Details

  • A groove from tip to tail shifts rider's weight to inner thighs and buttocks, avoiding contact with the perineum, relieving pelvic discomfort
  • Also, the majority of rider weight is placed on the rear of the saddle, further reducing pressure against the perineal artery
  • Patented dual-density technology uses molded rubber inserts on base for shock absorption and an extra layer of Reactive Gel for added comfort
  • Hard frame provides excellent support and allows for increased ventilation
  • Compared to the men's RX saddle, the women's RX saddle design incorporates a wider back to accommodate wider pelvic bones and a slightly shorter nose

Rated 5 out of 5 by from Now I Can Ride My Bike Again I bought this saddle Saturday, June 11, and installed it on my mountain bike. Prior to this, riding had gotten too uncomfortable, even with padded biking shorts, and I pretty much stopped riding. I missed riding, though, and did some research online and decided my saddle was the problem. After talking with an REI associate, I chose this seat. Today, I gave it a test ride. What comfort! I wasn't a bit sore, and I wasn't even wearing my padded shorts. This seat is fantastic and I highly recommend it. BTW, I'm a plus-size woman. As horse-people say, "I'm back in the saddle again"!!

Rated 5 out of 5 by from Allowed me to bike again I had to stop biking last summer due to problems/pain "down there." What ended up happening was emergency surgery for a urethral stricture followed by a diagnosis of vulvodynia. Ladies, I cannot tell you how much constant pain I was in. I was not able to sit on my work chair, let alone a bicycle seat. 4 months out of surgery, 3 sessions of womens health physical therapy and this bike seat and I'm back in the saddle! I cannot tell you how great this seat is. Removes ALL pressure from the sensitive areas. All my weight goes onto my sits bones and nowhere else. Each panel moves independently. I can return to biking and getting the rest of my life back and it is great. Loved this seat so much I bought it for my sister who complains of painful riding.

Rated 4 out of 5 by from This Is A Great Saddle I build custom flat bar road bikes and this is my standard seat for women since you never get complaints and it helps to sell bikes. Sometimes I get people who like the Selle SMP series or the Selle Italia Diva more but most people are ecstatic for it and no one has ever had a major issue with it. If you have an OEM or hard seat, this will be a revelation for you. The ability to absorb road harshness is pretty much unmatched which with the great fit is what makes it so unique.

Rated 5 out of 5 by from Very comfortable saddle I bought this saddle to replace the one that came on my Novara FlyBy folding bicycle that I purchased from REI. Little 20 inch wheels, no suspension and the crummy included velo saddle (included saddles on bikes always remind me of the included earbuds with mp3 players...) added up to one big pain in the butt my first 2 days riding my FlyBy. I ride and commute in normal clothes (no bike shorts here) so I figured I should splurge on a good saddle. I replaced the stock saddle with this lovely plush bit of engineering and am now grinnin' and spinnin'. The bruises on my sit bones went away and now I feel like I'm floating along on a cushy cruiser. This saddle puts no pressure on my soft tissues and gives my sit bones plenty of padding. I especially like the way the halves move independently, giving it a little bit of shock absorption. I'm quite satisfied with my purchase.

Rated 5 out of 5 by from happy butt Put this saddle on my new hybrid bike. My 65 yr. old butt registered instant comfort. If my butt is happy, my rides are fantastic. Was so pleased, I bought another and put it on my mountain bike.....double pleasure! Cannot attest to the drying factor as it has not gotten wet yet as my butt has been on it in the rain. I chose this saddle because of the split design.....makes total sense to me.

Rated 5 out of 5 by from Love this seat!!!!! I purchased this seat a few weeks ago as the one that came with the bike (a Trek 2100 WSD) was comfortable but not comfortable enough for me (I'm 50-something). After looking at this in the shop, when I compared it to other seats (including those at the Trek store up the street), this was the most comfortable and lightest. Have ridden alot since having it and am always comfortable before / after / during rides. Not a bad cost for comfort.

Rated 5 out of 5 by from No more numbness! Perfectly designed and fitted for a female cyclist. Wide seat for our wide pelvic bones. Nose is not too long. The split runs the entire length of the seat. This has changed the quality of my rides! I am extremely happy with this purchase.

Rated 4 out of 5 by from Great Saddle I do get some chafing, but much improved with this saddle. It's very comfortable and I've been doing 20 mile rides.
