At a cadence of 90 rpm (which is very comfortable and most people can handle significantly more), a 50-tooth chainring and a 12-tooth cog gives a speed of 47 km/h. That’s a gear ratio of 4.17:1, so a highest gear ratio of around 4:1 should be sufficient for ultra-distance cycling.
What is the best gearing for a road bike?
Most new endurance and entry level road bikes are specced with 50/34 chainsets, racing bikes with 52/36, and time trial bikes with 53/39. This is good news for most riders as the gearing corresponds to the type of riding for which the bike is intended.
Which gear ratio is best for high speed?
Gear ratios on most brands of baitcast reels range from 5.0:1 to 9.1:1. The pros use high speed models (7.1:1 to 9.1:1) for most applications because they know it is easier to slow down a retrieve with a fast reel than it is to crank faster with a low-speed model.
Is it better to have a higher or lower gear ratio?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential.
What gear should you cycle in?
When riding uphill or into a headwind, it’s best to use the small or middle front chainring and bigger rear cogs. When riding downhill, it’s best to use the bigger front chainring and a range of the smaller rear cogs.
Is gear 1 high or low on a bike?
Bikes generally have 1, 3, 18, 21, 24, or 27 speeds. (10- and 15-speeds are obsolete and you don’t see them on new bikes anymore.) Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear.
How do I choose a gear ratio?
To find the ideal selection, multiply the final drive ratio by the redline speed in fourth gear (152 mph) and divide that by the top track speed (140 mph). This would yield a theoretical 3.33—which is close enough to the nearest available final drive ratio of 3.36:1.
Are 3.73 or 4.10 gears better?
A 3.73 is a higher gear ratio for half ton pickups its not the best gear for pulling trailers, now the 4.10 gears come stock from the factory on newer trucks and is one of the best rear end gears to use if you plan on pulling a trailer. These both vary by fuel mileage consumption so choose wisely.
Are 3.73 gears good for highway?
Well, if you plan on doing a lot of freeway driving, you don’t want to choose a gear that’s too low for your car because you’ll be going down the freeway at too high of an RPM. … Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc.
Is 3.42 or 3.73 better?
The difference in towing mpg between the 3.42 and 3.73 gears at highway cruise speed, under the same conditions, should be less than 1 mpg because of the slightly higher rpm running 3.73s. Vehicle speed actually plays a bigger role in fuel economy than engine rpm.
Does gear ratio affect horsepower?
Motor HP does not change when you change gear ratios. The only thing that changes is torque. A dynamometer measures torque and RPM, and from those two values calculates horsepower. When you change gear ratios both RPM and torque will change but horsepower will not.
Is 3.55 or 3.73 gears better?
3.55 will give you a little better gas mileage on the highway and slightly more highway oriented performance. 3.73 may be better for towing, lower end power (off the line acceleration), and may result in worse gas mileage on the highway.
Are 4.11 gears good?
4.11:1 is a “lower” gear ratio, meaning you have more torque, lower top speed, and you will generally consume more fuel. Usually people put 4.11:1 gears in trucks to be used off-road for the extra torque and the better “crawling” capabilities.
What gear should I use going uphill?
Ideally, you should approach the incline in fourth or fifth gear, while accelerating the car at about 80 percent power. Warning: Use caution when climbing a hill and ensure that you do not gather too much speed.

How many gears should a road bike have?
A road bike will have either a triple, double or compact crankset. This refers to the number and size of chainrings (located by the pedals). A triple crankset has 3 chainrings; it is often paired with a 9-speed cassette on the rear wheel to give it a total of 27 gears.
