Converting my bike to fixed - Component advice?

[Taba]

Hi guys, I picked up a Raleigh R:100 road bike a few years ago for £180. Used it tons and like it alot and I'm used to it. However I have thrashed the hell out of the gears, they are pretty screwed now and only work kind of dodgily, there is visible wear on the back chainring bits (sorry, bike noob) and they are basicly screwed.

Anyway I want to convert it into a fixie. I'm moving from the countryside to Manchester and reckon since all the hardcore couriers ride fixies they must be best for in town. Read alot about it and sounds like fun, especially the proclaimed "oneness" you get with the bike, useful for staying alive round town no doubt!

Ok now my question; I have read alot of the stuff about converting on Sheldon Brown etc, and feel like I could pull most of it off myself, however I am on a v tight budget and will be looking to buy parts off ebay, forums or any special deals. I was wondering if I could use your experienced heads to help me each step with finding which parts I need and how much to pay for them, where to compromise and where not to?

Your help would be greatly appreciated!

Dont just do it because you think its the best thing to do, because the couriers do it. Couriers also ride gears.
The good thing with fixed is that its simple, and you dont have to maintain much. You might like it, you might not.
Anyway, hes my advice.
Get a good crankset thats designed for fixed. 1/8th ring, with a 1/8th chain and 1/8th sprocket. Good solid drivetrain.(dont bother anyone saying im wrong becausde 3/32 is better, its different thoughts and this is my thought)
If you have the money, get a good rear wheel built. If its good enough, it will last you a very long time, and shouldnt be too much. When i first built up a fixed, i had a solid rear wheel built, and its lasted me onto my new fixed, which is better, and is pretty much perfect after havign alot of knocks.
If you want to just go cheap, get a rear wheel that takes a screw on block, and just put a fixed sprocket on. You might need to put a spacer onto it to get chainline right though, and you wont have a proper lockring thread, so if you dont put the sprocket on right then you might have the sprocket come off.
There are a few ways in which you can lock on the sprocket. You could also use a BB locking as a lockring for the sprocket.
Having a back brake when the set up is like this could be recommended so there isnt as much back preassure on the sprocket.
The rest im guessing you can just use what you already have.
You may already have a back wheel that takes a screw on block, so you can just take that off, put on a fixed sprocket, get a new chainring and ride it as fixed.

I built a fixed up for the cost of bar tape by asking people in my club for fixed stuff/was offered a crashed fixed and got given it, so it just cost me for bar tape.

My first fixed i built up using second hand bits, and it was only the bottom bracket and rear wheel that was new, everything else was second hand. And that lasted me well, most of the stuff i have used to build up my cheap bike(including the frame after i stripped msot thigns off it for my new build)

If i were you, i wouldnt just go fixed because couriers ride them, and so think they must be better in town. You might find it more difficult in town then a geared.
If you want the hipster look however..........

Doesn't the R100 have vertical dropouts? (the slots which the rear axle sits in) If it does then it's a poor candidate for conversion since you'd either need to find a 'magic gear' (which will never be ideal) or buy special eccentric hub that's worth considerably more than the bike.

If you want a cheap fixed your best bet might be to look for an old steel frame with horizontal dropouts. There are lots around and Sheldon gives lots of guidance on converting them as you know.

Heres my cheap bike.

Heres my expensive bike, that i do alot of miles on(crap picture)

Ive got 6 bikes, and only 2 of them have gears. MY TT bike is fixed aswell, i get on alot better with fixed then gears, other people cant get on with fixed/dont like it as much as gears so dont ride it.
My expensive fixed has only had one problem so far, and that was the rear wheel bearings going, thats been it.
My first fixed had a few problems because it was built up cheap and i rode it alot.
My chepo fixed now doesnt get used alot, so is fine, but i wouldnt like to ride it far.

Re-reading my original post it does sound like maybe I haven't thought about it and I'm just trying to be cool on a fixie. But actually one point you make is the really important one ro me; simplicity and robustness. But also I have tried a fixie BMX when I was younger and LOVED it, i'd love that feeling back.

