Years ago while Josh was working with the Team CSC at the Dauphine Libere, he noticed one of their mechanics using the most amazing little chuck to manage the disc wheel inflation. Unlike anything he had seen before, it was all metal and used a 'lollipop' lever on the side to lock onto the valve stems in disc wheels. The mechanic explained that these were made in Japan and were coveted by all the Euro-Pro mechanics due to their scarcity. So Josh set out to improve the design and make it available to cyclists everywhere. - Full metal construction, guaranteed for 25 years and covered by SILCAShield - Can effectively seal on valve stems as short as 10mm! - Uses SILCA 254 High-Tech Elastomer gasket - Adjustable gasket pre-load allows for a custom fit on any valve as well as compensation for gasket wear - Male Schrader thread fits into any Schrader chuck, or use SILCA Thread-On Schrader Adapter to fit a bare hose - Bullet-proof high-pressure, disc-compatible chuck for high-pressure situations.

With a conjoined secondary chamber that can be manually pressurized, Lezyne's Digital Pressure Over Drive floor pump is capable of conveniently seating tubeless tire systems. An integrated foot-lever opens and closes the chamber; when the chamber is full (Max. 220psi / 15 bar), flipping the lever down creates a powerful, continued blast of air that can seat road, mountain and plus-sized tubeless setups. This provides tubeless users an effective alternative to air compressors and CO2 units. Furthermore, a highly accurate digital gauge is incorporated into the pump for precision inflation when filling low- or high-pressure tires.

Tattico is a highly efficient mini-pump with an ergonomic design that makes it easy to use in all conditions. - Tattico has 4 unique features: - Inverted Design: Tattico is designed backwards from most pumps. The hose and valving is hidden inside the inner tube rather than the outer cylinder delivering up to 10% more air per stroke compared to pumps of similar length. - Adaptable Cup Seal: Other pumps seal with o-rings which lose effectiveness as friction heat increases. The Tattico Adaptable Cup Seal grows with the tube, resulting in ultimate efficiency at all temperatures. - Hidden Heat Sink: There is a heat sink hidden at the end of the barrel which absorbs a high percentage of the heat generated when pumping. This keeps the rest of the pump cool, even at high pressures. - Twin Tube Insulated Grip: Tattico handle uses 2 thin tubes separated by an insulating air gap to keep hands cool. This results in better grip and control without risk to hands even when inflating multiple tires to high pressures. - 6061 Alloy barrel and gripping surfaces - High-efficiency piston design - Long extractable filler hose with locking Presta/Schrader chuck - 120psi - 9-1/2" length - Includes direct-mount bracket with retaining strap
