For MTB cassettes, Shimano’s XTR cassette has the top 3 cogs made of aluminum and the next few made of titanium . XT has its largest 2 cogs made of aluminum. The balance are all steel SRAM’s X01 and XX1 (highest end two groups) may have only the largest cog made of aluminum, with steel for the rest.
What are bike cogs made of?
Cheaper cassettes are made of steel that is highly durable and hard-wearing but at the same time quite heavy. More expensive high-end cassettes for both MTB’s and road bikes are made of lighter metals such as Titanium and Aluminum ; they do however wear out faster as they are softer metals.
How do bicycle cassettes work?
Rather than just being a collection of cogs, the sprockets in a cassette are designed to work together as a whole, with the individual sprockets positioned precisely relative to one another to ensure the chain will shift smoothly between cogs .
How long does a cassette bike last?
Very Roughly: bike cassette can last between 4000 to 6000 miles , and some can last up to 10,000 miles, an equivalent of 3 to 4 chains, it depends on the quality of the cassette itself, maintenance, and riding conditions.
Is more teeth on a cassette better?
If you ride a lot of hills or struggle with hill climbing, a cassette with a lower ratio largest sprocket (27 or more teeth) may be beneficial . It will allow you to keep spinning for longer, rather than grinding. When selecting a cassette for your road bike, ensure your derailleur can accommodate the largest sprocket.
What does a 12 speed bike mean?
On the back, the 12-speed cassette starts at a 10-tooth cog, and increases by 1-tooth per cog. The overall result is that you can reach a higher resistance at the top-end, and your smallest gear is even easier to push .
Where are SRAM cassettes made?
SRAM produces on average 80 percent of all of its in-house parts inside the factory in a vast machining area. Of the parts that aren’t produced by SRAM, 90 percent are sourced in Taiwan . SRAM also makes many of its own machines for its production.
Will a 12 speed cassette fit a 9 speed hub?
It is a wide ratio cassette that has an alloy spider, lockring, and spacer. It will fit any Shimano or SRAM 8, 9, or 10-speed freehub body , and Shimano Dynasys 11-speed mountain freehub bodies.
What is a bike chainring?
Chainrings are literally a vital cog in the machine that is your bike. They’re the part responsible for transmitting the energy you create by turning the cranks to the rear wheel via the chain .
How many cogs are in a cassette?
Rear Gears (Cassette)
Most bikes built in the last few years have between 8 and 11 cogs in the cassette. The largest cogs are closest to the wheel and the gears are numbered from the inside out. The larger the cog the ‘lower’ the gear and the easier it will be to pedal, but the slower you will go.
What is cassette type hub?
Newer bikes tend to use type hub called a “cassette hub.” The cassette hub uses a “freehub” sytem, which is a type of clutch mounted to the body of the hub . This cylindrical mechanism ratchets counter-clockwise for coasting, and locks clockwise for driving the bike when pedaled.
How does chainring size affect speed?
While the choice of cassette determines the gear range of your drivetrain, you can shift the gearing up and down with the size of the chainring. The smaller the chainring, the easier the lowest gear for climbing; the bigger the chainring, the faster you can go in the highest gear .
Can I fit a 12 speed cassette?
Will the 12 speed DuraAce road cassette fit onto my current wheels? Yes it will . Shimano did a great job of ensuring backwards compatibility.
What is gear 7 on a bike?
On a 7-speed bike, the lower gears make it easier to pedal and the higher gears allow for better movement going downhill . Compared to a 3-speed bike, a 7-speed is preferable for a rider who travels on varying terrain.
How much does it cost to replace a bike cassette?
The cost to replace a cassette or freewheel can range anywhere from $25 to upwards of $300 on high end bikes and chainrings can run anywhere from around $40 to $250 on high end bikes.
How do I know if my cassette needs replacing?
How often should I change my bicycle cassette?

Can I put a different cassette on my bike?
Yes, almost any bike is compatible with bigger cassettes , bike drivetrain is groupset of components that works in perfect harmony, any miss reconfiguring can break the perfect functionality of the system, parts that need to be changed and reconfigured when putting bigger cassette which is long-chain, wide cage ...
Which cassette ratio is best for climbing?
All other things being equal, the 34T sprocket on the 11-34T cassette is going to give you the easiest gear. If your bike is currently fitted with an 11-28T cassette, switching to an 11-34T cassette will make climbing less of a struggle.
How do I know what kind of cassette to buy?
The rule of thumb for choosing the right bike cassette is that the closer the number of “teeth” from the largest and the smallest cogs , the smaller the variation between gears, which ensures a smooth gear change.
How many gears are on a bike?
Bikes generally have 1, 3, 18, 21, 24, or 27 speeds . (10- and 15-speeds are obsolete and you don’t see them on new bikes anymore.) Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear.
What gear should I use on a flat road?
For riding on flat roads, it is recommended to use the middle gear . It is a common choice among bikers as it helps you reduce pressure from your feet onto the pedals.
What is the hardest gear on a bike?
High Gear = Hard = Good for Descending: The “highest” gear on your bike is the largest chain ring in the front and the smallest cog on your cassette (rear gears). In this position, the pedaling will be the hardest and you’ll be able to accelerate while traveling downhill.
Where is Shimano manufactured?
