Additionally, its noseless design provides soft tissue relief and maximizes blood flow so the triathlete isn’t just comfortable but also physically at their best.

2. Fizik Transiro Mystica Kium

The Transiro Mystica is one of our favorites because of how easy it makes staying in the aero tuck position. One of the main reasons for this is the inclusion of Kium alloy rails which are lightweight without compromising on strength. Not only do these promote the perfect aero riding position, but they ensure that the triathlete has plenty of support during their ride.

We’ve named this product one of the best triathlon bike saddles for another important reason – the comfort it provides. For triathletes who are sick of chafing and friction, this is a godsend. The Transiro Mystica’s clever design includes a channel that allows for better weight distribution across the sit bones. Because it’s nosefree, this saddle provides soft tissue relief and makes sure that the triathlete doesn’t face any issues when it comes to numbness or other types of discomfort.

Additionally, this triathlon bike saddle prioritizes stability by using an extremely grippy material in its construction. If they opt for this saddle, triathletes no longer have to worry about slippage ruining their concentration.

The sturdy construction is another reason to love this triathlon bike saddle. The carbon-reinforced nylon shell ensures that the saddle will last for years to come, making it a sound investment. Besides this, it includes a redesigned carriage that increases versatility and makes the saddle easy to install. Whether you’re a seasoned professional or a beginner, you’ll have no problem with this saddle. The saddle is also compatible with an integrated clip system.

3. PRO Shimano Aerofuel Carbon Saddle

One of the Shimano Aerofuel’s most impressive features is its inclusion of carbon rails for such an affordable price. Not only does the carbon construction make the saddle lighter, but it also makes the saddle supportive and durable.

To make sure that the triathlete is comfortable, the saddle’s design includes a broad anatomic recess area to provide plenty of support throughout the journey. This is especially useful when it comes to longer races like the Ironman. The lightweight EVA padding also increases comfort as does the accompanying anti-slip cover to keep the triathlete stable at all times.

Even the base of the saddle is made to last and is constructed from a carbon-reinforced polymer. Triathletes who invest in this saddle will be sure to use it for years to come. An added advantage is how short the base is, and this allows the triathlete to sit forward and maintain an aero position while remaining comfortable.


  • Relatively affordable
  • Anti-slip cover
  • Durable carbon construction
  • EVA padding for comfort
  • Supportive rails and base



Features to Consider When Buying a Bike Saddle for Triathlons

Triathlon bike saddles are completely different from those used in road bikes. To minimize time and maximize comfort, make sure to keep the following factors in mind when making your decision.


While most people think that thicker padding will provide more comfort, this isn’t the case for triathlon bike saddles. Because triathletes have to maintain an aerodynamic position, they do not put their weight on the saddle and thick padding isn’t required. In fact, for optimized performance, you should look for less padding – 30 mm of padding is more than enough.


More important than thick padding is the shape of the saddle. Of course, this is largely dependent on a triathlete’s riding style. Riders who sit lower prefer flatter saddles; however, those who sit a little more upright prefer wider, curved saddles.


Rails support the saddle and can be a determining factor in price. Different materials offer different advantages. While steel rails are common and inexpensive, materials like titanium and carbon are pricier, because they’re lighter and more forgiving. They’re also more comfortable than steel rails.

Sit Bone Width

Because triathletes are positioned at the front of the saddle, too much width at the end isn’t required. However, if you truly require a custom fit, specialty shops can measure your sit bones and provide the best option for your unique measurements.


Noseless saddles are an excellent choice for triathletes who suffer from numbness on long rides. They also provide plenty of comfort and allow triathletes to maintain their aero position. Cutouts can also help alleviate discomfort by providing soft tissue relief and promoting airflow.

Additional Features

Additional features such as transition bars and extra mounts can be extremely helpful during triathlons. However, these are not necessary.
