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'm looking for a place to get relatively inexpensive 104bcd (4 bolt) chainrings. I'm looking for rings in the 34-38 range. Odd size rings would be nice but if they are at a premium, then forget it.

I have/want to run two-speed on my "Single" because the way home requires a <50 inch gear. No, I'm not a weakling, I've been climbing this for over a year. And my current set up (32x18, 46.1") is pathetically slow on flats.

I'm looking to run 32x18 and 36x12, or 34x18 and 38x16. I can take up to a 2 tooth slack.

Thanks

I've always wondered about the possibilty of a multi-speed (3 at most) fixed. Sturmy-Archer (sp?) made a fixed three speed hub back in the day, but that's probably harder to get than these chainrings. How about a flip flop hub? you can put a 25er on the otherside, and use one of those surly tensioner jockey wheel thingys to deal with the extra slack....dunno, just some ideas

you can't use a tensioner when running fixed.

Right now I am riding on my mountain bike. *sigh* vertical dropouts *sigh* aluminum frame. I may get a Eno hub later on. Or nashbar has a steel mtb frame for $100, but I like the frame I have now. If someone could reweld dropouts for me for not so much, I would be crazy happy.

I have the Surley tensioner now and It can take up a two tooth slack before I have to add another section of chain. I want to run 16 and 18 in the back because that is what White Industries has for their 2-speed freewheel.

Somewhere on line is an outline for making a 2speed fixed gear outa a S/A 3 speed hub---sam (or you could build a Hirondelle 2speed and backpedal up hill)

I've been thinking about tackling this. Would eliminate the need for a tensioner...

White Industries claims to be close to releasing a dual fixed cog. They also ellude to it being matched to a special hub. It would almost have to be.

I've asked some 3-speed hub manufacturers if they can modify a 3-speed to make it fixed.

They get a very funny look on their faces.

It took me eighteen months of talk to get them to understand flip/flop fixed/fixed hubs. So don't hold your breath for a 3-speed fixer.

Actually, the ASC was up on eBay a couple times, about 6 or 7 months ago. The first couple times bidding only hit ~$300, which was below reserve, and then I lost track of it.

Now, if I made $100k/year, I would have been all over it...

Thse are the kind of things an enterprising person would invest to produce...another one is a street fixed tire, super thick with multi colored layers, so you know when enough is enough...

sheldon brown says that you can modify a 3speed internally geared hub to be a two-speed fixie. he might include directions or further info... i forget. but it is a 3 to 2 conversion and i strongly encourage anybody to try it and then give me the hub, especially if they succeed, cause that would be cool.

a dual fixed would be awesome. Since they also have a dual freewheel it would complete the line. I wish they had more choices than the 16/18 and 17/19 dual freewheels. Maybe some with a 3 tooth gap, or a 14/16.

To clear things up, I'm not riding fixed right now. I just have a regular cassette hub with 1 cog.
