is there other options to replace the back ring on the cb6000? Mine has broken 2 times so far . Acrylic does not seem to be the best option. Took 3 weeks before the first one broke and another 2 week for the second to break. There must be a metal one or different type of plastic that would work.
If you want a metal ring then you ought to really be considering metal tube or cage to go with it. Maybe a chinese cb6K stainless knock off...or similar. or a HT2 maybe.
write to @kink3d - he makes replacement one piece rings that are much stronger and likely comfortable than the ring it comes with.
Do yourself a favor nd upgrade to a better cage. I had 2 of these and both split along the seem on the tube. It isn't a fun pain to wake up to.
Hey! Sorry for the late reply, and thanks @josielynn-jewell for the referral. Yep, I have replacement CB-6000 rings up on my Shapeways shop that are more comfortable and less fragile than the original plastic rings. I make the O-Lock in all 20 ring/spacer combinations, so you can pick whatever size is best for you. Check it out and let me know if you have any questions!
