The Fizik Antares R3 saddle is part of the further developed Spine Concept. Before, this just looked at the flexibility of your spine, but now it takes the way you ride into consideration as well. The rotation of your pelvis is essential to determine whether a saddle suits your needs or not. There's now both a Regular (130 mm) and Large (152 mm) version available of the Fizik Antares R3. The faster you ride, the lower the pressure gets on the saddle, requiring less surface area for support.

The Fizik Antares R3 has been designed with the so-called Chameleons in mind. According to Fizik, the Chameleon is a rider with a fairly flexible spine. The Antares saddle is a mix of the Arione and Aliante when it comes to the shape. The saddle offers great support in every possible position. The Chameleon bars have the same shallow drops as the Bull version, but the reach of the Snake bars. The Fizik Antares R3 is a lightweight and rigid saddle. This is because of the Carbon Kevlar thermoplastic composite shell, Wing Flex technology, and K:ium rails.

Saddle shape
This saddle has a semi-round rear part which makes it perfect for those who move around a little with their hips while riding. A semi-round saddle provides ample support while also offering enough freedom to move around, and more so than a flat saddle.

This is a semi-round saddle, which means it's flat at the front and raised slightly in the rear. The shape makes it suitable for people with a fairly flexible spine. This has to do with the rotation of your pelvis. For instance, when you're upright you might need a little extra support, but when rotating forward to ride on the drops you're fine.

Fijn zadel!

Zadel is hard maar zit heel fijn. Ik moest wel wennen aan het ruw leren/suede toplaagje. Je moet in een keer goed gaan zitten. Anders kan je koersbroek een beetje “kleven” aan het zadel.


  • Hard zadel
  • Voelt de fiets goed onder je
  • Makkelijk af te stellen
  • Geeft steun aan zitbeen


  • Prijzig
  • Suede toplaag is wennen

Mooi zadel met kliksysteem voor tasje waardoor 100% afstelbereik van het zadel behouden blijft

Qua maatbepaling zadel (regular vs. large) gaat Fizik niet uit van de afstand zitbotjes maar van het gewicht en gem. snelheid van de rijder. Dit is hun spine-concept-evo. Bij het uitpakken van het zadel las ik hierover in bijgesloten boekje. Met het volgen van systeem/tabel van Fizik kom je mogelijk op een andere maat zadel uit.

Perfekt sittyta

Efter mätning av mina sittknölar bestämde jag mig för denna sadel. Ett perfekt köp för den kräsna baken :)

The K:ium Rails are made using an aluminium alloy and ensure a secure connection between saddle rails and the seat post.

Wing Flex Technology
By adding a slight amount of flex to the side panels of the saddle, Fizik has increased the comfort significantly. The Wing Flex technology creates a little extra space for your legs, allowing you to put out more power with more ease.

ICS: Integrated Clip System
You can attach a FiZik Saddle Bag or Light to the rear of the saddle with the integrated clip system (saddle bag/light not included).
