How do I choose a set of gears?
Quote from video: Make sure that you remember that you're going to be restricted in most countries to the size of gear that you can use 252. By 14 if you'd like to learn how to change your gears like a pro.
What gear ratio is best for uphill?
You will need even lower gear ratios for steep hills that are 8% or more. The most preferred gear ratios on such tracks are 50/34, 40/34, 36/40, 34/36, 34/32, 34/30, and 32/20. However, remember that using gears with such a low ratio will cause you to pedal more, but it will require less effort.
What gear ratios do Tour de France riders use?
A 53/39t chainset is common, with a smaller 36t inner chainring available for mountain stages. Cassette options include two choices, an 11-29t and 11-32t.
What gear combination is best?
For regular terrain on a flat road, the middle gear is ideal. You can shift to the middle gear if you need strength, but not enough to ride on undulating roads. Combine the middle chainring with a triple rear cog to bike ride smoothly on a flat road. For beginners in biking, it is best to keep the bike in middle gear.
What gear ratio is best for speed?
In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears.

Which gear is best for downhill?
Use lower gears to go downhill
When you start to head back downhill, use your engine and transmission to slow the car down instead of the brakes. Shift to a lower gear before you start heading downhill, as this will help slow down the car without you having to ride the brakes, says the National Park Service.
What gear combination is best for going downhill?
High Gear = Hard = Good for Descending: The “highest” gear on your bike is the largest chain ring in the front and the smallest cog on your cassette (rear gears). In this position, the pedaling will be the hardest and you’ll be able to accelerate while traveling downhill.
Is 11/32 cassette Good for hills?
For hill climbing and mountainous terrain, we recommend a road cassette such as the 11-32T SRAM Red 22 XG1190 11 Speed Cassette (A2), or the 11-34T Shimano Ultegra R8000 11 Speed Cassette.
What gearing do professional cyclists use?
Pros often use a 55×11-tooth high gear for time trials. On flat or rolling stages they might have 53/39T chainrings with an 11-21T cassette. In moderate mountains they switch to a large cog of 23T or 25T. These days, they’ve joined the big-gear revolution like many recreational riders.
What gearing does Chris Froome use?
Gearing consisted of 52/38 chainrings, and an 11-28 cassette, which he turned at an average cadence of 97rpm. Using this information, and some complicated maths, we can estimate that Froome spent most of his time using a 38×21 gear ratio.
What size chainring is best for climbing?
Mountain bike chainrings are available in smaller sizes all the way down to 26t, though I’d recommend most riders try a 30t or 28t first to experience how much easier it is to climb.
What are 4.10 gears good for?
This equates to a greater amount of power transferred to the wheels. Installing 4.10 gears improves the car’s performance on the track but with negligible effects to the highway driving. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing.
Does higher gear ratio mean faster?
Gear ratios can be boiled down to a single statement: Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds and better fuel economy. Higher ratios mean the engine has to run faster to achieve a given speed.

How do you determine gear ratio?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
What gear should I use on a flat road?
High Gear. This one is great for descending, accelerating, or for use when you want to go nice and fast on a flat road. In a high gear, you travel a long way for each turn of the pedal.
How do you choose rear end gears?
Quote from video: You're basically trying to decide. At what rpm is your engine going to be spinning at a specific mile per hour. So you can find mile per hour or find rpm let's click on fine rpm.
