My 2012 Salsa Mukluk 2 has SUNringlé MüleFüt rims on it, but I’ve been having intermittent leaking around the valve stem since receiving them last summer. It turns out this is because the single rim wall keeps the the WTB TCS Valve stem from being tightened down far enough to make a good seal. By adding the white nylon washer seen above — spares from a Velocity Velotape set — I can tighten it down enough to make a great seal.
With some 45NRTH Hüsker Dü tires put back on the bike, set up tubeless, it’s now ready for spring time. If only the trails were as well…