I reckon the stuff on Sheldon Brown should see me through mostly, I was just wondering if this forum is the right place to ask about individual components that I see on ebay etc, so that I can get a view as to whether they would be suitable. Hopefully I will find a helpful bike shop in Manchester who wouldn't mind giving me good advice on it aswell as lending me tools and stuff.

On the point about vertical rear dropouts, yes you are right they are. I read on sheldon brown that you can grind them out a bit to give you some play though. Has anyone tried this, how did it work out?

My budget will be sub £100!

Grinding out vericle? Pointless i think.
Look at the ones on my yellow fixed, they are forward facing horizontal and are fine. Its what i have on my cheapo fixed. Dont confuse forward facing horizontal with verticle.
I wouldnt bother with building a frame up with verticle drop outs personally, but i guess if thats all you have........
As i say, my build up cost me the price of the bar tape, now the grips. Thats it.
My good one cost me alot, more then what i paid for a geared bike.
There will be people on here that can help you parts wise. For good cheap sprockets Planet X sell them for like £14.99, i have one on my good bike ands its nice, and not a bad price.

 

[Joe24]

Oh, and with the magic gear, you have to work it out, and know that to gear down/up, know how many teeth to take off the front, and add on at the back.
Not as easy as when i need to change gear and i just turn my wheel around/put a different sprocket on, instead of having to change chainring and sprocket to get chain tension right.

 

[MajorMantra]

It's probably possible to get it to work but honestly, why go to all the trouble of a conversion when the dropouts are inevitably going to be a source of angst? Since you need to replace most of the components anyway I think you might as well start with a more suitable frame.

It's not uncommon to see complete 531 framed (=good) bikes for £50 or less in tatty condition and ones of these could be converted with a suicide hub as Joe was suggesting above.

You could just make the bike single speed?

Then your frame/dropouts will be fine. You wouldn't need to bother with any of that lockring trouble. In fact you could probably get away with just a new chain £10, and a BMX sprocket, £20. (Use your old rear mech as a tensioner).

 

[Taba]

Hmm, looking at my rear dropouts I am pretty sure they would have to be grinded to allow any lateral movement for tensioning the chain. I guess this would realistically mean grinding it down in order for me to make it work, or this magic gear business.... which sounds complicated!

I suppose I could ride my current bike and very slowly build up a fixie on the cheap aswell. It would be a shame though as I really like everything about my bike except the gears, which are really on their last legs (i use one most of the time anyway to avoid crunching noises!).

Any more advice appreciated!

I had thought about this before I set my heart on going fixed. It would be alot better than the mess I have right now. The brakes levers I have are combined with the gear levers, which would be a bit messy and extra weight, but I guess they would still work... Seems like a half-way job though.

Realistically, what is the cheapest I could build a decent, robust, relatively light fixie for. Perhaps after selling my current bike (a few weeks without a bike aaaaargh!) I could get close to the sum needed.

 

[Joe24]

Just looked up your bike on the internet.
If i were you, i would just sort out the gears on that bike. Theres no point in grinding out the verticle drop outs.
Then what i would do, is find a decent-ish frame thats going cheap/free and slowly build up a fixed using decent-ish new/second hand parts.

There's no simple answer to that question. If you have a local bike charity or a recycling centre or something where you can scrounge then it could be very very cheap. If you have to source everything online then it will cost a bit more. If you go for a suicide hub it will be much cheaper but in the long run you'll probably want a proper fixed hub.

Ok, decided to build a fixie from scratch on the cheap. Try and keep my old bike going whilst im at it, I don't think I could live without a bike for more than a couple of days as I cycle everywhere and cry if I have to pay for a bus.

I suppose if I'm looking for something like this to get started?

Yes, however some bits for Pegeot bikes are harder to get.
Try and avoid somewith with singlespeed in the title, might find it cheaper.
