Okay, here's what I've done:

I started with a cheapo 27" single speed wheel. I rotafixed my cog on there with red Loctite on the threads and JB Weld between the cog and the hub. I then put on a BB lockring with JB Weld between the lockring and the cog and on the threads. I then tightened the lockring on with a hammer and screwdriver until it wouldn't budge. I haven't used this wheel yet since I did this yesterday after work. I'd like to try it today but I'm a little nervous so I'm tapping the glimmering fountain of knowledge and experience that is this forum.


Here's what's bugging me:

First, using the rotafix method, I was never sure how tight I was supposed to get it. It felt pretty damn tight but I was afraid of stripping the hub's threads since I did the same thing in a roundabout way with a similar hub a couple months ago. Second, I put on too much Loctite which ended up running in between the JB Weld and the cog/hub. Would this weaken the bond between the JB Weld and the metal?

I might just be worrying too much. I am running a front brake. Every metal-to-metal surface has either JB Weld or Loctite on it and is pretty tight. Has anyone else done this method with success? Should I wait longer before I take it for a spin? What is the meaning of life? Have I told you lately that I love you?

Thanks.

r0cket-

That's what I don't like about the rotafixa method--it should hold against skipping and skidding assuming you get the cog tight enough, but there's no real way to know when it's tight enough.

I don't think that cog is ever leaving that hub. Just use a front brake in case it does, and have fun. People have been skidding for years on JB Welded hubs, and its not pretty, but it is secure if you do it right (and it sounds like you did).

Are you sure you used enough product? Maybe some krazy glue, duct tape, and nails would make it more secure. Then that cog won't come off until armageddon.

Okay. I'm being an overcautious wiener. Imma gonna go ride.

And thanks.

always a good idea to run a front brake on bumbike wheels. Better safe that not safe.

your cog is less likely to break loose than someone using a proper track hub. congrats.

You should probably round off the edges of the lock ring, as a further preventative to discourage removal- although if you ever DO decide to remove it, you should de-spoke your wheel first so you have absolutely no leverage.

Actually, you will find out in a hurry if your wheel will work. My only concern is that what you think might be tight using a hammer and screwdriver may not be so tight in the real world. That all said- I have a wheel with just loctite- no JB Weld and no lock ring- but best of all- no problems.

"always a good idea to run a front brake on bumbike wheels. Better safe that not safe."

of course, the same could be argued for track-hub wheels.

Well, I totally lost my cog and lockring while trying my very first skid. Didn't react fast enough and plowed into a 'bent rider which caused me to endo into a hotdog stand, lacerating my chin and burning about 30% of my face. 10 stitches, a couple rolls of gauze/sterilizer, and a lot of appologies later I've decided to have a friend weld, real-weld, the cog onto that damn hub. By the way, I'm lying. I had a great ride. Except for nearly losing it in front of 2 hot runner-chicks when I tried to coast over a bump. But that happened only once.

By the way, what does it mean when a liar tells you he's lying?

Here is my bumbike story:

So, to fix my rear hub, I soaked the cog and hub threads with off-brand blue loctite, and used the roatafixa method to get the cog as tight as I possibly could. I used all my 140 pounds to really crank that sucka on. Then I sqirted more loctite on, and spun a $.50 old bb lockring on, and hammered that thing on with a chisel and 5# sledge. It's held fine for almost 3 months now, and I've been skidding/skipping/doing hard backpedaling/resistance in that period. Works for me.

I also changed the cog once, and that thing was almost impossible to get off, but I did it.

I have always maintained that modern pharmaceuticals, oops I mean chemicals, can achieve fine results.
