i have been using the flows on my 29er, no need for tubeless tyres and they have been great. one day in 2 years a tyre was not holding pressure, the fluid had run dry
prior to that i was getting regular punctures, so from my perspective they are great
for the commuto x bike i will not be going tubeless just because i may want to change from slicks to nobbly tyres, if i could afford a spare wheelset i would be thinking differently
