Singlespeed & Fixed Gear - This is a really bad idea.

So i have this bike layin around collecting dust. How crazy would it be to actually weld on a track cog to the wheel. I mean it's not like im gonna re-use the wheel or anything. This would be strictly for playing around, and at the same time experimenting a little. Is this the dumbest idea ever, or could it work.

thanks. jdb

it could work.

Depends on how you do it, but there's no reason it couldn't theoretically work.

dumb idea just loctite it and use a brake.

use jb weld.
holds better than loctite.

You'll probably find it quite difficult to weld a steel cog on to an aluminum hub. Let us know how it goes for you.






You're probably better off with some JB Weld and a brake.

I once rode with a guy in Philly who welded his cog to his hub. If I recall correctly, he did so because his hub was completely threaded and was otherwise useless. I am not sure if it was a steel hub, but I assume so.

duct tape would be way more punk rock

unless its a steel hub, it wont work. and why waste a cog when you can loctite/suicide hub?

We know a guy that just won an alleycat here that welded his cog on using a pencil torch and pins as solder. he'd been riding like that for some time, and he's incredible fast.

Incidentally, during that race, his seatpost broke, and he rode the rest of the way standing up.

what's your point

Never heard of that approach, but you could get a freewheel and weld it so it's no longer 'free'. That has been done.

Disclaimer: don't ever do this! Your wheel will explode and you'll die! Not responsible. Ipso facto. Etc.

Suicide hubs make you a better STREET RACEERRRR

JB weld it. Let it harden a for couple of days then your set up. Work fine as a suicide hub you can even skid with it. Keep the brake on, someday it may fail then your lean why it's a suicide hub :D

Go for it, man! Be sure to use a really low gear ratio so you won't be tempted to ride fast, and you can do fun tricks like backwards circles, etc. Do the ridiculous with the bike.. mount crazy stuff to it, put a 20" wheel on it..

take some pictures, it should be fun!

what's your point


that it works.

If I was going to do something like that, I'd weld/loctite on one of those Miche splined cog adaptors.

Of course, after you've spent $25 for that and $25 for your first cog, you could have been well on your way to buying a real hub.

What about covering the threads in flux, rotafixing the cog and soldering it on? It should be atleast a little stronger than jbweld

aeon flux?

a lower gear provides more torque, so you are more likely to slip the cog off from skidding/backpedalling.

Don't break a spoke.

just leave it outside in the rain for a couple of months. when the aluminium hub oxidises and steel cog rusts they should be imovable

Suicide hubs make you a better STREET RACEERRRR

Painted-on lightning bolts help TONS.

aeon flux?

Liquid Television?

If you do it with a pencil torch and paper clips it's soldering, not welding. The difference is that the materials you're joining don't get melted. It would be easiest to do with a steel hub, which let's face it are usually free of charge, but a good TIG welder could do it with a steel cog and an aluminium hub. You or I probably couldn't though.
