K, so I am total n00b when it comes to anything on the pavement. I'm planing on building up a SUPER CHEAP fixie or SS conversion in the near future. The problem is I only have a cassette hub so I can either make that cassette hub fixed...or go SS.

I know welding the cassette hub has been covered in the forum and will not work because of the different metals, but what about JB weld? More-so, where would be the best places to place the JB weld?

And don't worry, I will be running a front brake and a very low gearing.

edit: No Surly Fixxer either.

came up in another thread today actually

https://www.fixedgeargallery.com/arti...anula/freehub/

I would do it the "easy" way and pack it into here:


dissasembly instructions here:https://www.icebike.org/Equipment/freehub.htm

I can't imagine JB Weld will handle any kind of torque, but I've been wrong before .

Dude....W O R S T I D E A E V E R....do you want to hurt yourself. You can do a budget fixie for sure, that is part of a fixie's charm...but the drivetrain is NOT that place to half ass it or cheap out on.....

You can bolt it together ... https://www.fixedgeargallery.com/arti...anula/freehub/

I'm not sure I totally understand whats going on here, but it seems he has created a bumbike fixed gear thread on hub from a a weird old freehub? He is using a bottom bracket lockring to hold on the cog so theres a chance it could unthread unless I'm mistaken.

To the OP. Just use spacers and run the bike SS until you are ready to buy a fixed wheel. Nobody will make fun of you and you won't destroy a hub in the process.

Bad, bad idea.....ugggh.

formula hubs are too cheap to be riding around on suicide hubs. $50 for a hub, or a couple thousand for a hospital visit, your call.

joke or not, still the best argument for a suicide hub.

The rims I will be running aren't even worth lacing to a $35 hub.

I might just have to sit out of the fixie club for a while until I get some money together for a track wheel. I hate bikes, they eat up all my money.

I don't see why packing a shimano cassette body, prawls and all, full of JB weld wouldn't hold. The prawls will be locked into position against the inner track surface of the body for forward movement, and for backpedaling the prawls will A) be "glued" into place, and B) be "wedged" into position from underneath .
I doubt the torque from a wheel could come close to compressing a solid wedge of steel and JB weld.

Try it out. You're running a brake so the worst thing that could happen is that you lose drive and have to walk it home.

or suddenly lose control & crash...

made plenty of ghetto hubs, all welded, they all broke.

just my $.02

Yeah, JB Weld is nice, but the forces that fixed gear hubs take are pretty darn big. I wouldn't chance it. No, that's a lie. If I was flat broke with nothing to ride and had a hub like that lying around, I'd totally give it a shot. Just fill the sucker up and ride if you want, but I predict catastrophic failure.

I just don't see it happening. So after some play develops the worst thing that can happen is that you can freewheel...sort of. Then what?

I would think that welding would be entirely different, unless you were able to reach between prawls with ... flux core? What else would fit?

could always pour lead in the cassette body...

Yeah but you would need to heat the cassette body too, if want any sort of adhesion(sp?), and i hear thats not good.

Get some Epoxy (JB weld) and fill it up, make sure there are NO air gaps, if there are i think the JB weld will just shatter, which will end up in freewheel mode again (but crunchier lol).

how to fix your hub.

step one - buy bike
step two - ride bike
step three - want new bike
step four - hate current bike
step five - explode into a spouse battering rage
step six - set bike on fire
step seven - high five your friends
step eight - post pictures on bike forums
repeat.

i jbwelded my cog and lockring back on after stripping the threads. has held up great for 4 months and im 210 lbs

holy crap that is tight!

do the JB weld and tell us how it goes!

FWIW, lead has a much much lower strength, in compression, than JB weld. Heating up the steel cassette body will do nothing to it except burn out all the grease.
