Mounting Compass Tires Tubeless

Here is an interview conducted by Jan Heine of Compass, with gravel bike racer Matt Surch about using Compass tires tubeless: https://janheine.wordpress.com/?utm_source=Retail+Customer+Newsletter&utm_campaign=ec662e1ce6-EMAIL_CAMPAIGN_2017_07_18&utm_medium=email&utm_term=0_f74fbd5ca8-ec662e1ce6-108609665&mc_cid=ec662e1ce6&mc_eid=2e5f71b642 . I was pleased that Matt shared my positive opinions of the 35 mm Bon Jon's, while acknowledging that because of rim design, supple side walls, mounting them tubeless can be challenging. In my case, I think that the combination of an old worn tire with very supple side walls, very thin sealing tape, and a rim perhaps less suited rims (these were slightly narrower Ardennes FR's, not the Ardennes +), all combined to lead to my failure. I'll probably do some more experimenting with heavier tape and a different rim to se if I can get my old Bon Jon's to seat. In the meanwhile, I've just ordered a new pair of Bon Jon's for my new custom bike and wheels that should be finished in a few weeks. As Matt says - the Bon Jon's are a true "Goldilocks" of a tire. Good for almost everything.

I thought only the Ardennes Plus was rated for tubeless use.

I have never owned them, but a few of my coworkers at the bike shop ran them. They often would install with a tube, remove only one bead to remove the tube, and then do the tubeless setup with one bead already locked in place from the tubed setup just moments ago.

Of course, YMMV.
