Today, high in the White Mountains of California, equipment failed me.
The Easton EC90 XC 29er rear wheel valve began leaking badly. Why should a valve just start leaking? I could see the Stan’s sealant bubbling out around the valve. Even after tightening the screw nut (hard), it still leaked. How does one plan for a bad tubeless valve? A tire is one thing, but a tubeless valve?
Then my brand-new Lezyne pump fell apart and then after reassembly stripped itself onto the wheel valve, so I had no pump to inflate a tire or tube.
After 3 miles of walking from about 13,000' feet down to 11,600', I was able to bum a ride back to my car, where I installed a tube and inflated it with my floor pump (after destructively removing the Easton tubeless wheel valve with the stripped-on Lezyne attachment). I had food and water and warm clothes, but I was sure glad to skip the extra 6-7 miles of walking back to my car.
