A bicycle chain can be very energy efficient: one study reported efficiencies as high as 98.6%. … A larger sprocket will give a more efficient drive because it moves the point of pressure farther away from the axle, placing less stress on the bearings, thus reducing friction in the inner wheel.
Do bike chains make a difference?
You won’t notice the difference between a 40 dollar chain and a 90 dollar chain. You’ll notice the difference between a 12 dollar chain and a 60 dollar chain. … If you need to remove the chain to clean it (or the rear derailleur, etc) then it’s much easier to do.
How many miles can you get from a bike chain?
Expect between 1,500 and 3,000 miles from a 10-speed chain. It helps to establish what counts as ‘worn out’. A chain is worn enough to affect transmission efficiency when it lengthens by 0.75% but has some life left if extended mileage is the aim, in which case it should ideally be replaced when it lengthens by 1%.
Are expensive bike chains worth it?
No. The only advantage of expensive chains within a specific brand is the minor reduction in weight. … (i.e. if you like how SRAM chains work on your bike, buy the cheapest SRAM chain. ) 300/400 miles is a very short life span for a chain.
Which is more efficient belt or chain?
More efficient. At their best, chain drives transmit almost 99% of the power that goes into the pedals to the rear wheel. Belt drives aren’t this good. They’re getting better but the difference can be felt.
How often should I change my bike chain?
To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point.
Can you put a bike chain on the wrong way?
Chain direction matters if the chain is worn. … If you have such a chain, you’ll need to make sure that the inside is inside. You can still reverse its direction though, unless it is also directional, i.e there is a left and a right (the second exception).
How do I know if my bike chain needs replacing?
Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.
What causes bike chain to break?
Chains break for a host of reasons, but most common is wear. For example, if a chain has been ridden for 2500 miles, it will actually stretch out. Correspondingly, a ridden chain will be longer from link to link than a new chain. Because the chain is stretched, the metal fatigues is more susceptible to failure.
Are KMC chains better than Shimano?
Summary. The difference between the Shimano chain and the KMC is marginal; your choice will always come to personal preference. … Despite the inconvenience of adjusting the chain, the Shimano runs a lot smoother and will provide you with long-lasting use.
How do I know what bike chain to buy?
When selecting a chain, the first consideration is the number of rear sprockets. The rear cog sets have been made with 5, 6, 7, 8, 9, 10, 11, or 12 sprockets. As the number of cogs on the rear hub increases, the spacing between cogs tends to be reduced.

What are the disadvantages of belt drive?
Disadvantage of belt drive
- Limited Speed range.
- They are not compact.
- Considerable power loss.
- Short service life compared to other mode power transmission.

What are the advantages of chain drive over belt drive?
Highly efficient, chain drives gives the advantage of more power compared to belts. It can be used for both small and large center distances. Chain drives have low maintenance cost. They give a high transmission efficiency of up to 98 percent.
