Great tubes. Daily 20 mile commuter hold air and very puncture resistant. No issues at all great fit.
Best, Tubes. Ever! These have removable valve cores.
Durable tubes that resist punctures and hold air longer than tubes by other brands
Presta valve is good
Thst retains more air over time.
Great tube for carrying as a back up. Long stem works for many aero and lightweight rims both. Not the lightest but it will certainly get you home.
