Is Shimano Nexus 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.
Why do gears have hubs?
Hub gears provide a means for shifting gear ratios on drivetrains incompatible with external derailleurs such as belt drives and shaft drives.
Are internally geared hubs better?
You will often find that internal gear hubs with a coaster brake are more robust as they have been designed to withstand more pressure from the force of stopping the wheel from turning. Although it does take some getting used to, an internal gear hub with a coaster brake is perfect for city or cruiser bikes.
How much does a Shimano Alfine hub weigh?
The Shimano Alfine hub basically replaces an 8 speed cassette in a 12-38 tooth configuration, and it can only do this by using a 20 tooth sprocket. A weight of 1.590 grams is not on everyone’s taste, and even if you put together the weight of a cassette, a hub and a rear derailleur you’re still far from reaching these figures.
What is Shimano Alfine 8 speed?
Shimano Alfine 8 Speed is, as its name suggests, an 8 speed integrated rear hub. If you ask yourself what this means, you should know that the classical rear derailleur is no longer needed, the drive train becomes more compact, and maintenance work is almost zero.
Are the Alfine 11 hubs any good?
Every Alfine 11 hub I have serviced so far has been trouble-free. Shift problems were always related to the cable or motor unit. There was an early recall of the cassette joint. There is a date code stamped on the arm. I know the good ones Shimano sent me are stamped JF, KJ, or IK and the only bad ones I have come across are IF.
What is the difference between Alfine 11 and Nexus 8?
In the Alfine 11 hub, all the planet pinions run on roller bearings (as per Alfine 8, premium Nexus 8 and Rohloff hubs), so as to decrease losses. Once again (as in the Nexus 7), Shimano has avoided having a nice efficient direct drive gear 5 (or 6).
