Say goodbye to riding pains forever. Our RX line of saddles is the ideal choice to eliminate uncomfortable pressure and numbness around your sensitive plumbing by utilizing our clinically proven designs.

All Serfas® RX saddles incorporate anatomic-centered design and technologies to provide the best in comfort and protection so you can ride greater distances and for a longer amount of time.

  • Pressure Eliminating Channel

A deep anatomic channel through the center of the saddle allows maximum blood flow into the neurovascular bundle for drastically reduced numbness and discomfort.

  • Zero Friction Gel Infused Padding

Gel infused foam provides optimized saddle grip and support while reducing unwanted saddle friction and chaffing.

  • Twin Bar Anatomical Flex

Saddle halves rotate independently with the rider to reduce saddle friction and irritation.

  • Infinite Comfort System (I.C.S.)

ICS mates four unique layers of closed cell foam, gel, and microfiber materials to form a unified system of support and comfort.

  • Dual Density Base

Soft and flexible rubber-like material within the saddle base ensures the rider’s sit bones never contact a hard spot.

  • Pressure Reducing Two-Step System

Raised saddle tail profile helps alleviate pressure on the neurovascular bundle.

  • Four-Way Stretch Lycra® (*On Select Models)

Four-way stretch Lycra® material moves in all directions and behaves as a second skin thus reducing friction between rider and saddle.

  1. Jacob Jacques

    Extremely comfortable saddle with all the performance you need. I’ve done 100 mile rides with this saddle and never complained. Highly recommended!

  2. Adventure Bikes Xalapa

    Tengo el sillín desde hace dos años y es una experiencia única. Deje atrás las molestias que sentía el día después de pedalear. 100% recomendado.


    I’ve been super happy with this saddle. It fits me just right, without extra bulk or weight. The microfiber material breathes very well, but is smooth and easy to slide on. The saddle has held up perfectly for three years. I never thought such a sleek saddle could be so comfortable, but I was wrong!

      Michael, We’re stoked to hear how pleased you are with your RX-RR saddle and especially glad to hear it’s been serving you well for three years of riding! Thank you for choosing Serfas and for sharing your positive experience with us 🙂 – The Serfas Team

  4. Mark Taddeo

    Great Comfort on 40+km rides. I’ve been all kinds of Rider & Instructor. I prefer super stiff frames (Colnago Mexico Triple Butted, Cannondale F1000 CAAD4 & Giant XR Roam 1 ALLUXX) with 130psi (700c) for ultimate road contact. This saddle keeps the Competitive look with an amazing level of Comfort. If you have Spine, Nerve, Coccyx or Pelvic issues i’d highly recommend this for your flat bar, road or mountain bike. Keep riding, it’s good for you 🙂

  5. Ryan Speidel

    This saddle came recommended by my LBS and I’ve ridden over 2500 miles with the RX-RR. This is just an amazingly comfortable saddle and it still looks brand new to boot! Also it weighs 30 gm less then the stock fabric saddle on my new Cannondale.

      Glad to hear it, Ryan! Thanks for sharing and cheers to many more comfortable miles – The Serfas Team

  6. Joe DiSalvo

    Most comfortable road saddle ever. Period. I own a race and a performance and both are fabulous. My only complaint is Serfas needs to make a women’s specific version of the race and performance for my wife’s bikes!

  7. Joel Williams

    I’ve used this saddle for 2 years on my Trek X-Caliber 8 MTB and have almost 5000km. Excellent ride. Highly recommended

    • Serfas

      Joel, Thanks for the great feedback! We’re glad to hear how well the RX-RR has performed for you, cheers to the next 5000km 😀 – The Serfas Team

  8. Norman Conklin

    I just used this seat for 50 miles of rough road. I replaced the seat that the bike came with. I have zero pain in my rear end. Nothing. Zilch. This seat is extremely comfortable for long rides.
