I'm a big guy, 44yo, 5'10" and 230lbs. But I also ride my hybrid 28miles round trip to work five days a week. I needed a saddle that was comfortable to soak up the road and didn't compress the nether regions. Every saddle I have tried was either too narrow at the tail for my bum, didn't provide enough clearance to avoid compression or was too hard for longer rides. The Serfas RX is very comfortable with a great mix of padding and gel and most importantly the split design makes sure that nothing gets squished. If you're a road warrior with carbon everything this is not the saddle for you. It's too wide and too heavy. But if you're a modestly athletic middle age guy looking to stay in the saddle for a few more decades than you probably can't go wrong with this one. Some quick additional notes: - This saddle is about the split design, not performance, weight or even comfort (although I think it's quite good at soaking up the road). - It's not a terribly attractive saddle, but beauty is in the eye of the beholder...and I'll take a weird looking saddle over numbness. - I don't park my bike outdoors at either work or at home. Protection from the elements may have helped to keep the saddle in good shape. - Some people have asked me if the split design ever pinches. The answer is no. UPDATED 7/8/2013 I have 1.5 years of 5 day a week, all weather riding on this saddle and I have to say that it's far and away the best saddle I've owned. Since the original post my commute has increased to 35 round-trip miles daily and it's just as comfortable. First off, the build quality is impressive. Despite an approximate 13,000 miles of usage the only signs of wear are some fading of the black lycra fabric covering and the silk screened art has peeled a bit. There are zero popped stitches, fabric tears or signs of structural fatigue. I do think that the gel/padding are getting a bit tired but I only really notice that on bumpier sections of pavement. I have two other bikes with different saddles, one is a road bike and it has the stock saddle with only a shallow channel and the other is my weekend beater and it has an after-market super squishy granny seat. This Serfas RX is far and away my favorite. The only reason I haven't switched out the other two saddles is pure laziness on my part. UPDATED 8/22/2016 Still love this saddle enough that I finally bought a new one! Considering the abuse I put on my kit, I consider 5 years and ~30k miles a really good run. About 18mos ago I noticed that it lost some shock absorption. Not too extreme but on bigger jostles it felt like I was, pardon the pun, bottoming out. I didn't replace it right away, waited until last March, in hindsight I don't think I will wait next time. Still riding 5 days a week, although the last few winters took me off the road. I wasn't particularly cold, got good gear to keep me comfortable (I should probably write some reviews for those products as well!). However, my brake cables have frozen a few times. That's a bit scary. Anyway, 9 months a year I'm out there pedaling away! Other minor things... Most of the silk screen peeled away and there was definitely considerable fading of color. Interestingly, there weren't any popped stitches or rips in the lycra. Most importantly, so far the new saddle seems to be as well constructed as the original! Honestly, of all my bicycle accessory related purchases, this is one of the best decisions I've ever made.

I've now put 1500 miles on my fat tire E-bike using this seat and I can't believe how comfortable AND durable it is. I'm a very large guy, 6'-3" 300+ lbs, who rides almost every day a minimum of 9 miles, but often 20 miles or more. This seat is even more comfortable than using padded biking shorts on any other seat. It still has plenty of cushion after all the abuse it's taken from an XXL rider over many miles, often on rough terrain. I give this product my highest recommendation. It's so good that I doubt I would ever buy a bike seat from another company. It's a little more expensive than most of the other seats on Amazon but very much worth the price.

I ordered the Lycra but received the Microfiber (no complaints here). It's a huge improvement from my standard un-padded leather mountain bike saddle, which made me sore after only a few minutes of riding. Since installing this saddle, I've ridden several times for 30 minutes each without any soreness or numbness. I would've definitely experienced soreness and possibly numbness with my previous saddle after that amount of time. I'm confident this will be fine when I extend my trips to 1 hour (I'll provide an update if it doesn't). This saddle is about two inches wider on the rear portion than my original saddle. I was concerned with the size before purchasing since they also make a slim version for high performance riding, but this one doesn't seem to affect my performance. However, I'm not a racer, just a casual rider on mostly paved surfaces. I'm hoping that the microfiber is durable and lasts a long time. If not, the comfort is worth paying for another one. ** UPDATE ** After riding for about an hour and a half, I do feel some soreness the next day. It was definitely comfortable while riding but it's important to note that you can't expect to ride forever and not feel anything. I'm very happy that I didn't have any numbness during that entire ride, which is the most important aspect. The saddle didn't prevent me from continuing my ride if I wanted to, as it did with previous saddles. So I still highly recommend.

This is the 3rd one of these that I have purchased. First for my bike, then for my new bike, then for my wife's bike. Excellent comfort. Just make sure that you pay attention and make SMALL adjustments to it. Pay attention to the markings on the rails. try sliding backwards by 3-5mm, then ride it for a while. I had to take it off recently for a long drive to an out of town race. Put it back on once at my destination and missed the location by about 5mm... forgot my allen wrench during the ride, so had to make due... Play with the alignment... your rear will thank you! Oh yeah, if it begins to "creak"... take the seat off the bike, drop a couple of drops of 3N1 or Mystery Oil in the holes where the seat rails enter the seat frame... no more creaks/pops. Have almost 1000mi on the saddle on the new bike and it still looks brand new.

I use it on an exercise bike. I found that the Cloud 9 Cruiser Select Airflow ES was more comfortable.
