Dolphin Grey Track Pack of 2 for Nautilus CC Plus, Nautilus (Old), Oasis Z5i, DX-Series, C-Series

It works but it was painful to assemble because of how tight the track was which is good because I know it would not come off. My fingers were shot after pulling the track into place. This worked for my nautilus cc plus.

I bought the cheap ones before these. You get what you pay for. The other ones were very stiff and brittle. They cracked in a few months. These seem very pliable and sturdy

Replaced the tracks on my Nautilus cc plus. Cover held in place by 4 Philips head screws. Replacement is not difficult just wind new tracks around the pulleys. There are YouTube videos that will help. Nautilus now climbing and working perfectly.

I just got these this afternoon which I was happy about. They came 5 days earlier than was stated originally. I purchased knock offs that came off the second time in the pool. I put them back on and made sure that I had them on correctly, which I did. The knockoffs were a breeze to put on as they were a little loose. These factory tracks were much more difficult to put on because they did not stretch like the knock offs did. I believe that these will stay on and for the extra $20 they will be worth it. I will edit the review if I have any trouble but I don't think I will.

They work well but they occasionally come off. I would have given them a 5 star bc they are sturdy but they fall off at least once a week.

Once I figured out the installation (by installing the center guide wheel last, using it to pull the track up into place), they fit snugly and will hopefully last a long time. They look durable and seem to be doing the job, for several weeks now.

It was a bit of a pain to get on and almost felt like it was going to pop off once it was on but once I replaced the side cover and screwed everything in it fixed my issue. My issue was that the original track would fall off and cause the unit to jam and stop moving. I would take it apart to put it back on and it would work for a short while before falling off again. Been working great ever since!

I initially purchased third party tracks and they soon stretched out and kept coming off the wheel. OEM is the way to go!
