comfortable saddle for my older body
After struggling to find a comfortable saddle for my older body on my ebike, I happened onto this split saddle and gave it a try. It is working out well for me on my workouts on a paved trail. It is sleek enough that it does not get in the way, yet it fits well and does not hurt my butt on my typically hour-long rides.

Good rx
Great upgrade for a mountain bike seat. It's more comfortable than it looks in the images

SMART DESIGN, SOOTHING COMFORT, HIGH-END PERFORMANCE, GOOD BUY!
I'm 6'1"/158 lb. and I installed the Serfas RX-921V RX on my Trek SuperCommuter 8+ electric bike atop a Kinekt Suspension Seatpost. I always ride with padded bike short liners (Pearl Izumi Cargo Liner Short), for both the padding and to "smooth out" the riding surface. Sweaty cotton underwear creasing and bunching up between the butt-area and the saddle is a ride killer. I've never had particular saddle problems with any of my mountain or roads bikes before, but with the added weight of the ebike coming back at me while riding over imperfect roads and trails, I thought I'd give this Serfas saddle a shot to see what additional comfort I might obtain on my daily commute and longer rides. Frankly, I was amazed by how much MORE comfortable an already relatively comfortable ride became as a result of the Serfas saddle. The added cushion was a plus, but the functionality of the split saddle is where the real benefit was apparent. You can readily feel the independent support of the two saddle lobes. Riding the Serfas saddle also made me realize how I've come to take a certain amount of numbness and soreness for granted during longer rides. With the Serfas saddle I experienced a distinct and noticeable lack of numbness with no hint of soreness/nerve fatigue over rides of 30+ miles. The Serfas saddle renders the shorter, daily commuter miles all the more enjoyable. The Serfas is not a very expensive saddle as bicycle saddles go, which makes it worth more than every dollar spent. It just feels freakin' good!

Seems to be a better fit for women than the women's version.
Having worked for several years in a bike shop after retiring from another job, I have sold and have been a big fan of Serfas. They are not Selle Italia $$$ saddles of my Serotta, but for the money, many people find them very comfortable with very little break in. My daughters ride some pretty decent full carbon road and MT. bikes and with one exception still prefer their Serfas seats. I seems to me that the fitting of the Serfas has reversed and the longer wider women's version is now the men's and the shorter, narrower saddle is now sold as the women's, which anatomically speaking, makes no sense, so I had to return the women's saddle and purchase the men's RX Serfas for my daughter to gain the comfort she was looking for.

Best seat, just bought a second one
Hope do I like it? I just purchased another one for my second bike 4 months after first. —Great seat very comfortable !!! I used to ride centuries and a few doubles. Enough to scar a prostate :( . This seat is a super relief on middle section and no bike pants needed

Good for the money
I ride a lot , By a lot I mean, For fun, I road from Michigan to the bottom of Ohio into the appellation mountains . and to work and back a few times a week ( 30 miles each way ) This seat lasted about 1 month on my bike . Its a good seat , Comfy, easy on the man parts , and I did Not take it off because it broke or failed in any way . I just require something more suited to my particular bone structure ( Butt bones ) I log a lot of miles . If you are an average rider 5 to 10 mile rides . couple times a week, Then this is a nice seat , and most likely will be very comfortable . They are quality made and should last a few years with out to many issues. Good seat , worth a shot.
