Got them on my Bird Zero AM.
The only issue I’ve had is the Trail Boss on the rear likes to get stones/trail clutter stuck in the outer knobs due to the larger size (Wasn’t an issue when running 2.4s) This could be due to where I ride. Normally they come out by themselves, but a few times I’ve puled over to remove it from the knobs.
Now running a rear Proguard to protect the back of my head/back from trail clutter flying up, I also had to tap up my chain stay where it joins my seat tube as large stone flying down on it didn’t do the paint job any good.
Weird reply but being honest.
Tires are ace otherwise. will upload a photo in the morning.
Cheers..
