What is the difference between Nexus and Alfine?
The two main differences compared to Alfine 8 seem to be the exterior finish, which is better on the Alfine, and the braking options. Both can use rim brakes, Nexus 8 Premium can use roller brakes, while Alfine can use disc brakes. AFAIK the coaster brake Nexus hubs are/were the “ordinary” version with plain bearings.
Are Alfine gears any good?
Our review
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.
How does Alfine hub work?
Instead, the sealed Alfine employs an oil bath—like a car’s transmission—which can be drained through a port. Fresh oil can be injected with a special syringe. The whole system spins around a stationary axle that has three pawls—spring-loaded, wedge-shaped pieces of metal.
How do you remove a Shimano Alfine wheel?
You need to pull the wheel upwards. Towards you to remove it it should slide out easily. If you have horizontal dropouts you’ll need to pull the wheel backwards.
What is a roller brake on a bike?
A Roller Brake is a modular cable-operated drum brake manufactured by Shimano for use on specially splined front and rear hubs. Unlike a traditional drum brake, the Roller Brake can be easily removed from the hub.
Are hub gears any good?
Hub gears are great as they rarely need maintenance and last for years. Aside from feeding oil into the hub every few thousand km, not much can go wrong with them as they are protected from the rain, snow, salt etc – all the things that cause rust and wear on exposed gears.
Does Sturmey Archer still exist?
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.
How long do hub gears last?
People routinely get over 100,000 km out of Rohloff Speedhubs. I have heard of Sturmey Archer hubs from the 50s still in use. Even lower cost Shimano Nexus or Alfine hubs can go 15,000 km before they need to be replaced. For the average cyclist, a quality internal gear hub lasts a lifetime if properly maintained.
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.

Do roller brakes wear out?

Which is better disc or drum brakes in bicycles?
Drum brakes require less frequent maintenance than disc brakes. A drum brake has no external rotor which risks getting warped or bent, and whose sharp edges can cause injury in a crash. A front drum brake does not tend to pull the wheel out of the fork. Drum brakes are generally easier to modulate than disc brakes.
Are Sturmey-Archer hubs reliable?
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.
Is Sturmey-Archer good?
In any case, the quality of Taiwanese production from SunRace/Sturmey-Archer so far has been excellent, generally better than the quality of later English production. Sturmey-Archer’s selection of multi-speed hubs is much wider than that of the other manufacturers.
Which is best hub or derailleur?
Derailleurs are more efficient- In optimal conditions, derailleurs have slightly greater mechanical efficiency than internal gear hubs. Depending on the models and conditions, derailleurs are about 2-10% more efficient. This is because the system uses fewer gears to transfer energy from the pedals to the rear wheel.
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.

Do pro cyclists use disc brakes?
Disc brakes are still far from dominating the peloton, but there are an awful lot of disc-equipped bikes. We roamed the team trucks ahead of the Grand Depart in Brussels last week to get a closer look. Six teams have completely switched over to disc brakes for the Tour.
Which bike braking system is best?
Disc brakes are one of the most powerful bike brake types on the marketplace. Although invented after the rim brake, they are arguably the most well-regarded brakes in cycling, due to their increased responsiveness and consistent performance in all weather conditions.
