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)

I need some advice to get started on parts...(picture of my Cannondale frame)

Here's a ~16-20 year old Cannondale frame I found in my buddy's garage that was once his older brother's. For good measure, I called up his brother that lives far away if I could have it. He could've cared less about the bike, as it had been sitting in my friend's garage for the last 10+ years gathering dust and rust.

There is nothing that was brazed on for me to remove. There were basically plastic clips that held in the brake lines that popped right out with a set of pliers. So now there are holes in the frame, but those are standard.

Is this thing made of aluminum or something? Part of the tube is a lot thicker than the rest. (On a side note, there is also a Centurion bike of the same vintage, in the same shape. His older brothers were twins...I'm wondering if that is the better bike to turn into a fixie).

So I'm wondering if anyone could tell me what exactly it is that I need to buy. I have no clue what size to look for on anything. The only thing I know about a bike is how to ride one. I am pretty good with tools and minor fabrication, as I used to be a mechanic.

I'd like to make this thing a fixed gear bike with just a front brake. I have the handlebars, but I don't know how to take off the brake. Any advice?

There doesn't seem to be anything to pop off so I can access a screw or anything.

If anyone could PM me links to specific parts i would need, or just PM me the sizes.

The only thing I know is that the neck says "0.875" which I'm assuming is the diameter. That's about it.

Also, how do I tell what size bike this is? I rode it once when I was 13 years old, and it fit me pretty well. I think I was about 5'8 or 5'9 back then...the bike was still in fantastic shape back then. What part of the bike do I measure to figure out what size this is?

Squeeze the brake handle and look inside... you'll see a hex bolt in there. You can unscrew that to get the handle off.

Read around on sheldonbrown.com

It covers everything you need to know and more, and it has a whole page on fixed-gear conversion. I don't think anyone here will have the patience to spoonfeed everything to you... It's all on Sheldon's page, spend two hours reading all that's relevant to you. Come back with specific questions afterwards.
Start with the page on dropouts. Yours looks vertical, which will make life a bit difficult. Here's the link, the last one you get from me: http://www.sheldonbrown.com/fixed-conversion.html

Frame size: measure the seattube and the top tube center to center in cm, tell us how tall you are and we can make a guess if it's at least close to the right size.

Frame material: I'd guess steel. If a magnet sticks to it, it is. Otherwise, aluminium. The fork may not be the same material as the frame.

Yes, it is definitely pre 90's.

I rode that thing before I was able to drive, and that's been over 16 years ago. In the mid 90's, the only bike I was on was my 600cc Suzuki.

As for the other tips, the problem with Sheldon's website is that there aren't hardly enough pics!

not the aluminum. All the other parts. Like the derailers, screws, brake lines, chains, etc.

That's not going to fly, he has vert dropouts. Unless he gets one of those super expensive hubs.

or if you have vertical dropouts buy a set of horizontal dropouts and have a welding shop cut and weld them on maybe. i dont know if this is legit with an alluminum frame but might be worth looking into. or find someone to trade it to for a better frame.

I's say the price is the only thing this frame has going for it as a fixed gear. The vertical dropouts will make either your gearing selection or hub selection small. For a cruiser, aluminum isn't as nice a ride as steel. I'd probably go with the centurion.

Well, one, people who can't google/site search for themselves deserve their fate... I'm sure the OP can.
