9T ! We did it
9T not only increased the range, but also reduce the weight of the system, because there is a greater range allows you to use a smaller chainring, also reduces the risk chainring hit stone

Light weight and strong, a perfect balance

Write at the end
No matter what cassette you use, first, make sure the derailleur hanger is straight. you can use a hanger alignment gauge to check. In fact, many people know this, but when we get the new cassette, we couldn’t wait to install it, so we forgot to check it, why are we reminding you here? Because this situation just happened, a buyer, he said that the cassette of other famous brands can work normally, but ours can’t. We discussed this for a long time, and finally we found out that it was caused by the bend of the hanger, which was interesting. When we find that some famous brand cassettes can still be used when the hanger is bent! (of course, not perfect, there is some clarking noise) it is always difficult to admit that others have done well, isn’t it? That’s ok, we will continue to work hard and improve product performance, now we can guarantee that our products work good as well as famous brands under normal conditions. Thank you for your support 🙂 Best regards.
