This brilliant saddle is engineered for cross-country use as it offers superb comfort and reliability on every ride.

Ready for clocking up the miles, this stunning version is flat, long and narrow, so you can deliver a prime power transfer without losing the freedom of movement. It features a microtex cover that's incredibly durable when it comes to tackling all the challenges of a long day out on the road. Additionally, its nylon shell adds another layer of robustness to this already solid model, so you can ride with confidence and composure. 

K:ium Railed Cross-Country Saddle

Prepared for every ride, this reliable workhorse uses a k:ium rail construction that's 8% lighter than similar titanium models. As a result, you'll benefit from not having to worry about adding any unnecessary grams to your ride.

About the Fizik brand

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 1996 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 saw fi’zi:k launch road cockpit components employing The Spine Concept™ to help riders choose their perfect handlebar shape. In 2016 fi’zi:k saddles are ridden by 8 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.
