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...

What is the significance of the bicycle gear ratio in determining the efficiency and performance of a bicycle?
The bicycle gear ratio is important because it determines how easily you can pedal and how fast you can go. A higher gear ratio means you can go faster but it's harder to pedal, while a lower gear ratio makes it easier to pedal but you go slower. Finding the right gear ratio can improve your efficiency and performance when riding a bicycle.
What is the significance of the gear ratio in a fixed gear bicycle?
The gear ratio in a fixed gear bicycle determines how easily the pedals turn in relation to the wheel's rotation. A higher gear ratio means more effort is needed to pedal, but it can lead to faster speeds. Conversely, a lower gear ratio requires less effort but may limit top speed. The gear ratio is important for controlling speed, acceleration, and overall efficiency while riding a fixed gear bicycle.
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 do you calculate the gear ratio on a bicycle?
To calculate the gear ratio on a bicycle, divide the number of teeth on the front chainring by the number of teeth on the rear cog. This will give you the gear ratio, which represents how many times the rear wheel turns for each rotation of the pedals.
What website or location in Austin or Houston is best for buying a single speed or fixed gear bicycle?
buy it from mellow johnny's its lance armstrong's bike shop so you know its gotta be good. what what give it up
What is the gear ratio of a bicycle with a chainring size of 53 teeth and a cassette cog size of 39 teeth?
The gear ratio of a bicycle with a chainring size of 53 teeth and a cassette cog size of 39 teeth is 1.36:1.
What is the significance of the 48/16 gear ratio in a bicycle's drivetrain system?
The 48/16 gear ratio in a bicycle's drivetrain system is significant because it determines how much power is transferred from the rider's pedaling to the wheels. A higher gear ratio like 48/16 provides more speed but requires more effort to pedal, while a lower gear ratio offers easier pedaling but less speed. Riders can choose the gear ratio that best suits their riding conditions and preferences.
What is the optimal gear ratio for a 10-speed bicycle when using a 42 tooth cog?
The optimal gear ratio for a 10-speed bicycle with a 42 tooth cog would depend on various factors such as the terrain and the rider's preference. However, a common recommendation is to use a gear ratio of around 2.5 to 3.0 for efficient pedaling on flat surfaces.
Why does the rear wheel of a bicycle turn faster than the pedals?
because of the gear ratio and the chain
How tall is Lance Gear?
Lance Gear is 5' 11".
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 purpose of the smallest chainring on a bicycle's crankset?
The purpose of the smallest chainring on a bicycle's crankset is to provide the lowest gear ratio, making it easier to pedal uphill or in challenging terrain.
