What do you think about this:

As i posted earlier my WTB disc lite hub is trashed. I'm going to make it fixed temporarily and this is how my friend and i are probably going to do it. any input or feedback would be great.

We are putting a larger cog off an old cassette on the inside of the freehub body, adding the needed spacers and then putting on the cog i want to use in the proper chainline. Then, wrap strong wire around the large cog and the spokes to lock the hub in place.

voila, fixed gear...

Not a good idea...

It probably wouldn't be good to introduce stress to the spokes in a place that generally stress doesn't originate from normally. I would suggest looking at www.63xc.com for a solution that uses the disc side of the hub to attach a fixed gear.

non

You wouldn't believe the incredible stresses put on drivetrain parts whilst backpedalling fixie style. The rear wheel "wants" to keep turning, and it takes a LOT of leg power to stop said wheel or slow it down.

I reckon you'll snap them spokes off like butta.

I sorta figured. I ride a fixed gear 52x16 to work most days and definitely see the major stress i put on the drivetrain. I was hoping maybe a 34x18 wouldnt be so bad.

i like the 63xc websites drilling idea and i think i'll give that a shot if i can find a drill press to use here in NYC.

I thought I read something about an easy fixie solution. IIRC, it involved filling the freehub with JB weld.

I have no idea how well this will work, but can't beat the price, eh?

Everyone seems to be skeptical, but I can say that I've done it and it works. I had a old trashmo 10 speed that I made into a fixed gear by tying the freewheel to the spokes using an old derailler cable. It was supposed to be a trashy commuter and it looked the part, so as you can guess it's not the best way to go. But it did work and the rear wheel didn't explode.

If it has a removable cassette like a shimano hub does, you could have someone weld the outer splined body to the inner lobed piece that interfaces with the hub. Or heck, drill some holes through the outer body into the inner piece and screw it together with a couple of sheet metal screws. Or as someone suggested, disassemble and rebuild it filled with JB weld or epoxy.

34x18 is worse

With a lower gear you are putting a lot more torque into the drive train, and you'll be amazed at how much stress is placed on it in a low gear off-road. I've gotten a couple rides in now on the Boone fixed cog set up (mounted to the disc rotor mounts) and its so stiff that I can feel an alarming amount of flex in my cranks (RF Turbines) and, even more alarmingly, actual wind-up at the hub flange/spoke interface! I don't think you want that same interface to be holding your cog on (albeit, not for long!)

just get a new cheapy rear wheel to tide you over. you can get a deore disc wheelset for like $100 at a mail order place. take the front and make a fixed gear if you feel like it, but you can just use the rear wheel and ride and not risk your teeth with experimental equipment. just my opinion.

i could get a surly hub and rhyno lite for 119 but i feel like i'm wasting my money because i dont want that wheelset or the one you mentioned. hollywood told me last night he uses a regular king disc hub with spacers and has had no issues so i'm considering that now since they are readily available.

i was worried i would trash the king hub too but apparently they are the same thing as the SS specific.

cool. by the way, i read the thing about 'la ruta' and i give you a lot of respect for that.
i have been to costa rica and it is a truly wonderful place. although you might be suffering too much to notice!

The masochist within me was quite pleased when i signed up for the race and failed to allow the rest of me to fully understand what i was really getting myself in to:) I was reading stories a few weeks ago by people that have ridden it but have since banned myself since i felt they werent helping me any! I still want to ride a single speed...i truly hate geared bikes and know it will frustrate me when i start getting chain suck from all the mud. plus granny gear blows. to me it seems easier to stand up and mash in a comfy 34-21 all day!

that's what I do when my pawls break

that's the standard backcountry repair for trashed pawls. I've used fence wire, zip ties, and toe straps. Trashed probably 10 hubs or freewheels on my tandem and on singles, have yet to have to walk. Trouble with your idea is, the ploy usually tweaks the rim's trueness by tugging unevenly on the spokes. It's a great emergency thin-air repair, but pretty crude for an everyday ride.
What's the great attraction to that particular hub? Any threaded hub will do the same thing without muss or fuss and allow you to use a quality EuroAsia or comparable cog.

Have you considered getting a Rohloff Speedhub? I don't have one but have read really great reviews by people who have ridden them in extremely sloppy conditions. It would work well on a singlespeed frame with horizontal drop-outs without a chain tensioner. (You probably know this but It has 14 equally spaced gears over a 24 gear range in a sealed rear hub.)

It is expensive, but it sounds like the La Ruta race is the ride of a lifetime and might be worth the effort. They are apparently easy to resell on EBAY.
