TRANGO Quantum Quickdraw Extender with AtØmic Dogbone – 10cm, 20kN | Ultralight Sport Climbing

Ultralight power for sport climbs

Meet the TRANGO Quantum Quickdraw Extender, a careful blend of minimal weight and dependable protection. Featuring a 10 cm AtØmic dogbone and a 20 kN rating, this setup keeps weight down on long ascents while maintaining solid performance when you pull on it. At approximately 52.5 g, it sits among the lightest options in its class, making it a compelling choice for routes where every gram matters—from long redpoints to quick, dynamic sequences between holds.

Best-in-class handling for smooth clipping

The design prioritizes effortless clipping and snag-free movement: it includes the largest gate opening and the narrowest dogbone among ultralight quickdraws, complemented by a double-bent wiregate and a partially-hooded bull nose. This combination helps gear move cleanly through holds and stays out of the way during transitions.

• Ultralight powerhouse: 52.5 g with 20 kN strength
• Best-in-class handling: largest gate opening and narrowest dogbone among ultralight options
• Snag-free clipping: double-bent wiregate and partially-hooded bull nose
• Durable, UV-resistant AtØmic dogbone

AtØmic Dogbone Technology

The 10 cm dogbone uses our proprietary AtØmic weave, delivering roughly 20% more strength for the weight while offering improved UV resistance compared with traditional Dyneema. The result is a lighter, tougher core designed to endure exposure on sunlit crags and staging turns between attempts.

• 10 cm length, 24.5 cm overall for compact performance
• 20% stronger and lighter than traditional Dyneema
• Enhanced UV resistance for longer life in sun and heat
