Invert is the Worlds First Gravel Fork. Invert smoothes your ride and gives unbelievable control of your bike on rough roads, loose turns, and steep descents. Its surprisingly lightweight, easy to use, and strikingly attractive. Until this point, no fork made for drop bars has been able to combine the smooth ride, lightweight, simplicity, and good looks into one complete package. Riding beyond the pavement can be rough, physically taxing, and unpredictable. Invert goes straight to the source of this problem to offer a smoother ride with more traction, both uphill and down. With Invert, youll be more efficient, more relaxed, and have confidence to glide over gravel like youve never experienced before. Rider Benefit Focused: Invert gives your bike unbelievable amounts of confidence and control & makes Gravel more enjoyable. Lightweight: Only 990g, or 2.2 lbs for Invert SL and 1113g for Invert CS. Good Looks: Striking, sleek looks integrate perfectly with the simple lines of drop bar bikes. Easy to Use: Intuitive, single click Climb Switch is easy to operate while riding even with gloves. No other complex tuning necessary. Materials: Carbon fiber and premium aluminum construction. Two Travel Options: 30mm SL Model and 40mm CS Model. Invert CS: (40mm) Features Climb Switch that engages a firm setting for out of the saddle pedaling. Invert SL (30mm): Shorter travel and no Climb Switch for a more minimal and lightweight option. Single-Step Set Up: Just set air pressure using shock pump and RIDE. Adjust to desired level. Inverted Design: Promotes smoothest possible operation, lightest weight, & cleanest visual integration by using a layout opposite to conventional suspension forks. Gravel-Specific: Tuned, progressive air spring balances traction with the right amount of support and is fully adjustable for rider weight. Hand-Built In Fletcher, NC. TWO MODELS INVERT CS & INVERT SL Invert CS comes with 40mm of fork travel and a Climb Switch button that when clicked, dramatically reduces the amount of fork movement for pedaling out of the saddle. The Climb Switch button is inspired by the simple click of a pen, and is as satisfying to click as the feature is to use. Invert SL is a more minimal and lightweight option. It forgoes the Climb Switch mechanism to reduce weight even further and comes with less travel 30mm. This shorter option may also be preferable to some riders that want to keep their stance on the front of the bike lower. LIGHTWEIGHT Invert is upside down relative to the layout of traditional suspension forks. This unconventional design offered us the chance to build the lightest gravel fork possible. The main body of the fork is made with a novel, hybrid carbon and aluminum structure that is noticeably lighter and far better looking than the alternative. Invert SL tips the scales at less than one kilogram. Thats about 2 pounds.
