thats what happened to my brother in laws wilbers he was never confident with them after that and so went back to the oem item shame cos they were easier to adjust with having the seperate resivour when i used his bike
Pothole was big, but not enormous, just the bike was loaded with all the camping stuff, girlfriend and the pothole was after a rise, so the bike in this pothole with big force. The speed was ~30km/h. Seems that touratech parts worked out well.
