Unable to loosen IXOW Wheelguard Gravity nut I have a Canyon Commuter 7.0 which uses IXOW Wheelguard Gravity skewers and nut. I want to take my front wheel off but am unable to loosen the nut on the front skewer.

The standard procedure is to flip the bike upside down and then loosen the nut. This does not work. The instructions state that if the nut cannot be loosened, it should be tightened a little before loosening as doing this should release the locking mechanism. This approach worked for the nut on the seatpost clamp (which uses the same type of nut), but has not worked for the front wheel.

The recommended tightness for the front wheel nut is 5-7Nm. I've already increased it to 8Nm when tightening in an attempt to loosen - it slipped at this point, so I don't want to try much more force in case I damage it.

I've tried flipping the bike upside down a few times, to no avail. What else can I do to try and loosen the nut?
Exact same problem here. Same bike. I got it off finally by just turning really really hard using a non-torque wrench. Make sure it's rotated so that the two dots are UP (12 o'clock). If installed correctly the lock should be at 12 o'clock when wheels are on the ground. So if you installed it in the wrong orientation (i.e. lock at 2 o'clock or 9 o'clock etc), then turning it upside down will not be the correct position. So rotate the bicycle around until the two dots are at 12 o'clock.

You can see from my photo it seems that when tried to loosen it, the tab on the black washer that is suppose to be in the fork dropout rolled into the plastic dropout insert which was causing it to bind. Going to write Canyon about this to see how I can get it repaired. Same thing happen to you?
