LezyneTwin Speed Drive (Return to Product Page)

Sold or gave away three other chuck designs. This one fits in my wallet bag nicely and has worked flawlessly for the last 3 years.

Not a cheap date but when you have a puncture you need high quality that works effectively. Component is very robust in material and design. No leakage during operation and the neoprene C02 cartridge hand protector is an added bonus. Suggest using up a C02 for a "dry run" to get the feel of the operating characteristics.

So glad I could find this CO2 chuck. I love it because there are no moving parts to seize after years of getting wet and abused in my saddle bag. In my opinion it is the very best on the market.
