I’ve just taken a Maxxis Crossmark (2.1″) off my Arch rims after about a thousand tubeless miles. Just too floppy now, and has started burping (during a race 🙂
But until then I was very happy with it – went up with just a track pump and soapy water when it was younger, and worked well in both dry and muddy conditions (29er, rear).
Maxxis Ardent worked well on the front until the weather got too gloopy, and I’ve now got Bonty Mud-x up front, and 29-3 at the back. Pumping like a loon is enough to get them on – not had to use CO2. The Bontrager’s are quite tight fitting though – you do need to _want_ to get them on.
