ATK Titanium U Springs with Rolling In System

ATK K08.2W Titanium U Springs with Rolling In System come standard on the Hagan Ultra World Cup and can be used to upgrade or replace worn traditional U springs.

The ROLLING-IN® SYSTEM improves ease of use and prevents wear and tear of the titanium “U” spring.

• ROLLING-IN SYSTEM®: Upgraded with rotating steel bushings, the “U” springs provide much easier step-in easy even in fresh snow conditions where stomping into the bindings can be difficult. The Rolling In System also eliminates wear and tear on the contact surface of titanium spring.
• The “U” spring is shaped out of titanium for extreme lightness combined with strength.
• RACE SETTING: the vertical release (My) of the U Springs are fixed at a certain value defined in the years by our athletes team to be the best balance between safety and stability.

Regular and Lightweight Options:

• K08.2W "regular" springs approximately My 9.
• K08.3W "lightweight" springs approximately My 6.

There are two reasons to upgrade to the Rolling In System U Springs:

1. Much easier step in making for faster and easier transitions.
2. They last longer. Much longer.

Expensive, but a very worthwhile upgrade!

ATK replacement U-Springs for Hagan Ultra World Cup and ATK SL World Cup and other bindings come in sets of two.

• 2 TITANIUM “U” SPRINGS with Rolling In System
• 2 “NEW DESIGN” CLAMPING SCREWS 
• 0 of the STANDARD CLAMPING SCREWS pictured in the photo

The "lightweight" version are called "lightweight" not because they are lighter than the regular titanium U Springs found on the HAGAN Ultra World Cup bindings, but because the retention value is lighter. The standard titanium U Springs release value is approximately 8 or 9, while the "lightweight" version is approximately 5 or 6. the Side notches on the lightweight version enable the springs to flex and release at a lower force level. (No claim of DIN value is made.)

So the "lightweight" name applies more to the skiers who may want to use these U springs -- lightweight skiers!
