I just (finally) got the Bontrager Charger Flash pump, and I’m not a fan of the universal chuck it comes with. Especially because it does not really bite or seal onto presta stems that have had the valve core removed - it just blows right off. Sans core is the only way that I seat my tires, and for a hand pump designed to seat tires you would think they would make the chuck work without a valve core. I swapped the stock chuck for a more cheap feeling but better working SKS dual valve Chuck I got from Amazon, but I’m wondering if anyone has any better suggestions, at least ones that feel nicer than the SKS one.
