TUFO(トゥーフォ)
バルブコアを取り外して装着するタイプのバルブエクステンダー
このタイプならば同じTufoからリリースされているシーラントも使用しやすいのでおススメです。
For high profile rims. An advantage of this extensions is given by position between the valve body and the valve itself. Protruding from the rim is the valve, not the extension thus making inflation, tyre pressure adjustment or complete deflation very easy. As the extension is provided with an o ring seal, no self deflation is possible.
Valve extension 31 mm
