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.

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

  • Twin Bar Anatomical Flex

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

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® material moves in all directions and behaves as a second skin thus reducing friction between rider and saddle.

  1. JCAPSASL1020

    I bought this saddle to go with my new GT Avalanche 1.0 .Best thing I could have purchased for my butt.If my butt could talk it would say THANKS .Anyhow this seat is great for upright riding comfort.

    Already recommended to my little brother for his GT.

    In my fifties, needing exercise, I took up cycling. My first saddle seemed too hard so I got a wide/soft one. As my distance increased I developed a perineum problem so serious I’m almost embarrassed to write about it. I had some internal bleeding. I thought I’d have to quit cycling but some online research led me to the Serfas Rx saddles and the Hybrid” model immediately solved my problem entirely. No more pain – no more internal bleeding. Now”

    This saddle is proving to be a good match for my upright riding position. The full-length centerline cutout is a big advantage.

    After trying two other saddles, the one that came with the bike as well as a second one that I purchased from the bike shop to alleviate the pain from the first one, I went searching online for a saddle with a reputation for comfort and good reviews. I compared numerous saddles from several suppliers and decided to buy the Serfas HY-RXL. My choice was based on the design and the reviews plus the width was similar to the current saddle I was using and I didn’t want to go any narrower.
    I have cycled over 30km on it and I’m very pleased with the comfort and elimination of the soreness I used to experience with the other saddles. I ride once or twice a week for recreation on an e-bike and I spend about an hour each session riding 16 to 20 kilometres.
    The saddle is just a little, but not too much, softer than the other seats. However, the cutaway section in the middle is what really makes the difference, eliminating the pressure that the other saddles apply on the groin. The Velcro material is okay; it isn’t slippery and I hope it is durable, but time will tell.
    I highly recommend the saddle to anyone that is looking for a more comfortable ride. I’d also recommend two other things that are important to avoid discomfort from riding:
    1. Make sure the saddle is no higher than the handle bars, lower is better
    2. Make sure the saddle is level. Don’t have it sloping up from rear to front. Sloping down from rear to front very slightly is also okay too.
    I ordered the saddle online, with the cheap postage option, and it took about one month for it to be delivered to me in Australia. It was well packaged and I could follow its progress with the tracking number provided.

Always great to hear from a satisfied Serfas© customer and we are of course especially pleased to hear how well the RX Cruiser Hybrid saddle has helped alleviate riding pains for you. We hope you continue to rack up those miles and do so in comfort! Thanks again, Cheers! – The Serfas Team
