The Specialized Phenom Comp is one of those rare mountain bike saddles that you put on your bike and never give a second thought. This saddle disappears beneath you and serves as a seamless interface between you and your machine. Comfort is one of its finest attributes, with a medium width and length, a nice tapered tail and a full-length anatomical channel to keep the pressure off your sensitive parts. Testers also loved the versatility of this saddle, as it can be used for virtually any type of cycling or length of ride. Our only gripe with the Phenom Comp is its weight, and it's really not all that heavy - but the one place where it lost ground to the competition. You know a saddle is excellent when the testing was over, and all of our reviewers wanted to keep it for themselves. Read on to find out more about our Editors' Choice Award winner.

Our Analysis and Test Results
We'd heard a lot of praise about the Specialized Phenom saddles in the past, but we reserved our judgment of the Phenom Comp until we'd put some rides on it. Turns out it lives up to the hype, and this saddle didn't disappoint on any level. The Phenom Comp was one of only a couple models that testers didn't want to take off their bikes, a saddle so comfortable and versatile that there was no good reason to stop using it. We loved the Phenom Comp so much that it took home our Editors' Choice Award; read on to find out why.
The Phenom Comp scored exceptionally well in our comfort rating metric. It tied for top honors with our Top Pick for Comfort Award winner, the WTB Koda Team. Both the Phenom Comp and the Koda Team were our most comfortable saddles, but they achieve this comfort in different ways.
The Phenom Comp uses Specialized's "Body Geometry" design, and one of the most comfortable and visible aspects of that is the full-length anatomical channel. When positioned in the optimal seated pedaling spot it works the best, but no matter where you find yourself on the saddle there is a depression in the center to reduce pressure on your most sensitive parts. The only other contender in our test selection with a similar cutout and channel is the Selle Italia Max SLR Gel.
The anatomical cutout of the Phenom Comp is full length on the top of the saddle, and there is a long narrow cutout in the center that is clear through the shell on the underside. The shell is made of a carbon reinforced plastic that is full coverage on the underside of the saddle. This shell offers a small amount of flex but provides a stout and stable platform; this is very different from the softer flex and suspended feel of the Tioga Spyder Outland
From tip to tail the Phenom Comp has a small amount of swoop in the middle with a slight rise towards the tail. When coupled with the limited amount of flex in the shell, this profile provides a nice and stable, yet surprisingly comfortable cradle for your bottom. There isn't much give to the whole system, and this makes for excellent and consistent power delivery when pedaling. The seat cover has a thin layer of medium density padding that offers just enough cushion to remain comfortable for extended periods in the saddle.
The side to side profile of the saddle is relatively rounded as it drops down to the sides. The Phenom Comp can be purchased in medium to wide widths, which cradle the sit bones nicely, while the anatomical cutout keeps pressure off the center of your business.
The Phenom Comp was the top performing saddle in our test selection, just edging out the WTB Volt Race in this metric. The extraordinary comfort of the Phenom Comp is one of the best aspects of its performance; on the trail, it virtually disappears beneath you so you can devote your focus to the trail ahead.
The shape of the saddle is where the performance begins, with a shorter 265mm length and a medium 143mm width. The short length is noticeable when you've got your weight centered and you're really getting the bike leaned over since the nose doesn't extend as far forward as come of the competition. Despite this saddle being on the wider side in our test selection, the rounded edges of the wings and the smooth seat cover material allow for excellent freedom of movement when shifting in front or behind it. It also tapers slightly from its widest point back to the tail with a flat end and nothing to snag your shorts or hang you up.
The Phenom Comp uses a medium density padding that was supportive and comfortable without feeling too soft. The combination of the stiffer shell and this padding proved to be comfortable for long days in the saddle, yet it felt efficient and didn't take away from power transfer or impact the pedal stroke. Specialized has also incorporated two small low friction panels along the sides of the nose of the nose to enhance pedaling efficiency. It's hard to say if the low friction material makes any difference, although it does feel slightly smoother and slipperier than the rest of the seat cover material.
The Phenom Comp scored well in our durability metric. The one-piece synthetic seat cover material has no visible stitching and is attached under the edge of the saddle's carbon reinforced shell. The seat cover material appears very durable and shows no signs of wear despite hundreds of miles of pedaling abuse. The entire back of the saddle is also ringed with this shell material as it curls up from underneath to protect this damage prone part of the saddle.
The saddle's rails show no signs of bending or wear, and despite many miles of riding and plenty of mud and water being splashed on them, they remain squeak free. The Phenom Comp was bested in this metric by the Tioga Spyder Outland due to that saddle's unique design and construction with no seat cover material to rip in the event of a crash.
The impressive comfort and performance of the Phenom Comp made this our highest scorer in the versatility department. Testers felt this saddle's comfort was great for any length of ride; our longest test ride was a 68-mile gravel grind, and for use on any kind of bike. Mountain, road, gravel, you name it, and this saddle is perfect for it.
Not only is comfortable, the saddle's shape and design also made it our top performer in the performance metric with a shorter 265mm length and a medium 143mm width. Testers found it easy to move on and off the saddle or get in front or behind it while out on the trail. This comfort combined with its performance made it great for any discipline or style of mountain biking, from all day vision quests to enduro racing. The Phenom Comp is up to the task.
The Phenom Comp weighed in at 243g, roughly middle of the pack in the weight metric. While this is by no means heavy, it is noticeably heavier than the lighter models in our test when held in your hand.
At 243g, the Phenom Comp weighs 41g more than our Top Pick for Light Weight Award winner, the Tioga Spyder Outland, and 40g more than our Top Pick for Comfort Award winner, the WTB Koda Team. Weight-conscious riders or racers may want to look elsewhere, as there are lighter weight versions of the Phenom available for a higher price.
Due to its excellent performance and versatility, it's hard to pigeonhole the Phenom Comp, and our testers found it to be great for absolutely everything. Any type of mountain biking, gravel, or road biking are right up this saddle's alley. The comfort and performance of this saddle are second to none and well suited to any cycling discipline. Gram counting racers may be slightly turned off by its weight, and that's fair, lighter weight versions of the Phenom are available.
At a retail price of $120, the Phenom Comp is a decent value. As our Editors' Choice Award winner, this saddle outperformed the competition and proved itself to be the best overall mountain bike saddle in our test. We believe a purchase of the Phenom Comp is money well spent.
It was awarded our Editors' Choice Award, so if it isn't all that obvious already, we really like this saddle. It's not the lightest model we tested, but it is very comfortable and provides excellent all-around performance. There is no type of cycling or length of ride we wouldn't take the Phenom Comp on. We loved this saddle, and we think you will too.
