What is the difference between hub gears and derailleur?
While derailleurs need regular chain care and occasional adjustment, hub gears tend to run and run without any cossetting. Gear shifting goes on inside the hub shell, where small pinions mesh together to rotate the rear wheel at a different speed from the sprocket.
What is an IGH bike?
What is an Internal Gear Hub? The internal gear hub, also called hub gear or abbreviated IGH is a system used to change a bicycle’s gear ratio. It achieves this using planetary or epicyclic gears that are housed and sealed within the rear hub.
How does internal hub gearing work?
An interlocking set of gears, called a planetary system, helps you ride up a hill—or go faster on a flat. Depending on the gear, the driver unit either first spins outer ring gears, or the planetary gears deeper in the hub, rotating around sun gears near the center.
How does Alfine hub work?
Quote from video: So power is transmitted to the ring gear at an increased speed. And the roller clutch drives the hub shell. The ratio between the gear carrier and the ring gear is one input revolution to one point
Are derailleur gears good?
The benefits of multiple derailleur gears are that cycling becomes easier. You can keep pedalling at a comfortable rate whilst the rear wheel rotates faster or slower. This is particularly helpful when it is hilly or windy. Derailleur gears are also lighter and means that the wheels weigh less.
Are 3 speed bikes good?
A 3-speed bike is a great option. It gives you more choices and more flexibility than a single-speed bicycle, but it doesn’t reach anywhere near the many options of seven, 21, or even higher-speed bikes. With a 3-speed bicycle, you can tackle riding uphill, downhill, and flat terrain.
Which is better Shimano Alfine vs Nexus?
The Alfine hub gear is the upgraded counterpart to Shimano’s successful Nexus hub. It’s smoother, has a higher-quality feel and looks to be robust enough to go for years. There’s a certain beauty about internally geared hubs; they might be heavier but the bonus is their easy-to-live-with nature.
Are internally geared hubs better?
Internal-gear hubs are more reliable than derailer systems, and require much less maintenance. The step-up ratios of their top gears make oversize chainrings unnecessary on small-wheel bicycles. Unlike derailers, internal-gear hubs can shift at a stop, very nice in stop-and-go urban traffic.
How much does a Rohloff hub cost?
Rohloff hubs are perfectly quiet from gear 8 through to gear 14. There’s no beating around the bush here – Rohloff hubs are expensive. Expect to pay US $1600 or 1100€ just for the hub and shifter (complete bikes start at 2500€). You’ll need to factor in the cost of a new wheel build too.
Are Sturmey Archer gears still made?

Are Sturmey Archer hubs good?
The classic Sturmey-Archer AW hub is the most reliable gear-shifting mechanism ever made, and rarely needs anything more than a bit of medium-weight oil every so often. 95 percent of shifting problems on 3-speeds are related to the control cable or the shifter.
What is advantage of internal gear?
Reliability. One of the biggest advantages of the internal gear hub is that all the moving parts responsible for shifting are completely contained in a sealed unit – the hub. This means they’re completely protected from water, dirt, road salt and grime.

How do I know what derailleur I need?
If you are replacing an existing derailleur on a bike, simply count the number of cogs on your cassette and you’re good to go. If your drivetrain’s speed is an unknown quantity, you can count the number of steps that your shifter runs through and add ‘one’ to determine the number of gears your drivetrain has.

Most modern bikes are equipped with a derailleur gearing system – stay with me, we’ll get to the terminology – where the chain runs between many different cogs.
Is internal gear hub better?
Although both systems of shifting gears have their advantages, internal gear hubs are becoming all the more preferred, competing with the prevailing derailleur system on several fronts. Shifting: Perhaps the most significant difference of internal gear hubs is its ability to shift stationary.
