Top Best Triathlon Bikes for Beginners

In the world of bicycle racing, triathlon bikes are a different breed.  

Virtually synonymous with time trial bikes, or TT bikes, the geometry of triathlon bikes has distinct characteristics in frame design and rider positioning. These bikes typically have a steeper seat tube angle compared to that of road bikes, which puts athletes in a more aggressive and aerodynamic position. 

It’s also common for the saddle height on triathlon bikes to be positioned slightly higher. This promotes a horizontal, low-drag position while also widening the athlete’s hip angle.

Triathlon bikes are certainly beneficial for aerodynamics, but they also promote scientifically-supported1 biomechanical efficiencies that optimize running off the bike. More on that below.

 

2021 Triathlon Bikes from Entry-Level to Most Expensive 

Best Entry Level Triathlon Bikes for Beginners

The technology behind triathlon bikes is constantly evolving. Manufacturers continue to push the limits with research and development, making bikes lighter, faster, more aero, and more comfortable for triathletes. 

As a result, world records seem to be broken every couple of years. On the fastest Ironman courses, the best bike splits can exceed an average speed of 27 mph / 44 kmh. It’s also more common to witness sub-8-hour Ironman finishes – which are largely based on a fast and economical bike split.

One of the many beauties of triathlon is that beginner and amateur athletes have the same access to high-end bicycle technology as that of professional triathletes. 

We’ve compiled a comprehensive list of 2021 triathlon bikes that covers the full spectrum of performance and price point, whether you’re privy to entry-level tri bikes or top-tier technology. 

 

Entry-level Triathlon Bikes for Beginners

Entry Level TT Triathlon Bike Felt B 2021

Let’s be real. For many of us, the cost of buying a triathlon bike is not far from a full month’s income. While finding a used bike can be an economical option, new bikes can easily average $4,000-5,000+. Fortunately, there are several high-end tri bikes that come with more affordable price tags. Here’s a handful of them.

 

Felt B Triathlon Bike

Best Entry Level TT Triathlon Bike Felt B 2021Bikes like the Felt S32, B16, and B12 were among some of the original legends of the late 2000s. The B marque has long graced the entry-level model in Felt’s range of triathlon bikes, and at price ranges well under $3k (some even less than $2k).

Fast-forward to today and Felt is still producing bikes based on this legacy series, now simply known as “B”. It’s been updated in recent years to feature a full carbon frame set with aero shaping gleaned from the brand’s top-of-the-line and six-time Kona-winning IA collection.

Featuring classic rims brakes and a Shimano Ultegra group, the B is a great option for beginner and experienced triathletes, alike, providing terrific performance and value.

While B integrates aspects of the iconic B12 and B16 models, it also takes cues from Felt’s top-performance IA model, as well as the iconic DA frame kit. In other words, B is based on decades of aerodynamic innovation.

Unlike some tri bikes of today, Felt’s B maintains the integrity of a simple design but one that doesn’t compromise on performance. The aerodynamically-optimized downtube design and TeXtreme carbon technology make for a top-end bike at an unbeatable price. 

B’s designed around a carbon frame and fork and the bike weighs in at 20 lbs. It’s also equipped with Shimano Ultegra components and the capacity to convert to electronic shifting. 

The Felt B triathlon bike starts at $2,299, Feb 201.

More About Triathlon Bikes

As much as there is to learn about the different makes and models of triathlon bikes, there are still a lot of questions that arise. Below can earn more about the science and defining characteristics of triathlon bikes and common questions that often come up. 

What’s the Difference Between a Triathlon Bike and TT Bike?

The difference between triathlon bikes and time trial bikes is largely based on subtle differences in seat tube angle, fit, and whether the bike must adhere to the International Cycling Union (UCI) regulations. 

Keep in mind, triathlon bikes and TT bikes are so similar that they’re often treated as the same. In fact, some manufacturers offer a triathlon model and a TT model of the bike, just different build. 

Difference Between TT Time Trial Bike versus Triathlon Bike

UCI regulations defining time trial bikes are often considered the primary difference between triathlon bikes and TT bikes. A TT bike, which is made specifically for time trials versus multisport races, must have the tip of the saddle nose within 5cm/1.97inches from the center of the bottom bracket. 

Because triathlon bikes naturally have a steeper seat tube angle, thereby minimizing the saddle nose to bottom bracket distance, this rule is rarely a disadvantage or limitation.

 

What’s Special About Triathlon Bikes?

Based on the differences mentioned above, seat tube angle and fit are what make triathlon bike designs special. Like TT bikes, the geometry of triathlon bikes allows a larger seat tube angle. 

What's the Difference Between TT Bike vs Triathlon Bike Seat Tube Angle

As seat tube angle increases, this puts the cyclist in a position of less drag, greater aerodynamics, and wider hip angle.

An in-depth study1 that looked at several performance markers points to many reasons why TT and triathlon bikes have many benefits. The first and perhaps most obvious finding was that increasing seat tube angle positions the cyclist in a more forward inclination, thereby reducing drag and improving aerodynamics.

A more kinematic analysis of the study identified greater hip extension and ankle plantarflexion at a steeper seat tube angle. As the hip angle increases the length of bi-articulated muscles crossing the hip (Biceps Femoris, Rectus Femoris, Semitendinosus, and Semimembranosus), the level of output can be optimized for power and endurance.

Additional research2 on hip orientation suggests that increasing hip angle improves power from these muscles – widely known as the primary quads and hamstrings.

At a wider seat tube and hip angle, kinematic relationships in the force-velocity and length-tension of these powerful muscle groups are enhanced. 

Ultimately, TT bikes can yield biomechanical gains in power and efficiency, especially for triathlon. Further research3 has demonstrated that a steeper seat tube angle reduces fatigue associated with transitioning from cycling to running.

In summary, triathlon bikes not only improve aerodynamics, but they help optimize key muscle groups like the Biceps Femoris (or hamstrings) to enable more efficient running of the bike.

 

Why Do Triathlon Bikes Look Different?

As mentioned above, triathlon bikes have a steeper seat tube compared to road bikes. This widened angle opens the hips to sit forward which puts less tension on the cyclist quadriceps and hamstrings. This angle on triathlon bikes often exceeds 78 degrees, while on road bikes it’s more like 72 degrees.

In addition to a steeper seat tube angle, triathlon bikes often look different due to their unique frame designs. Triathlon bikes and time trial bikes typically have very narrow, thin, and tapered frames and forks.

what makes triathlon bike look different tt bike

This popular frame design seen in 2021 triathlon bikes delivers aerodynamic advantages that are magnified at higher speeds. Among these considerations is the yaw angle, which is is the angle between a rider’s direction of motion and the relative wind direction vector. The relative wind vector takes into account both the rider’s speed and the ambient wind direction, so higher speed TT/triathlon bikes can benefit from a very narrow, tapered frame design.
