a little tips for adjustment

1. What is this product?

This product is a new 11-speed group set made from China. The most of the engineers in the R&D team worked in SR** before, and we have our own patents and technology that have not violated the patented technology of other brands.

2. How about the performance?

Our Competitor designed the X9/M780, so we designed the 11-speed group set which provides a very sensitive shifting response and a clear shifting feel. Because the design extended the maximum support of the 11-speed group set, this set can be used for 11-46T cassette with the extension of the hanger .Not only that, it’s cheaper and lighter than the competitor which has similar performance. Therefore, I think this group set is very competitive.

3. Is the installation adjustment of this set the same as other brand’s products?

Of course. We’ll try our best to provide help to you when you have problems in installing. It is not recommended for customers who have not installed such products before, since this product is a new product. Therefore, please purchase it after careful consideration, or go to the bicycle repair shop for help later to prevent damage to the goods during the installation.
