a MUST for Presta type tubes,
Verified Purchase(What's this?)
This review is from: Kool Stop Brass Card/12 PV Valve Adaptor (Pack of 12) (Sports)
After switching to Presta type inner tube valve stems, I needed to purchase adapters in order to properly inflate my tires. Rather than just buy one or two adapters, I bought an entire card full for under $10. Now I have plenty in reserve, I can carry one on my bike, keep a couple near my air compressor and give one to each of my kids while riding. Makes inflating super easy. Great product.
Yes, I use my shop compressor, but just turn down my pressure regulator to the pressure I want my tires to be to avoid any possible bursting of my bike tires.
