Are hub gears reliable?
The main advantages of hub gears over a 1xN derailleur system are reliability and being able to shift while stationary. Since there’s no derailleur or chain tensioner it’s easier to add a full chaincase which means chains last a lot longer and with mudguards added there are no dirty bits accessible on the bike.
How do internally geared hubs work?
Internal-gear hubs work on the principle of “planetary gearing.” Thus, the wheel turns 3 times for every 4 revolutions of the sprocket, lowering the gear by 25%. Middle Gear has the sprocket still driving the gear ring, but the gear ring drives the hub. Thus, the drive is direct.
What are internal hubs?
A hub gear, internal-gear hub, internally geared hub or just gear hub is a gear ratio changing system commonly used on bicycles that is implemented with planetary or epicyclic gears.
How long do internal gear hubs last?
They often last many years without any maintenance. These basic hubs may last 50,000 Km without any service. Higher-end oil-based internal gear hubs like the Rohloff and Shimano Alfine require regular oil changes to keep them running smoothly.
Are hub gears heavy?
Hub gears tend to be a bit heavier than derailleur gears, and it’s noticeable because all the weight is in one lump. This doesn’t really matter for commuting.
Are internal gear hubs heavy?
Internal gear hubs are heavier- Due to the added gears and complexity, internal gear hubs weigh more than derailleur setups. All of this added weight goes into your wheel which slows down acceleration slightly.
What is internal gear?
Internal Gears are gear teeth generated in the internal diameter of a cylinder while external gears have the gear teeth generated on the outside diameter of the component. An internal gear can also be called a ring gear.
Is Nexus or Alfine better?
The main difference between Nexus and Alfine groups is that Alfine is designed for disc brakes, and Nexus is designed for roller brakes. Disc brakes are better for riding in hilly terrain. So if you’re commuting in San Francisco, get the Alfine hub.
Why use an internal gear hub?
With an internally geared hub you can actually shift gears while stationary! Unlike a traditional derailleur system, you don’t need to be pedaling to change gears. This can be great for riding in stop and go city traffic and can also make it a lot easier to down shift on a steep uphill.
How reliable are internal gear hubs?
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.
Is an internal gear hub right for You?
Internal gear hubs are loved by all due to three key factors: reliability, maintenance, and shifting. Firstly, internally geared hubs are very, very difficult to damage. The entire system is held in a casing, which means it is protected at all times, making it heavily reliable.
