teeth or less and the tooth number of the largest multiple freewheel sprocket (low side) 28 or less.
|Shimano rear derailleurs: Titlist, Titlist GS, Tourney, Tourney GS, Eagle, Eagle GS, Eagle SPO, and Eagle GPO.|
|Shimano rear derailleurs: Lark SS, Lark SPO, Sky Lark, and Lark W. Shimano front derailleurs: Shimano 50, Titlist, Thunder Bird, and Thunder Bird GPO.|
|Shimano shifting levers: QB lever, QS lever, QP lever, Almi lever, Super Shifter, Finger Tip, and Uni-Shift.|
|Shimano shifting levers: W-Grip Control lever, Twist Grip control, and Trigger lever (3 speed). Shimano freewheels. Multiple and single. Text from page:
A new wide range of freewheels has just been introduced by Shimano. This rear cluster has a broad range of gears, for example, starting with 14, and going to 17-22-28 and 34 teeth. Available in Regular Type; with Top Protector, with Seal and Alternate Teeth Type. Easily removed from the hub with a special tool. The spline system makes it possible to change the sprockets. Every other tooth in the two ultra-low (big) gears has been removed. This makes it easier to shift up into these low gears because the chain does not “hang up”
|Shimano hubs: Small flange hub with quick release, Small flange hub (nutted), Large flange hub with quick release, Large flange hub (nutted), Large flange hub with wing nut, and steel hub.|
|Shimano caliper brake: "Auto Adjust" Tourney sidepull and Tourney centerpull, regular Tourney sidepull and Tourney centerpull. Brake lever: Popular lever, Tourist lever, Hooded lever, Dual Extension lever (Safety lever). Text from page:
The AUTO ADJUST is designed to execute the automatic compensation of the rim-brake shoe clearances which change as brake shoes are worn or the brake wire is stretched. With the AUTO ADJUST, an optimum gap can always be maintained between the brake lever and the handle bar. As a result, greater riding safety is insured.
|Shimano coaster brake (hubs): Mighty Mite and Coaster brake 'B' type. Shimano hub gears: Three speed hub, Three speed coaster brake cartridge type, and Automatic 2 Speed hub (Auto-2).|
Shimano Disc brake: Disc brake with Auto-Adjust and Hydraulic disc brake. Text from Auto-Adjust brake:
|Shimano small parts: Chain rings, cables, "Special Grease", et al.|
|Shimano outer band (cable clamps) and Shimano special tools.|
