Sturmey-Archer - v - Derailleur gears

Hi

I am posting from England, I think that is the same as the USA - we mostley have derailleur gears.
But I am unsure in what way Sturmey-Archer gears are different. Sturmey-Archer are mostly 3 gears. Are they more for slower pased riding?
Over here most Sturmey-Archer gears are on older bikes for sale on ebay. Maybe the compact nature of Sturmey-Archer makes them better for folders?

i like internal hub gears as they are a lot more compact, imo they last a lot more than derailleur, commonly you can see 3-speeds, but theres a lot of 4 speeds, 6 speed 7 and 8....hassle free if you get a good unit.

cons are if it breaks youll mostlikely need to replace the hub, another would be 8 gears aint that much for some...i personally like 3 and 4 speeds.....but to each its own

I used to own bikes with deraileur gearing only at one time. I purchased a old English 3 speed bike with a Sturmey-Archer AW 3 speed hub. Even though the bike (and the hub) was 40 years old, I never experienced anything major than an simple adjustment. Even today with more modern bikes, I still use 3 speed gearing which is fine for me. I can climb 99% of the hills around here. And the gearing system works great for the smaller wheeled folder that constantly folds up. A derailleur might get beaten up with that type of action.

Here is an example on one of my bikes: http://www.flickr.com/photos/world-o...7594461421431/

Hi

If you take a 6 gear derailleur. Would a Sturmey archer be equivalant to the gears 1-3-6 or 1-2-3?
The comparison sites seem really complicated.

I'm starting to lean that way also.. been riding the Dahon Mu Uno quite a bit .. singlespeed .. coaster brake .. 1 cable (front brake). excellent bike .. especially in and around town... currently the first bike I grab for a quick spin of 10 miles or under .. a very minimalist bike that delivers... As to a Sturmey, I still ride my first purchased bike, a 1962 26" Western Flyer 3spd, coaster brake, roadster (Made in England).. 47 years later, the 3spd Sturmey still works perfectly, with just oiling for maintenance ..

For sure it is not 1-2-3, could be 1-4-8 or more. Quite wide range on the old three speeds.

Thanks, that puts it into simple terms for my simple brain, lol. A hub bike might be a good option, now that I know more about them.

Try one, it is what your legs/knees think about it that counts, your brain should not be bothered with this..

Depending on what you need (hilly area? distance pr day, your fitnes) you should care more about what gears you need, not how many they are. If you ride a three gear bike and do not like it then find out why you do not.

To explain it: I picked up a steptrough bike at the dumpster last sumer. Rode it for some weeks to decide if I liked it. It had a Nexus4 hub. Found I only used two out of four gears. The sprocket on the hub had 18 teeth. I tryed bigger ones and ended up with a 23 teeth sprocket. That gave me a good gear range for my riding in this area. Decided I had too many bikes and gave it to a friend, she like the bike a lot. I do not think she would like the bike if it had the 18 tooth sprocket still on when she got it, and also I think she would not have beenable to tell me why.

If you have many gears on your bike then WHAT gears is not so important, you can always find a gear to use. If few make sure they are the right ones.

you can read up about SA 3-sp internal gear hubs here:
http://sheldonbrown.com/sturmey-archer.html
http://sheldonbrown.com/english-3.html
http://sheldonbrown.com/gears/

by far the most common is the AW model, which has 0.75/1.00/1.33 ratios

As an example of an SA-AW setup:
  • 42t chainring x 18t cog + AW 0.75/1.00/1.33
when you compare this to a derailer equipped bike:
  • 42t chainring x 24t, 18t, 13t cogs
the 1.33 the AW offers is right in between 14t and 13t for a derailer equipped bike in this example. The 42x24t and 42x18t are spot on in terms of gear ratios.
