Which is better Shimano Alfine vs Nexus?
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 Shimano Nexus gears good?
Shimano Nexus gear is really popular due to its high build quality and seamless ability to work whenever you need it. The 7 gears provide a great range, perfect for city rides or more challenging touring adventures.
How do you lubricate a Shimano Nexus?
2 Answers
- Add chain lubricant when the chain squeaks.
- Re-tension the chain as it wears and the chain slack increases.
- Replace the chain and possibly the front and rear sprockets when they are too worn.
- Re-grease the internal gear hub.
How do Alfine gears 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.
Are hub gears good?
Generally, hub gears have a long-life span and are usually maintenance free. The advantage of a hub gear is that you can shift gears when stationary. Hub gears allow you to change the gears from top to bottom whilst motionless, which is useful for urban riders who want to change gears at traffic lights.
Is the Shimano Alfine 11 speed hub filled with oil?
Like the Rohloff Speedhub the Shimano Inter 11 is lubricated with oil, rather than grease that other internal gear hubs use. The oil can be supplied through a dedicated hole in the hub, making the procedure fast and easy without requiring removal of the wheel or disassembly of the hub.
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.
