|My new project...||OwenMeany|

|After I got my CT1 this summer, I set aside the Lemond Zurich awaiting inspiration of what to do with it...
I have decided to turn it into a fixed gear or single speed..(new paint first from Joe Bell)..Which would you do?
I have been doing some searching for what it will take to do either job. Does anyone know of the "defintive" site for a SS or Fixed conversion? I think I know what I need but I am getting my information from verious sites and I am afraid something will fall through the cracks..
Things like: Do I need a new crankset? I cannot seem to get a solid answer to...
Thanks in advance for your help, jb

|Was this a conversion project for you?
Are you using a flip/flop hub?
What cranks are those?

|sheldonbrown.com and rbr fixed gear are great resources.
I had actually written a lengthy reply, but it did not post, hmmm, let me try again.
The two site above are great places to start, but will not be definitive. Unless another poster has converted a Zurich just like yours will you find a step by step process to follow.
Depending on the type of fixed rider will determine the answer to your questions, which is why you hear so many different answers.
For example, many fixies are hard core and ride only track or dedicated fixed gear bikes. These may tell you that you will need to buy a complete pista grouppo in order to correctly convert. Others, like myself, will suggest that you change nothing unless you have to. I converted my first fixie for $9.95.
I started with a Fuji Club with horizontal drop outs. Does your Zurich have this type of drop outs? If so, the conversion is much easier. If not, you will have some measuring and ring calculation to do. Sheldon Brown can help with that. If you need to use a chain tensioner, you will not be able to go fixed without some risk to yourself or the drive train.
Since riding the fixed, I found that my area just had too many hills around the house. I have since converted a Bianchi into a SS. I enjoy the SS more because I no longer feel like I am going to be thrown from the bike on a 35mph decent. However, somewhere inside of me I feel like I am no longer part of the elite group of fixies out there.
Part of the experience for me was to just dig in and see what you can come up with. If you get stumpped, post the question on the fixed gear board. These posters know what they are talking about. You may even find one that has done his/her Zurich.
To answer your questions to me:
All the parts are pretty stock, except for the bmx single speed freewheel.
Most everything is older Shimano 600, cranks, brakes and etc... On the pic I actually had 53X18 combo. That was fun on the downhills but too hard on the knees going up. I have since moved to 48X18.

|a very clean conversion (meaning no chain tensioner which sounds like a pita and doesn't look great) can be had with a eccentric rear hub. Sheldon discusses them and has them for sale on his website. Not for the budget ss though since they are around $230 and I'm not sure if they can go fixed. The SS winner of J's cx races here uses one on his IF Planet X. It looks good and goes damn fast.
I'm still working out issues on my old SSMTB. Chain keeps hoppin.

|Try what you have and see if the chain-line is acceptable. Square taper cranks make this a little easier because you could choose different BB widths to get chain-line perfect.
If you are stuck with a certain BB crank type there are still options. The norm is to put the chain ring on the outside of the crank spider. If that chain-line didn't work you could put the chain ring on the inside. Chainring bolt spacers could also be used but probably won't be neccessary.
If you are uncertain about FG vs. SS, I'd highly recommend using a flip-flop hub. If you plan to build a wheel anyway, it doesn't cost any more. It's nice to have options.

|www.fixedgeargallery.com. Mostly dedicated to photos of peoples fixies, but the wealth of information is the fact that most of the photos come with the person's description on how they did the conversion, along with their e-mail address. They've got hundreds of photos, so there may even be your bike in there.
Otherwise, Sheldon Brown and the fixed gear discussion group on rbr are excellent resources.
If you can get a good chainline, you may not need a new crankset. Minimally, if you want a decent fixie or SS, you'll probably want a different drivetrain (crankset, chain, and rear hub and cog). This can be a relatively minimal outlay of cash, especially if you're handy pulling things apart and putting them back together! If you can build a wheel, you're set!

|to help with gearing and avoiding the use of a chain tensioner if the Zurich has vert drops
I would have to guess that Sheldon Brown is the most complete site for fixed and ss.
