Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

fixed speed ? again

So if I have a standard road bike - I am thinking about converting to a single speed .
Do I buy a hub that is designed for flipflop will this aline my chain up correctly( or do I need a chain singleator on top of the flip flop hub)?
I hope that ? makes sense,
John

forgot to ask this also- Does it really make a difference if your frame was built for a fixed or not?
I mean I see post saying you should have the rear axel slide in from the back instead up from an angle -Why would this really make a difference?

mainly you need horizontal dropouts, in order to adjust chain tension. if you have vertical dropouts you will need a singleator to adjust chain tension. chainline is a different issue that will be affected, but not necessarily solved, by installing a singlespeed hub.

the following link will tell you all you need to know, and then some. enjoy.

Performance has parts to convert a roadie into a single-speed, but that will not be or feel the same as a fixed-gear bike.

Remember that fixed gear (no coasting) is different from single speed (only one gear, but with a freewheel for coasting). Old road bikes usually convert to fixed gear quite nicely. The easiest way is to buy a fixed gear rear wheel and cog, remove the uneeded shifter-stuff from the bike, and install a chain. You may need to mess with the spacing of the hub, or the position of the chainring to get a straight chainline.

Single speed is even easier, you need something to maintain chain tension (unless the bike has horizontal dropouts), and then a BMX freewheel, or a single speed kit for a cassette hub.

I suggest spending a lot of time at http://www.sheldonbrown.com reading about fixed gear and single speed. If you still have questions, come back and let us know!

peace,
sam

YES! Those dropouts are perfect for use as a singlespeed or fixed gear bike!

how about a hub like this?



its a flipflop apparently but i thouht they were to have stepped and reversed threads for a lockring?
anyone care to explain? could this be used for a fixie?

I am new and dont ride fixed yet but am looking for the cheapest way to convert possible..

That hub would sort-of work... But it would be a cludge. You could thread a cog on, but there would be no way to keep it on. You could use locktite or jb weld, but again, its a cludge. If you already own that hub, and don't want to buy anything, you could get away with it, but don't buy that hub.

I'd look for a 'real' track hub, which will have two sets of threads on each side. Like mentioned, Nashbar has their high flange track hub on sale right now, its 30$, which is damn cheap, and its a basic quality hub. It even includes lockrings, which saves you another 20$ down the line.

peace,
sam
