my first kit didnt come with nylocks and I was a total mechanical noob, but i know the reason my spokes twisted was because I didnt properly secure my sprocket bolts. either way, if he properly installed his rag joint, he would not be having this problem.

The sprocket is supposed to be hub-centric, meaning it centers on the hub. If your hub is too small, you'll need to fabricate a hub-centric ring. The rag joint is not sturdy enough to prevent the sprocket from shifting.


m_b_f, we've established that it's got nothing to do with loctite so please, stop recommending it. Like you said, you are a mechanical newbie; building one bicycle didn't magically make you an expert.

The kit supplied sprockets are not designed to be "hub centric" or self centering Cavi, there's far too many different hub sizes for that to be feasible, let alone the different sprocket manufacturers & their questionable quality control.

While it would be nice if they were and the idea of making an adapter ring isn't a bad one - the fact is the vast majority of the rag joint sprockets installed by our members have no adapter ring and as the sprocket's center hole is too large in most cases they're adjusted and centered by hand, with a gap between the sprocket's center hole and the hub.

Every one I've installed has at least 1/16" gap or more and yet when properly adjusted and toqued they have remained in place without shifting - while I'm not a huge fan of the rag joint method of adding a sprocket, they are more than strong enough to prevent the sprocket from shifting.



Simply put, your advice isn't always accurate either. Like you, folks are simply trying to offer whatever experience they've managed to acquire - I suspect there's no such thing as an "expert" in that there's always something more to learn, someone else that's done something differently and there will always be someone that knows more.

I would ask that you remember that when replying.

I use the spin it and see if it woobles test if it woobles then you have more work to do.
If I feel like being real picky I will use a magnetic base dial indicator.
Check for both roundness and side to side. Makes it real easy if you number 4 evenly spaced spots around the sprocket that way you never loose track of the spots your trying to measure

We haven't established that loctite wouldnt help, in either case it wouldnt hurt anything, I have built more than one bike, never said I was an expert, I didnt say I am a mechanical newbie, I said I was a noob when I built my first bike. I have learned a lot since I first started, What I offered was an educated suggestion based on my own experience. If you cant respect when other members offer their help and experience, then you dont need to be here. And I only recommended loctite once.
