The Fizik Tundra M3’s fiberglass thermoplastic composite shell has Wing Flex™ that is designed to help with freedom of thigh movement supported by K:ium rails. The Tundra shape is flat, narrow and long ideally suited to Snakes.
K:IUM is a fi'zi:k proprietary rail formulation. It's the combination of a particular metal alloy, a specific tubular design and a special finishing process which increases fatigue performance on the rail surface. Fact: 8% weight reduction compared to solid titanium. K:IUM features a high strength-to-weight ratio grade and high corrosion resistance.
Wing Flex Technology
Wing Flex shell has engineered flexibility along the edges where the inner thighs contact the saddle. By allowing this area to flex, the rider can achieve a full range of leg movement in a wide range of riding positions. Wing Flex allows the saddle to adapt to the rider rather than the rider having to get used to the saddle.
Integrated Clip System
The Integrated Clip System (ICS) is an integrated interface in the saddle's base to allow quick attachment and removal of ICS accessories such as the Fi'zi:k saddle Pa:k and Blin:k light. It is a clean, easy, fast and secure attachment that does not require any tools.
Tundra M3 is for The Snake: Flexible Spine
If you are very spinally flexible (far less than 90 degrees between your straight legs and your back when bending over as far as you can, keeping your legs straight a shoulders’ width apart), you are a Snake. You achieve the performance position using your spinal flexibility alone, not rotating your pelvis at all. You will like the flat, narrow and long shape of the Tundra.

Performance saddles are narrower than the models designed for shorter ride comfort. They're intended for riders who have a committed riding style with weight on hands and feet so they're narrower and lighter. High tech padding materials and flexible body designs keep your pressure points comfortable and lightweight chassis components keep the weight down. Most have some kind of ergonomic design to reduce pressure on nerves and allow unrestriced blood flow to your sensitive areas. Womens models have a wider design to suit their naturally wider pelvis. Saddle widths vary across the ranges from narrow (upto 130mm), medium (upto 138mm) to wide (upto 146mm). Narrower saddles are the popular choice for longer distance riders as they do not cause the hips to be placed in an unnatural position. Wider saddles will often feel comfortable initially due to their greater surface area but then progressively decrease in comfort as the miles increase, the correct choice of saddle is a case of getting the balance between initial comfort and overall comfort.
Fi’zi:k is the premium, racing brand of Selle Royal S.p.a. Its name is synonymous with the shape and form of the human body; hence the intuitive association with products that are contact points between riders and their bikes. More than this, fi’zi:k represents beauty, speed, passion, freedom for those who race against each other, race against the clock and for enthusiast cyclists around the world who identify with the feeling of the fire of competition. The humble origin in 1998 stemmed from a vision to improve rider performance by creating superior saddle comfort. Today’s Spine Concept™ provides a guideline to help riders find their most comfortable saddle. Integral to this comfort is the design collaboration with professional athletes and the fact that each saddle is 100% “fatto a mano” (hand-made) in Italy. Some credit Fi’zi:k with redefining the racing saddle category thanks to its destructively-innovative elegant products that are not only comfortable, but also a source of style and beauty in their own right. The Arione, launched in 2003 is one such example. In 2006 fi’zi:k launched a product for riders’ hands: a strong, washable Microtex bar tape. Shoes were then launched in 2010 offering a unique blend of innovative materials with an inimitable style. 2014 sees fi’zi:k launch road cockpit components employing The Spine Concept™ to help riders choose their perfect handlebar shape. In 2013 fi’zi:k saddles were ridden by 8 out of the 19 UCI World Tour Teams. Fi’zi:k’s relentless innovation is facilitated by many such committed professional athletes, from all cycling disciplines. Relentless testing and refinement has helped fi’zi:k to push the boundaries of possibility. It will come as little surprise then that Fi’zi:k products have been ridden to many Cycling World titles, Ironman World Championship titles and beyond.
