Yes, they’re confusing and the instructions – such as they are – are confusing. It’s almost impossible to explain as well and a ‘finished’ picture won’t help much either. The three holes bit folds back and is secured by the bolt/sleeve assembly, different holes give different angles for the blade. The soft, grippy strip sits around the seatpost under the Velcro strap which holds it in place.
I broke my first one, the guys replaced it FOC – great service – and promised me an updated one if the new failed, so far it’s been okay and quite effective, I’d say 75% if the Mudhugger (on another bike) is 100% and it’s super light and easy to remove and replace.
Hang on, I’ll try and take a pic of it…
