How does a kick shift hub work?
The hub works via coaster-brake action: You push back with your feet lightly to shift gears (both to upshift and to downshift), and you push back harder to brake.
Are Sturmey-Archer gears 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.
Are Sturmey-Archer gears still made?
‘A’ and ‘F’ family hub gears
Sturmey-Archer’s most widely known product is the AW wide-ratio three-speed hub gear, introduced in 1938 (though patented in 1936) and still in production in a substantially modified form as of 2018.
Is Sturmey-Archer out of business?
Insolvent Sturmey Archer closes – BikeBiz.
How do you lubricate a Sturmey Archer hub?
Lubrication. The ideal rule for lubrication should be ‘a little but often’. Two or three drops of oil every week will maintain the hub in first class running order.
Who invented Sturmey-Archer gears?
John James Henry Sturmey
John James Henry Sturmey (1857–1930), known as Henry Sturmey, is best remembered as the inventor with James Archer of the Sturmey-Archer three-speed hub for bicycles, but he was a technical editor and journalist heavily involved as a pioneer of the cycling and automotive industries.
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.
What is a Dynohub?
A Dynamo hub is a small electric generator that is built into the front hub of a bicycle wheel. As the bike’s wheel rotates, the dynamo in the hub generates electricity. You can use this electricity to power lights or charge small electronic devices like a phone, GPS, camera, or a small lithium-ion battery pack.
What kind of oil does a Sturmey Archer hub take?
While you’re probably perfectly fine using 3-in-1 (I used to use it BITD when I owned a Raleigh Chopper) the recommended lube for the job is “light machine oil“… IIRC 3-in-1 has some additives but as far as I can tell there’s nothing in there that’ll harm a Sturmey-Archer (just corrosion inhibitors and citronella).
How do you shift Sturmey-Archer?
Quote from video: When it's all the way in you're in the highest gear third gear. When it comes out a little bit this pin when the end of this the top of this pin right here this little shoulder here the pin.
What is tenacious oil used for?
Our Tenacious Oil is used for ultimate protection and durability for components that have movement with metal-to-metal contact. Our base oil has been produced for us by the same independent California refinery since 1971.
How do you service a Sturmey Archer 3 speed hub?
Quote from video: I'm going to use one of these little notches or notch on this side notch on this side let me use the punch and the hammer to unscrew this basically turn it counterclockwise.
What is SAE 20 oil?
PSC’s SAE 20w-20 Oil category represents lubricants that have a viscosity grade of SAE (Society of Automotive Engineers) 20w-20. This grading system tells you the thickness of the oil and how it is affected by temperature.
How does a Sturmey Archer 3 speed hub work?
Three speed hubs use a planetary gear system to achieve a gear ratio between the sprocket and the wheel. In this gear system the sun gear is fixed in place while the planet carier is rotated. This causes the planet gears to rotate which in turn causes the ring gear to rotate. The rider selects a speed using a shifter.
How do internal gear hubs 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 do you adjust the gears on a 3 speed bike?
Quote from video: And we're going to go ahead and loosen. This at that point we can take this barrel adjuster and twist counterclockwise. And that'll start to move the indicator.
