Kind of Grinding?
Hello, IXNS owners. Do you feel kind of grinding when the gear is set at 7, 8 or 9? 9 is more obvious and 7 is slightly. Other gears are pretty smooth and silent. I wonder what is with that. Will chain lube help?
By the way, I found the rear tire is also 20x1.5, not 20x1.75 mentioned on the webpage. Kind of weird. They have too many 20x1.5 or what.
