I just mounted these tubeless on my stock Bontrager Affinity TLR on my Trek FX S6. Ironically...they lose the least amount of air of any of my tubeless road bike setups. On the road bikes they lose maybe 3-5psi overnight, whereas the GK SKs take several days to lose that same amount. I do run them lower though (50psi) compared to my road bikes (65-70psi).
