Hi Amir,

I have two possible solution out of probably many: 1) Make a lock ring that fits the threads you have. Any good machinist should be able to measure what's left of your thread, and make something that is a tight enough thread that it will work and be fine. This can either be from scratch, or if you can find something that has a smaller ID than what you need, it can be enlarged. 2) If the cog is a good fit on the thread and you tighten the cog onto the hub with a chain whip, you can get by without a lock ring. It's better if you have a front brake, but I rode like that for years around San Francisco on hills. A lock ring is better by a LOT, and it all depends on the fit between the cog and the hub, so it MAY not be a good idea to NOT have a lock ring. My best
solution is in #1!
