Anti-Torsion, Lower forward pivot, Active Suspension technology 의 약자 입니다...

ATLAS™ Technology: Anti-Torsion, Lower forward pivot, Active Suspension technology is Ellsworth’s single-pivot solution for riders seeking legendary Ellsworthian suspension performance, in a simple and affordable design. NEW for 2003, our patented, one-piece, 5-axis CNC-machined Anti-Torsion tube (see inset) ensures flex-free energy transmission between the rear swingarm and main pivot for incredible stiffness, precise tracking and powerful sprinting. Active Suspension provides a smooth, lock-out free ride while sitting, standing, coasting, pedaling and braking. ATLAS is incorporated into the Joker and Isis bikes, and it emulates the feel of ICT so well, it consistently outperforms the rest of the industry’s best four-bar linkage bikes—with an enhanced single-pivot design that could only come from Ellsworth.

Why does ATLAS™ perform so well?
True to our "no compromise" mantra and unlike corner-cutting competitors’ offerings, ATLAS pivots are precisely located on each frame size, ensuring optimized performance for all riders. This attention to detail ensures a carefully-tuned, linearly progressive shock motion ratio for a consistent, compliant ride over any terrain and throughout the complete travel range—for larger or smaller frame sizes. Ellsworth’s "no compromise" Mantra applies to ATLAS single-pivot technology too!
