A fixed gear is not well suited for seriously hilly terrain, and, more importantly, is not good for technical mountain biking. 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. If it doesn't, re-arrange spacers or change the bottom bracket axle as necessary. The simplest way around this is to install a chain-tensioning pulley of some sort.

The best gearing for you depends on a large number of variables, including: There is no magic formula for this, only experimentation will let you determine what gearing suits your needs. Check the fork will fit in the frames headtube. 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. 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. Some of the cogs will be attached to an alloy spider with rivets. I have set up a couple of mountain bikes with flip-flop hubs, so that I get a singlespeed on one side and two different freewheel gears on the other. Grease generously to avoid annoying creaks and ticks during the rainy season and tighten rmly. You can only apply the brake forcefully in two crank positions. Incorrect or missing product information? On a long descent, a coaster brake will overheat and burn the grease inside it. 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. The same drive ratio may be achived with a larger or smaller chainwheel and rear sprocket, as long as the proportion is the same. 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. Sign in to manage your newsletter preferences.

This is not true, however. If you have v-brakes or center-pull brakes, release them. Only 4 products can be compared at once. Oregon Pennsylvania Nevada Colorado. This is more likely if you have the semi-horizontal or slightly longer drop out slots found on steel (and some alloy) frames. A SRAM Powerlink is safe to use and makes life easier, but the whole process can be tricky and involve a lot of trial and error. 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. A singlespeed is noticeably quicker and easier to pedal than a multispeed bike in the same gain ratio. A three-to-one ratio between chainring and cog seems to be the current popular favourite. Thread the adjustable cup (preferably steel) down past the mark and cut, using it as a guide. Add 42mm for a normal headset, plus a few spacers just in case (four 5mm washers). Okay, some might think that opting for just one gear is jumping on the trendy bandwagon, but by converting an old steed, youll be taking part in a venerable and virtuous tradition.

If your single gear is low enough for off-road climbing, it will be too low to spin on the descents. You can invest in equipment to change your fixed-speed ride into a multi-gear unit yourself. Coaster-brake hubs have a good deal of internal friction, and coaster brakes have a number of serious drawbacks: Short-reach caliper brakes and modern MTB rim brakes, either traditional cantilever or newer direct-pull styles can lock up either wheel at will, but also permit fine control over the modulation of each wheel's brake. A singlespeed bike dispenses with the weight of the derailers, shifters, cables, extra sprockets and longer chain. I STRONGLY recommend starting out with fixed gear. 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. Note, there are two types of hubs called "flip-flop": The cheapest way to convert a multi-speed bicycle into a singlespeed is to use the original rear hub, assuming that it is made for a conventional threaded freewheel. You can never over-grease, especially if the bike is used for winter training. If youre really lucky, you could end up with a chain length that works without the use of a tensioner. Size and cut your brake cable housing to the correct length, making sure theres enough to accommodate turning the bars, and dont use indexing gear outers.

While the single gear ratio will not be the "perfect" gear ratio for all conditions, in the conditions which fit the single gear, it is considerably more efficient mechanically than the drivetrain of a derailer bike. Paradoxically, a singlespeed is, in another sense, more efficient than a multispeed bike! Turn barrel adjusters all the way in, anchor cable rmly and put a crimp on the exposed end.

Because you usually switch feet before restarting, it is impractical to use toe clips and straps, or clipless pedals. Options are described in our article about derailerless drivetrains. Its a good idea to place a metal washer against the inside edge of the freehub body as a rst space. Generally, for street use, with a freewheel, I would recommend a gain ratio of around 5-5.3, for instance, a 42 tooth chainring with a 16 or 17 tooth sprocket. You can get away with a little left or right variation, especially with a 3/32in (derailleur type) chain. 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 "flip-flop" hub.

A well-lit, quiet working area, i.e. Generally, your order will ship UPS if it weighs over a pound, and Postal if it weighs less than a pound.
