If what you're after is getting the maximum possible speed/distance for the minimum effort (and there's nothing wrong with that!) you need a multi- speed bike.. If you're riding for sheer pleasure, or for exercise, you don't necessarily place that high a premium on output results, as measured in speed, distance or vertical climb. Instead, you may care more about the actual experience of riding your bike. In this case, you may be a candidate for a singlespeed bike. Riding a singlespeed can help bring back the unfettered joy you experienced riding your bike as a child.

You don't realize how much mental energy you devote to shifting until you relinquish your derailers, and discover that a whole corner of your brain that was formerly wondering when to shift is now free to enjoy your surroundings and sensations. Paradoxically, a singlespeed is, in another sense, more efficient than a multispeed bike! While the single gear ratio will not be the .

There's no derailer to bash if the bike falls over, catch on the underbrush or get overshifted into the spokes. The rear wheel itself is a lot stronger than one made with off- center (dished) spoking to make room for a whole bunch of sprockets on one side. The one- speed revolution actually involves two different styles of bikes, singlespeeds and fixed gears. These are not the same thing, although they have much in common. A fixed gear bike differs in that it does not permit coasting: when the bike is rolling, the pedals will turn, just as with a child's tricycle. To enjoy the one- speed experience to the max, a fixed gear is the best choice if you ride mostly on pavement.

A fixed gear gives a degree of control and one- ness with the bike that is not equaled by a freewheeling bike. This site also contains several articles dealing with fixed- gear bikes. Fixed gear is not ideal for all circumstances, however.

A fixed gear is not well suited for seriously hilly terrain, and, more importantly, is not good for technical mountain biking. A mountain biker in difficult terrain must be able to control when each pedal is down, to avoid striking a pedal on rocks, logs or other obstructions. Similarly, jumping over obstacles is much more difficult on a fixed gear. If your single gear is low enough for off- road climbing, it will be too low to spin on the descents.

You don't have to choose once and for all between fixed and freewheel, because the same bike can be both, if you use a reversible . If it turns out to be a problem, you can easily convert to freewheel later if you want to.. Most folks who set up their bikes with a fixed/free flip- flop wind up using the fixed gear side pretty much all of the time. The freewheel option is mainly useful for when you have taken a longer- than- usual ride, and need to get home even though you're all tuckered out.

Freewheel vs Coaster Brake. While coaster (backpedaling) brake bikes are also, mostly, single- speed machines, I don't recommend them for technical off- road use. Coaster- brake hubs have a good deal of internal friction, and coaster brakes have a number of serious drawbacks: You can only apply the brake forcefully in two crank positions. If your foot slips off the pedal, you can't brake at all. If your chain breaks or falls off, the brake fails. Without a hand- operated front brake, you can't stop as short as a bike that does have one. On a long descent, a coaster brake will overheat and burn the grease inside it.

It is very awkward to get started, because you can't rotate your cranks to a good starting position without lifting the rear wheel. Because you usually switch feet before restarting, it is impractical to use toe clips and straps, or clipless pedals. Wheel removal/replacement is more complicated, due to the need to attach the brake arm to the frame, and because you can't get a coaster brake with a quick release. You can't have a flip- flop hub. You can use a flip- flop hub, a multi- speed freewheel hub, a cassette hub, a single- speed BMX hub, or a singlespeed MTB hub. Flip- flop Hubs. Flip- flop, or double- sided, hubs are threaded on both sides. Usually one side has a track- type threading, (with lockring) and the other side is threaded for a single- speed standard freewheel.

The usual way to use a flip- flop hub is to have a fixed gear on one side, and a single- speed freewheel on the other. The freewheel sprocket is larger than the fixed sprocket, providing a lower gear. On an MTB, you use the fixed- gear side for most pavement riding, and save the freewheel for off- road use, or for getting you home when you are tired. Call Od Duty 2 Punkbuster Download. Having the freewheel larger than the fixed sprocket gives you a lower gear when you are using the freewheel.

This makes climbing easier. Since you can coast when you are using the freewheel, the lower gear is no disadvantage on the descents. Single- speed freewheels are commonly used on BMX bicycles: most shops that deal in BMX parts should stock them. The common size used for BMX is 1. Note, there are two types of hubs called . A single BMX freewheel will thread right on.

Unfortunately, the chainline is likely to only work with your granny gear unless you re- space the rear axle and re- dish the wheel. Cassette Hubs. It is easy to convert a Shimanocassette. Freehub . The simplest way is just to remove the derailers, shorten the chain and thread it onto the chainwheel and rear sprocket of your choice.

This is less than ideal, however, because you've got the extra weight of the unused sprockets to deal with, and the chainline will probably be crooked. The sprockets used on multi- speed cassettes are designed for easy shifting, which is not a good thing on a bike that isn't supposed to shift! The better way to convert a cassette.

Freehub . You will also need a bunch of spacer washers to hold the single sprocket in place. You can often get a suitable number of spacers by taking apart a couple of discarded, worn- out cassettes. Having a single sprocket sandwiched in a stack of spacers makes it easy to get the sprocket properly aligned for perfect chainline with whichever chainwheel you choose to use in front. You can use one of the old sprockets from your taken- apart cassette, but it you are less likely to have accidental derailment if you use sprockets made for single- gear us, with longer teeth. BMX cassette sprockets are best. These sprockets are quite inexpensive, and are available in a range of sizes.

Disc Brakes. Disc brakes are increasingly popular for off- road use. They don't depend on good rim true, and don't get contaminated by mud.

A number of high- end ready- made singlespeed bikes are supplied with front and rear disc brakes. In my opinion, this is not a good thing. Personally I consider a rear disc brake a very poor choice for a singlespeed. It would preclude you from using a flip- flop hub.

Also, as the chain wears and the axle is moved backward to take up the slack, the relationship of the disc to the caliper will change. That can't be good. Singlespeeds are generally not practical for terrain so steep as to require dual disc brakes. There's no such problem with a front disc brake, but I strongly advise against getting a rear disc setup for a singlespeed.
