The saddle needs of a triathlete, or someone embarking on a TT, are very different from those of a road cyclist. The forward position on a triathlete’s bike places increased pressure on the soft tissue and in slightly different areas. Additionally, the movement of the legs and hips is subtly altered.
Taking into account these factors, the best triathlon saddle has specific design features to maximize comfort, power, and aero profile. The fact is, that triathlon saddles are visually very different from road saddles. They undoubtedly have their own thing going on.
We’ve selected 5 triathlon saddles to represent a range of abilities and styles. Hopefully, there will be one in the mix that’s suitable for you.

Top 5 Best Triathlon Saddle In 2020 Reviews
1 ISM Pn3.1 Saddle
The ISM PN 3.1 is a tweaked version of the all-conquering PN 3.0. Thankfully, this classic triathlete truncated nosed design remains essentially unchanged. Yes, indeed, the good news is that the PN 3.1 nose-less saddle continues to offer both increased movement and comfort for the rider.
The width is 120mm at the rear. The length is just 255mm.
The saddle has stainless steel rails to help better bear your weight and, importantly, take some of the shocks of the road. The choice of stainless steel improves rider comfort, but it does add extra weight. If you’re looking for a super-light triathlon’s saddle, you might be disappointed with this one.
More positively, the saddle helps you to better rotate your hips. It also improves the clearance of your thighs and hamstrings. This is regardless of your position on the bike. Additionally, the nose-less design reduces pressure on your soft tissue in the genital area. This effectively reduces numbness and increases comfort over long rides.
The saddle is designed for triathletes who tuck on their aero bars and stay there. It’s not unusual for a triathlete to stay on the aero bars for most, if not all, of their ride.
The PN 3.1 has a little extra padding for riders looking for a slightly softer ride. It has 40mm of padding compared to the ISM PN 3.0, which has 30mm of padding. Although there is a slight weight penalty to the extra padding, this is still very much a performance saddle.
These kinds of saddles never look pretty. However, at least there is a choice of either black or white to hopefully match with your bike.
- 40mm padding.
- Facilitates hip rotation.
- Reduces pressure on soft tissue.
- Shock absorbing rail.
2 PRO Aerofuel Carbon Triathlon Bicycle Saddle
If you’re looking for a traditional short-nosed saddle and also want to keep the weight nice and low, this is a great option. This short carbon-railed saddle weighs just 175gms. This gives it a significant weight advantage over most ISM and similarly truncated saddles.
The saddle is 265mm long and is 142mm wide. It’s quite wide at the rear. Now we get that most triathletes will spend most of their time at the front of the saddle. However, for riders with wider sit bones, who may more frequently stray to the rear of the saddle, this might prove more comfortable.
The Pro Aerofuel saddle has EVA padding, which is enough to give some relief, but not too much to get in the way of your thighs and legs. The top of the saddle also has a non-slip coating. This is perfect for stopping you from sliding around once you’re into your tuck.
The center of the saddle has a cutaway to give some soft tissue relief. We’re sure you’ll all agree, an absolute must-have feature for a triathlete’s saddle. Honestly, it’s also pretty much a must-have for most road cyclists too.
The saddle is a good choice for triathletes who don’t find split saddles comfortable. The more traditional shape of the saddle also makes it suitable for use on road bikes.
For those of you that don’t like black saddles, there are red and white colorways for you to choose from.
- Cutaway channel.
- It’s wide at the rear.
- Good balance of EVA padding.
3 ISM PN 1.1 Saddle
This is a narrow saddle from the ISM range.
It has all the good stuff you expect from an ISM saddle. It’s a nose-less and short saddle. Furthermore, the channel running through the center of the saddle provides excellent relief for a rider’s soft tissue. Consequently, you can ride for extended periods without the fear of suffering numbness in your undercarriage.
For ladies competing in triathlons, the ISM PN1.1 will afford most of the same advantages experienced by men. Namely, the same ease and transmission of power. Plus, they will also get soft tissue relief, though of course of a different nature.
