Im running tubeless for the first time and was wondering if any of you guys have problems with air slowly leaking out when the bike is left to sit a couple days? Im running Hutchinson Spiders on Crossmax XL's and when the bike sits for one evening they lose about 20 psi and when they sit a couple nights they are almost completely flat. When I pump them up they have seemed to hold fine for a 2 hour ride but im just getting tired of pumping them up before every ride.
