Adapters to make a Presta tire valve work in Schrader pumps are handy items to keep around, not just for their utility in the home shop but perhaps more-so for their use on the road where finding a kind soul with a Presta pump can be a chore as compared to the number of gas stations and garage foot pumps around with Schrader heads (not sure about the difference between Presta and Schrader? Check out Everything You Never Wanted To Know About Valves, Urban Velo #13). Due to their nature as a small removable piece these adapters have the tendency to never be in the right place at the right time, at least in my experience that seems to be the case. At least one other person thinks so, and thus the $7 Bullet Keychain was born, providing a simple solution that keeps the adapter with your keys, hopefully in a place you aren’t likely to leave behind.
Neat.
Combine it with a bottle opener and im sold.
I love it…but — why don’t folks just leave them screwed to the presta valve in the first place? You’ll never lose it that way!
Isn’t it simpler to just keep one of the 99 cent ones in the patch kit?
love this – so much easier to just keep on your keys right in your pocket
i gotta get me one
But my bike doesn’t need a key.
terry your officially a dork ~KC
I just keep mine screwed onto one of the valves, but there’s always that one dude who says “hey you left your adapter on your valve”, like it was unintentional.
I just rubberband the little one to the tiregauge in my seat pack. This is pretty cool, though, if you don’t already own an adapter.
I like to pad-lock my bicycle when I’m leaving it away from home so yes, I do need a key. Then again, what are the chances the adapter would remain with the bicycle if it was left unattended?