The short narrow arms on the PN 1.1 allow you to get a more forward position on the bike. This allows you to get in the aero tuck and put through more power through the pedals. You’re able to do this whilst freeing up your hips.
The saddle has steel rails which help to improve shock absorption. Something that is very welcome on more arduous and extended rides. Sadly, you will have to pay a weight penalty. The ISM PN 1.1 pushes up towards 400gms, which is quite honestly a lot.
The ISM PN 1.1 is longer and thinner in comparison to the PN 3.1.
The saddle measures 270mm long and just 110mm wide. That’s pretty narrow. The padding is exactly the same as the PN 3.1 and measures 40mm thick.
This extra narrow saddle has a distinctive PN 1.1 logo proudly emblazoned on the top. It looks pretty cool. If you don’t like the black version, there is a white alternative available.
- Good padding.
- Facilitates hip rotation.
- Steel rails.
- Soft tissue relief channel.
- Might be too narrow for some.
4 ISM PR 3.0 Saddle 235mm x 145mm
This shouldn’t be confused with either the ISM PN 3.0 or any other ISM PN range. Though the saddle does share a lot of the design fundamentals, there are some significant differences. The length, width, and padding are the obvious points of divergence, so let’s take a look at those first.
It measures 145mm at its widest part. Compared to the ISM PN 3.1 and ISM PN 1.1 that is 120mm and 110mm respectively, the ISM PR 3.0 is a bit of a wide boy.
As well as being wider, the saddle also has a lot of padding 60mm to be exact. This again is significantly different from the ISM PN range that max out at 40mm of padding.
Wide seats and thick padding on a triathlete’s bike, or indeed on a road bike, are not a common sight. This kind of padding, though admittedly usually a little thicker, is more commonly found on city bikes, cruisers or hybrids. It’s found on bikes where the rider spends a large amount of time in more of an upright position with their weight on their posterior.
Firstly, since it is relatively short at just 22cms, and has a nose-less design. It’s great in helping all riders to increase their hip rotation, plus reduce pressure on their soft tissues.
Secondly, the extra padding and increased width can help to increase the comfort of a triathlete who may be unable to hold a TT position for long periods. It allows the athlete to move back and get some respite from the tuck. Not all of us are young or flexible enough to hold the tuck for hours.
As it turns out, it’s also a nice compromise for a broader range of cyclists. This ISM PR 3.0 is also suitable for road cyclists and leisure cyclists who want to free up leg movement and increase relief to their undercarriage. This saddle isn’t all about triathlons and triathletes.
After saying that, for the right riders, it’s still a great triathlete’s performance saddle. The fact is, with its rear transition hook, there can be no doubt that the PR 3.0 is still very focused on the triathlete market.
- Very wide.
- 60mm gel padding.
- Transition hook.
- Ensures good hip rotation.
- Not suitable for more aggressive riders.
5 Transiro Mistica k:ium
This is a Fizik saddle.
Fizik is better known for their road saddles. Any review of the best road saddles will always have one or two Fizik saddles included. The quality and attention to detail of their saddles are exceptional. Fizik produces high-end saddles that are popular choices for professionals and serious amateurs alike.
Happily, they also make triathlon saddles.
Yes. That was easy!
There’s no mistake that this is a well-made quality saddle. It’s also been designed with triathletes and TT riders very much in mind. It’s short with a stubby nose, though like the Pro Aerofuel, it’s not nose-less, unlike all ISM saddles. However, there is still a channel running down the center of the saddle for soft tissue relief.
Other design features specifically for TT and triathletes include the transition hook and mount. The mount is there to allow the athlete to attach bottle cages for those doing long time trails or rides.
The Transiro Mistica k:ium is very similar in design to the Fizik Arione. Except for the cut off nose. So, if you get on well with the one, you’ll very likely get on with the other. Like the Arione, the Transiro Mistica k:ium also comes in different widths, large and medium, to cater for people with different size sit bones.
It has a carbon rail which helps to keeps its weight down to just 205gms. This is a premium saddle; you will, therefore, expect to pay a premium price for.
