How To Install ABS2 Chucks to Older Lezyne Pumps
The release of the ABS2 on the Year 9 line of floor pumps was a major improvement. This new chuck works for both Presta and Schrader valves and features a quick disconnect for Presta valves and an Air Bleed System button for easy pressure tuning. The ABS2 chuck is also sold separately and can be applied to older Lezyne Floor pumps. It’s also available in high volume (HV) or high pressure (HP) versions for mountain and road biking, respectively. We’ve gotten a lot of questions about how to convert older models, so here’s an easy guide to help you with your pump upgrade.
Unscrew the old ABS chuck from the hose swivel.
Use an Allen wrench (Allen 4 on the Lezyne 3-Way Wrench) to remove the swivel from the hose. If you own a pump with the crimped on swivel, simply cut it off.
Refer to this video for more in-depth instructions on swivel removal:
Twist off the compression nut of the ABS2 chuck and insert it on the pump hose.
Insert the ABS2 chuck into the hose.
Slide the compression nut of the ABS2 chuck up the hose and screw back on to the chuck.
Your newly upgraded pump is ready to prepare you for your next epic ride! Enjoy!
