His kind of road bikes are geared, so he has a lot of ratios to choose from. A typical range for a road bike would be 12-25 at the rear and 53-39 at the front, giving a highest ratio of 53/12 and a lowest ratio of 39/25. For a mountainous race he can change to larget sprockets at the rear and smaller chainrings at the front. Something like 50-34 at the front and 12-27 rear.

Does Lance Armstrong use a low gear or high gear?
Both, and several inbetween. The gear is chosen to get the same pedalling effort regardless if the course is uphill, flat or downhill at the moment.Ans 2 - Most pro riders will use all the gears necesary to maintain a good 'spin' speed. (rpm of the crank )
What are the uses of Gears?
,gears are used in a bicycle to paddle less and and to gain more speed It is also used in hills because there are steep slopes and if we put it in gear we have to paddle less. Mukul Thakur shimla

What is lance armstrongs fastest speed?
During flat time trials Lance maintains a cadence of 100-115 rpm. He is using a lower gear than most other cyclists, but is pedaling faster than them. Rather than using leg power and sheer muscle strength (as did all the early competitive cyclists throughout the 1900s up until the time of Miguel "Big Mig" Indurain), Armstrong relies on superior cardio fitness to carry him through the mountains. Nowadays, the only cyclists who mash huge gears are the ones with very muscular legs, Jan Ullrich being a prime example. Lances climbing cadence is different however around 80-85rpm, but up to 100rpm when attacking on a long solo breakaway when the gradient lessens during a climbing attack. One reason why Jan and Lance were so exciting to watch together: they had such different styles-and so lance 'looked' faster than yan or any climbers, though he was only going marginally quicker than them...
Top Gear vs fifth gear who won?

What is the Speed Ratio of a bicycle?
The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.

How tall is Lance Gear?

What type of cycling gear did Lance Armstrong where?
In 1999, Lance Armstrong won the Tour de France for the first time, using a Trek 5200 bicycle. In future races, Armstrong rode other Models of Trek Bikes, notably including the 14.5 pound Trek 5900 SL in 2003, which was banned the following year due to new weight requirements for the Tour de France (the rule required all bicycles taking part in the race to weigh at least 15 pounds - or 6.8 kilograms).
What is the best gear ratio for a bicycle climbing a hill?
It really depends on the incline of the hill, but the first is the number of teeth in the smallest chaining (front gears).The second is the number of teeth on the largest sprocket of the cassette (back gears ).You then divide one by the other to get the gear ratio A gear ratio of 1 means that when you turn the pedals one revolution the wheel will rotate once. A gear ratio of 2 means that for every half turn of the pedals the wheel will rotate once.The lower the gear ratio , the easier it is to climb the hill
When was Lance Gear born?
Lance Gear was born on October 13, 1970, in Detroit, Michigan, USA.
Is a bicycle a wheel in axle or a gear?
A bicycle is both.
How do you calculate a gear ratio on a bicycle?
Bicycle gears are measured in inches. The formula is 27 (Size of wheel.) divide by number of teeth on rear sprocket. Multiplied by the number of teeth on chainwheel. Example 27 divide by 18, times 50, equals 75.0 inch gear.
Why is gear ratio also called velocity ratio?
The gear ratio of a train, also known as its speed ratio, is the ratio of the angular velocity of the input gear to the velocity of the output gear. The gear ratio is very important when it comes to physics.
What does p0731 mean on a Chrysler 300?
Incorrect gear ratio in first gear.Incorrect gear ratio in first gear.
What is the relationship between driven gear and drive gear?
The ratio is the driven gear divided by the driver gear. This determines the gear ratio.