If, however, the price is just a little too rich for your blood, you should check out the titanium rail version. It also has the same design features and quality but at a more affordable price. There will, however, be a 30gms weight penalty to pay.
The saddle should be every bit as comfortable for aggressive and flexible riders as an ISM saddle. It’s a great alternative to a nose-less saddle.
- Beautifully made.
- Medium and large widths available.
- Rear removable/integrated bottle cage.
- No full cutaway relief channel.
Best Triathlon Saddle Buying Guide
Getting into an aero tuck and maintaining the position over an extended period places very different stresses on triathletes compared to their road bike riding brothers and sisters. Riding in a forward tucked position requires a specific forward pelvic tilt. This, in turn, places high levels of pressure on the soft tissue and pelvic area.
The ideal triathlon saddle design is, therefore, one that can help you to facilitate power transfer in the power tuck. Plus, give relief to your soft tissue. Enter the triathlete specific saddle.
Having thicker padding doesn’t necessarily correspond to increased comfort. Often, usually on performance saddles, it’s the exact opposite.
Heavy padding is most effective when the rider is sitting in an upright position and putting most of their weight through the saddle. This is commonly the position adopted on cruisers, city, and hybrid bikes. This is why these saddles are frequently heavily padded and even sprung.
On a road bike, triathlete’s bike, or a TT bike, most of the weight, pressure, and force will go through the pedals. This means less padding is required. In fact, more padding can be a hindrance. This is because more padding can, and usually will, cause chafing over long distances.
The simple equation is that the more powerful the rider and the more aggressive position adopted, the less padding is required. With a forwardly placed saddle position, 30mm of padding is usually more than sufficient.
Wider saddles on a triathlon saddle are for athletes with larger sit bones and also for athletes who may spend some time at the rear of the saddle. Everything we said about the level of padding mostly holds true for the width.
Strong triathletes spend more time in a tucked position at the front of the saddle, so require less width at the rear. For triathletes looking to spend more of their ride in an aero tuck, either the ISM PN 3.1 or 1.1 would be a great choice.
Less flexible and less powerful athletes would be more suited to the much wider Fizuk Transiro Mistica k:ium or PRO Aerofuel Carbon Triathlon saddles.
Nose-less & Cutaway Saddles
ISM was one of the first companies to bring a nose-less saddle to the market. The advantage of the nose-less saddle is that it gives the rider a larger area for soft tissue relief. This reduces numbness and improves comfort.
As we discussed in the overview section, a triathlon saddle is designed to alleviate discomfort, with the specific triathlete’s aero tuck position firmly in mind.
However, not everyone can get comfortable on a nose-less saddle. If this is the case, then both the Pro Aerofuel and the Fizik Transiro Mistica k:ium offer good alternatives.
Two nice accessories to have for a triathlete’s saddle are a transition bar and an extra mount for an additional water bottle cage. The transition bar is used to hang your bike in the transition area before the run. The extra mount is useful for extra-long stages to enable you to carry extra water.
We think the Fizik Transiro Mistica k:ium is the best-accessorized triathlon saddle. This is because it was the only saddle in our review to have both a transition bar and an integrated but removable mount.

Final Thoughts on The Best Triathlon Saddle
So, there you have it — a selection of five triathlon saddles that should hopefully cover the needs of most triathletes.
At the best of times, saddle selection is a very personal process. It can be difficult to get the choice correct the first time. If you can borrow a friend’s saddle first to try, that’s always a good idea. If not, then you need to be honest with yourself about your ability and style. Then, fingers crossed, you’ll get it right the first time.
We truly hope so.
Of the saddles we reviewed today, our top pick is the…ISM PN 3.1
It represents a happy medium of the options available. It has a good amount of padding though not too much and not too little. It’s not the widest or, then again, the narrowest.
However, most importantly, it has that classic nose-less triathlon saddle design to optimize soft tissue relief. Its stubby nose also facilitates hip rotation, and the steel rails add a bit of extra shock-absorbing comfort.
The ISM PN 3.1 is every inch a quality classic triathlete’s saddle.
Here’s to better comfort on your rides.
