Technical Details

- It's a lightweight XC frame that blends the high speed feel of a hard-tail with the comfort of a soft-tail through a revolutionary suspension design that converts 100% of your pedaling power into forward propelling energy - like a slingshot. Light and strong custom 7005 aluminum tubing with Slingshot Bikes' Sling Power suspension Technology translates into an XC frame you can build up with standard 26" MTB parts to create one head-turning and super-fast XC bike.
- Here's how Sling Power works: In a pedal rotation of a traditional bike design, there's a "dead" portion in the power stroke where you get no benefit from your expended effort. Slingshot's design provides an efficient use of pedal energy throughout the entire pedal revolution resulting in greater speed with the same expended energy. The pedal energy is stored in the spring compression - then released at the "dead" portion of the pedal stroke, effectively increasing the length of the power stroke. Any energy not going directly to the rear wheel (forward power) is momentarily stored, returning 100% in the "dead" portion of the power stroke.
- The Ripper uses 3 components to release the stored energy. The Dogbone Flexboard, located just in front of the seat tube provides independent mid-suspension. It's a fiberglass board that's self-aligning and replaceable. A Coil Spring, located where the head and top join, absorbs shock and stores pedal energy. The Stainless Steel Cable, located where the downtube would be, attaches to the Coil Spring and the bottom bracket. The cable links the front and rear frame components. When combined, the Ripper has the potential to turn every bump in the trail into forward motion by using stored energy. When you hit a bump, the front absorbs the shock by compressing the spring and flexing the fiberglass board which temporarily increases the wheelbase. On the return, the suspension redirects the force into forward motion. No energy is wasted.
