Do Not Buy Cheap Chinese 11-50 cassette (READ Description 1st) VG Sport, Sunshine, Bolany, Ztto.

Update, this link will take you to Ztto video where they admit there was a problem with the cassette https://youtu.be/LbUDY9O8aaw

I'm open to the manufacture sending me a new cassette for review to test and see if the issue has been resolved.

This is a review of the VG Sport, Ztto, Bolany 11-50 tooth wide range 11-speed cassette and why I would not use one. If you just ride flat non-technical trails then it will be fine for you but if you ride technical trails you need to watch this. The manufacturer asked me to take out 2 links which I did and it made no difference. They then said it needed to wear in. I have done just over 100km by the time of this video and there has been no improvement in performance. I think that they just want to exceed the review time so I do not give them negative feedback. I'm open to and still waiting for what Ztto/VG Sports/Bolany say about this issue and will update as more information comes to light. Links below.

The bike is a Merida Big Nine Limited with through axle front frame it is designed and came with 1x11 Shimano SLX and Sunrace 11-50 cassette. The best budget 11-50 cassette is the Sunrace.

The comparison I made was to the Garbaruk 11-50 T cassette which can be found here http://www.garbaruk.com/
