I'm looking to replace the hose (actually I only really need a new head) on
my Zefal Husky. The head is the Schrader with thumb-lock variety that has an
adaptor for presta. The rubber washer/grommet/seal on the presta adapter
wears quickly and leaks constantly so I'm interested in a new head with thumb-lock that
automatically adapts to both valve types and that does not rely only on
friction to stay on and form a seal. Something like the head on my new Zefal HPX
frame pump. I do need a hose/head combo for both valve types and am seeking
recommendations. Thanks.
