Jan 23, - for a step-by-step guide to removing and replacing a bicycle cassette. from each other, and how to choose the right one to suit your needs.
The ramps for chain pickup on newer sprockets also face to the right.
If installed backwards, these sprockets will shift very poorly. Some older sprockets are symmetrical, so you can extend their life bikke turning them over.
With older freewheels, there were commonly 2 or 3 different thread sizes on the same freewheel, so sprockets made for one position wouldn't necessarily fit on another position. Threaded sprockets also had built-in spacers, so they could only be installed in one direction. Standard spaced 6-speeds required increasing the frame spacing to mm, aggravating the problems introduced with the move to 5-speed, but still hi vis bike jacket satisfactory service in most cases.
As it turned out, the increased length of remvoe axle sticking out from the right side of the hub was just too long for traditional 10 mm threaded axles.
Bike front suspension a result, 8-speed freewheels eventually pretty much disappeared from the market. As the number of sprockets has continued to increase to 9 and beyond, thread-on freewheels have become obsolete for high-end applications.
Do you need to replace an older, threaded rear hub to update to a modern, index-shifting drivetrain? Not unless you insist on having more femove sprockets than you probably need.
It's nice spec hype to advertise 9, 10, 11 speeds at the rear, but you can get a wide range and narrow steps with 6 or 7 sprockets and compact double see example or triple chainwheels. Modern 5-and 6-speed freewheels have a 5. You may need to adjust the cable routing slightly with an 8-speed shifter. Highlands bike park index shifter's extra clicks will be blocked by the limit stop on the derailer. This is a nice, even progression, or you may choose another -- see list of available freewheels from Harris Cyclery.
Modern freewheels have the same easy-shifting features as cassettes. Unless you are willing to put up with friction shifting, you uow to install new shifters.
Indexing handlebar-end shifterstop-mount shifters or downtube shift levers let you know how aa shift by feel. Brake-lever shifters return to the same position after every shift, so you don't know what gear you are using.
They also tend to be expensive. Brazed-on bosses for downtube shifters on some older frames will not fit today's index shift levers or cable stopsso you will need to use a clamp-on adapter. A 5-speed freewheel or Suntour Ultra-6 will work with the in rear dropout spacing that was usual in the s.
A 7-speed freewheel needs at least mm road bike inner tube size, but only steel frames are likely to have narrower spacing, and they can usually be cold set to spread the dropouts. You also may need to redish the rear wheel-- see article on frame spacing. To convert to a cassette, you would have to replace the rear wheel.
To be sure, freewheel choices are somewhat limited, unless you have been hoarding how to remove a cassette on a bike sprockets. Back in the days of 4- 5- even 6-speed freewheels, it used to be common to customize the ratios. When there cassstte so few sprocket positions available, it rsmove more important to provide the specific sizes desired to match a given rider's style and riding conditions.
As gears proliferated through 7- 8- 9- and now speed cassettes, this became less of an issue. As a result, custom gearing is now much less common than formerly.
But with a wide-range triple crankset, this is not much of an issue. On the other hand -- how to remove a cassette on a bike older cyclists assume that it is harder to customize cassette-type clusters than it was with the old thread-on freewheels.
In fact, the blue specialized mountain bike is the case!
Cassettes are much easier to customize, because all of the sprockets use the same spline pattern, so any of the sprockets except the smallest one can be used at any position on the Freehub body. With thread-on freewheels, the body is "stepped" so that sprockets for different positions will attach with different spline or thread patterns.
Back in the day, better bike shops would have a big "sprocket board" with dozens of hooks to stock all of the various permutations of tooth count and attachment size needed to create custom freewheels. Generally how to remove a cassette on a bike different manufacturer would require a different sprocket board, because each manufacturer would have its own proprietary design.
Fortunately, only the bearing balls how to remove a cassette on a bike fall out: It is usually possible to screw the lockring back in bike ride outfit and ride home as long as you don't change bike brake cable. Some freewheels also have one more internal shim than needed, making them rock noticeably as you ride.
So, you may need to service a freewheel, if you want to keep it. The freewheel is the least important bearing on a bicycle, since it only turns when it is not carrying any load.
Some people will ignore my advice and try to service freewheels or have no choiceso here's how to do it.
Leave the freewheel in place on the wheel, or screw it onto a wheel, so that you will have something to hold it with. Breaking the freewheel loose from the wheel now with a freewheel remover reduces the likelihood of damage to the inner body cassetfe.
You should see a ring with two holes in it for a pin spanner to fit into. This is usually the ring which has the brand name of the freewheel marked, and may also have an arrow pointing clockwise, and the word "remove" in one language or another. If you don't see eemove a ring, you may need to remove the smallest sprocket to gain access to it.
This is common buke freewheels with 13 tooth or smaller sprockets. Understanding the fundamentals of how gears work, and what effect varying the size of the front chainrings and rear cassette sprockets will have on your pedalling will help you choose the most suitable gearing for your ability. Likewise a double chainring paired with an speed cassette is buy fatbike speed set-up, and so on. Why have gears at all?
Well, in a nutshell, gears are there to enable us to maintain a comfortable pedalling speed or cadence regardless of the gradient or terrain — something that no one single cassdtte is capable of. Vice versa, combining the smallest front chainring size with the largest rear sprocket size results in the lowest available gear, which will help you keep the pedals spinning when the road points steeply up.
Sharethrough Mobile. A bike with 30 or more gears is not an indication of a machine designed to break the land speed record any more than a bike with only a single gear, assuming similar ratios.
Just like a car, bicycles benefit from a low gear to accelerate from a standstill, or to climb a steep hill, and at the other end of the remmove a high gear helps you cqssette achieve high speeds without over-revving. Continuing with the car example, using too low a gear at high speed would result in high fuel consumption. The same is true of your body pedalling a bike. So, quite simply, more gears means more scope to find your preferred pedalling speed.
They feature a 50T final drive which eclipses most rear brake rotors and can climb stuff that'd have Spiderman ob. Chain, derailleur, shifter and cassette will all need to match.
That said, some companies offer range expander rings which basically means that you lose the smallest gear from the outside of the cassette and replace it with a whopper on the inside. But dual front ring drivetrains are still available? Yes, and they are still very good and an extremely efficient way to offer smooth pedaling. They can be programmed to automatically philippines bikes front rings independently omaha bike trails map that you only need to run one shifter on the bars.
Well, yes, yes they are but the performance is sensational and the sound of a servo automatically selecting how to remove a cassette on a bike next ratio is so much posher than the ham-fisted crunch of chain suck. Take heart though, Shimano have long stood by their policy of trickle-down tech through their product ranges and Di2 has already made it to XT level.

So, I've been cycling around the world for the past how to remove a cassette on a bike years overexaggeration, I stop places and live for a while and I just landed in China and found the frame bent to a perpendicular angle. Anyway, the derailleur is bent and ruined and I'm in a location where there are no bike repair shops or supplies to make the fix. What I'm thinking is to remove a few links from my chain and choose one of the sprockets on the cassette to make it a fixed gear.
I'll be testing this in a couple days, but I'd love to hear what you guys think, maybe a few words of warning, or encouragement that this is actually possible or has been done before. Professor C's E-repair and Upgrade Service.
