Hey all ~ I'm inclined to chime in because my tubeless setup is running
flawlessly this year. I hope I don't curse my luck by submitting this.
I've done tubeless for five years now, three years on CX. Fantastic
results on the MTB. Good on Road and marginal on CX until this year.
This year, I mounted Schwalbe Racing Ralphs on Stan's Alpha 340 Rims and
have not burped once. At 190 lbs, burping has been an issue no matter what
I run. What I did this year is mount the tires with tubes and let them sit
overnight @ 60 psi. Next day, I mounted tires w/out tubes and no sealant.
I USED SOAPY WATER AT THIS STEP ON BOTH SIDES OF THE RIM - THIS IS KEY!!!
Inflated to 60 psi and let sit for 20 mins. Then, I deflated and remounted
with Stan's. The tires mounted on just like the youtube video! These
tires went on great with no issues. I've done two CX races, smacked my rim
on rocks a few times and not burped or flatted. Double Cross was pretty
bumpy with a lot of flats and I came away without one burp or flat! I run
the front tire @ 35 psi and the rear @ 38 psi. This may be a bit higher on
the pressure side of things, but I am a heavier guy and I'm hoping that
improved bike handling skills will compensate for added pressure in the
tires. I will probably run less psi on a muddy day.
I hope that helps.
