Hi there, yesterday I changed my EQ E to winter bikes. Afterwards I wanted to check the air pressure, or set it right. I had to remove the valve caps. Unfortunately, it seems that it is not so easy with the rim without the tool to be comfortable. The valve is very short and deeper installed, probably to reduce the air resistance. And the whole is in an elongated section in the rim. So you don’t just come directly with two Fingers to turn, to screw the cap away. I got the caps away, however, it is a frigging, if the rims are dirty then it will not be better for the finger. In addition, the cap would have fallen in the back twice almost the rim. When looking at it similar grieving play. The rim is the aerodynamic original AMG 19 inch. These were purchased as complete wheel set from Mercedes, so should also be used or is there still a tool to unscrew the valve caps? Or am I simply dubious? Greetings Al
