Question: Cycling gear ratios?

What is the best gear ratio for cycling?

High Gear Ratios

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 gear ratios 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.

What gear should you cycle in?

Low Gear = Easy = Good for Climbing: The “low” gear on your bike is the smallest chain ring in the front and the largest cog on your cassette (rear gears). In this position, the pedaling will be the easiest and you’ll be able to pedal uphill with the smallest amount of resistance.

What cassette ratio do I need?

The vast majority of road bikes come with a 12-25 cassette, which is suitable for most cycling terrain when paired with a compact or standard chainset. If you ride a lot of hills or struggle with hill climbing, a cassette with a lower ratio largest sprocket (27 or more teeth) may be beneficial.

What is the easiest gear on a bike?

The easiest (lowest) gear is when the chain is on the smallest ring in the front and the largest cog in the rear. The rest of the gears range between those two extremes. The bigger chainring is HARDER to pedal and the smaller chainring is EASIER to pedal. The ring(s) in the front are individually called chain rings.

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.

What is an 11 32 cassette?

The rear cassette is 11 speed 1132. This means there are 11 cogs ranging from 11 teeth up to 32 teeth (the exact cogs are 11/12/13/14/16/18/20/22/25/28/32). The combination of your selected chainring and cog determine the gear ratio.

What gear combination is best for going uphill?

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.

How do bike gear ratios compare?

The best way to compare chainring and cassette combinations between bikes is to check their gear inches. They’re very easy to calculate: it’s the diameter of the wheel, times the size of the front chainring, divided by the size of the rear cog.

What gear should I bike in on flat road?

Top tips for finding the right gear when cycling

On flat or rolling terrain on your own or in a group, you should be looking to have a cadence of between 80-90 revolutions of the pedal per minute.

What is the best gear set for road bikes?

Performance Shimano groupsets: 105 and Ultegra

Shimano 105 is the most affordable performance-focused groupset from the Japanese firm, and comes on many mid-market road bikes. This 11-speed group is considered by many riders to be the best combination of performance, durability and value.

How do you control cycle gears?

Some important tips to remember when using a geared cycle:

  1. Don’t shift too quickly:
  2. Left= big changes, right= fine tuning.
  3. Anticipate the climb:
  4. Don’t cross-chain:
  5. Practice makes perfect: Get comfortable and understand how each combination of cogs and chainrings work.

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.

Can a 52 34 chainring run?

Officially it’s not supported but a few club mates run 52/34 on Dura ace/ultegra and report it’s fine. I did La Marmotte last year. I ran a 50/34 with a 11-34 cassette.

How do I choose a gear ratio?

The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
