You need a frame which has the sort of dropouts that enable you to move the wheel backwards and forwards to adjust the chain, most commonly horizontal dropouts.
The common vertical dropouts keep the axle in one fixed place.

Then all you need is an Allen key to remove your rear dérailleur and a chain tool to remove some links.
Everything else can just stay there. :mrgreen:

If you have a bike fitted with a freehub (cassette) type wheel then you could splash out on one of these to get your chainline right.

Or you could just split your cassette and move things about a bit.

The easiest way to keep the chain tensioned is to put your dérailleur back on.
Though by this point you are losing all the advantages of a single speed and might as well leave things just as they were. You can just disconnect the gear cables if you want. :wink:

If it does have vertical dropouts, you should probably give up on that frame for SS use and get another.

The cassette has three small bolts or rivets running through it, they can be undone or the heads drilled off. The bolts are not needed when a cassette is fitted to the freehub and the locknut properly tightened.

Yes.I made this one from bits i had to hand.It swings out the way for wheel removal :D
If you want to do it cheaper,get just the sprocket and use spacers from an old cassette given to you by your LBS. :wink:

A few manufacturers sell kits with all you need for under £20. Try looking at DMR singlespeed kit, Gussett singlrspeed kit or Superstar Components. Kits usually contain a single sprocket, a tensioner and cassette spacers. I run a bike with a tensioner, along with 2 sprockets. The tensioner has enough range to run either gear, quite handy for longer rides.

It had 18,freewheel not cassette on the back.It was being chucked out,so i`rescued`it.
It`s great fun for local trips,and has made me re-assess what i thought of Aluminium frames :shock:
As an unexpected bonus,It`s also the only bike i have that i feel confident to ride`no hands`. :D

Young Ed, just do it as cheap as you can get away in the first instance. If the bug really bites, then fine, replace/rebuild with better bits as time and finance allow. I'd say go with Milfred's idea. You can get the kits on Amazon too (unless you're an Amazon hater ofcourse), in fact, what can't you get on Amazon?!

I've got "a few" bikes now, but the two fixed and two singlespeed freewheel bikes get ridden the most without a doubt.

If you have a cassette hub at present this is the easiest way to do a conversion. If you don't have a cassette hub then it is a slightly expensive way of buying a tensioner.
