Are hub gears any good?
Hub gears aren’t as efficient as well-maintained derailleur gears. All those pinions whirring around create friction. A simple 3-speed hub is comparable in efficiency to a 27-speed derailleur set-up.
What does it mean when your gears are hard to shift?
Difficulty in shifting can indicate that it is time to change the fluid. Transmission fluid should be flushed and replace roughly every 100,000 miles. Failing Transmission: Over time, especially as a vehicle goes over the 100,000 mile mark, parts and gears inside the transmission simply wear out.
Why won’t my front derailleur shift up?
Front derailleurs may cause sluggish or inaccurate shifting because (A) the derailleur body is not positioned properly, (B) the derailleur limit screws are not adjusted correctly, (C) the mechanism is dirty or (D) the cable is damaged or improperly tensioned.
How long do hub gears last?
They often last many years without any maintenance. These basic hubs may last 50,000 Km without any service. What is this? Higher-end oil-based internal gear hubs like the Rohloff and Shimano Alfine require regular oil changes to keep them running smoothly.
Are internal gear hubs better?
With an internally geared hub you can 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 do you clean hub gears?
Clean the inside of the hub shell. Apply grease to the bearings and clutch rollers. I also inject 3cc or 4cc of the special Shimano oil (ice cream topping) between the gears before putting everything back together. Reinsert the cartridge and wipe off the excess grease.
What is hub gear system?
A hub gear is a gear ratio changing system which is used on bikes. Hub gears are relatively low maintenance as all the moving parts are sealed within the unit. What are the advantages of hub gears? Generally, hub gears have a long-life span and are usually maintenance free.
What causes an automatic transmission to shift hard?
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
What are the possible causes of hard gear?
