Best Triathlon Bikes for 2019 : Buyer’s Guide

When it comes to triathlons, there are no rules or specifications placed on what kind of bike you should use.  You are free to choose any bike that you would like to use.  Whether that means you decide to use a bike from the local store or a tricked out triathlon bike is completely up to you.  But it must be said quickly: triathlon bikes are by far the best choice.  These types of bikes are much faster than the typical ‘road’ bike that you see.  These bikes will help you push further toward your goals. 

Top Triathlon Bike Comparison Chart

Whether you are trying to top your personal best or win the race entirely, a good bike can put you over the top and give you a much better chance to accomplish what you set out to do.  In this buying guide, we’re going to take a look at the reasons you need a ‘tri’ bike, what makes them the best choice, and we’re going to help you select the best one possible with tips.  At the end of our guide, we will rank the top ten tri bikes that are for sale this year.

Triathlon Bike Buying Guide


The point of this article is to make you more informed about all things tri bikes.  But there are also some other things to consider before getting on too far.  For one, a tri bike is heavily encouraged for anyone that is going to be doing a triathlon.  However, it should be said that it is not always the answer for you.  Depending on the race type (we’ll look at that later) and the frequency of use, you may want to look at other options.

If you are going to be doing triathlon as a hobby in an inconsistent manner, it may not be worth it to you to buy a tri bike.  You might want to instead get a decent road bike and call it a day.  Sometimes this is just the better option, despite what anyone will tell you.  But if you’re ready to commit, then let’s look at some facts!

Another thing to look at is does the bike hold water bottles and how many does it hold?  How many you want and need depends totally on the length of the race and how much you want to drink.  You’ll have to make sure to find one that meets your needs, or you could be left disappointed!

Reasons to Get a Tri Bike

The most obvious reasons to purchase a tri bike is to help you gain speed in a triathlon.  Every second really does count, especially to those that compete in these types of events.  But who am I kidding?  You probably already know that!  No one likes to think that they are being slowed down by their equipment, so a tri bike can be the answer.  It’s also important to quickly say that a bike isn’t going to just magically make you better, either.  Practice and training is very much still a requirement.  So a tri bike is great because of its speed.  Now, let’s look at why it’s faster.

Aerodynamic Properties

Tri bikes are obviously built for speed, but knowing why is also very important to learn.  Tri bikes use aerodynamics to full effect in order to help you go faster.  Everything is streamlined on this type of bike to allow you to go as fast as possible.  This is a massive difference to what you will find with ordinary road bikes that you see everyday.  No matter how small, light, or good looking they are, they’ll still be slower simply because of aerodynamics.  The way that the frame is shaped allows the bike to be so much faster than what you would be able to do on a road bike.

For starters, the best tri bikes have a seat positioning that contrasts with that of a regular bike.  The seat tube, which is the place where your seat post sets into, is much more upright than a regular bike.  This will make you closer to the bike, and thus you’ll become more aerodynamic as a result.  In addition to the speed you gain, it also helps you be more efficient with your energy.  It literally saves your quads, a very important muscle for running, from being overused on this portion of the race, which will be a massive help to you as you run later on after the bike ride.  They do this by requiring you to use your hamstrings more in an effort to power yourself.  This is the case as you are much lower than you would be on the road bike.

The second big thing to notice is the handlebars on a tri bike.  In contrast to the regular road bike, they are positioned in a much different way.  Instead of being straight across, it is effectively in a U, or a bent shape.  This is done so that it can cut through the wind better, which also adds to aerodynamics.  It’s also made to help you be a little bit more comfortable as you’re going to be down lower than you would on a regular road bike!

Now, one thing that some people do is take a regular road bike and add ‘tri’ bars to it over time in an effort to slowly upgrade it.  This is always an option, just in case you are looking that way.


The components of a tri bike are just important as anything.  Components will determine how well your bike races and how well it holds up.  If you’re purchasing a bike, you’ll need to make sure that all of the parts and pieces are in decent quality.  You can get away with some of them being cheaper made, but there is a clear rule here.  The more cheaper components on it, the more likely it is to letting you down in the end.  That doesn’t mean that everyone needs to buy the most expensive bikes.  It just means that you need to aware of the fact that they are not all created the same.  This a generic term for any of the working parts of the bike.  These include the shifters, the brakes, the bearings, and even the pedals themselves.  These can make or break your day, and it’s important to take not when you see one that doesn’t look up to par.

The Frame

The frame of a tri bike is something that is very important to look at.  There are four main options that you can choose from.  Each has advantages and disadvantages that should be weighed carefully so you get the best possible bike for you.


Steel bikes are the most traditional of the frames on this list.  This bike was most popular way back in the 50s, and it’s held in high regard by old-timers and traditionalists alike.  The biggest asset that steel has is that is a great shock absorber.  This makes it incredibly comfortable on bumps and especially during the course of a long race.  The disadvantage of steel is that it’s seen as heavy.  Even though it’s sometimes just a couple of pounds heavier, some people just don’t want to be slowed down despite it’s comfort.


Aluminum bikes are the most commonly seen around.  The reason is that they are both light and they are naturally stiff.  This makes it great for coming out of corners as you can really accelerate very quickly indeed.  However, this kind of bike gives very little support for lighter riders over long races.  For people that are pretty heavy, it can be a really great option because you’re able to take the bumps much better.  The suggested cut off is around 175 lbs, so be aware of that as you consider an aluminum bike!


Titanium bikes have been a godsend to the top triathletes in the world.  This type of bike rides very similarly to a steel bike, but it is at less weight than steel.  This naturally makes it very desirable to all kinds of different riders.  It is able to absorb bumps, it’s quick off the corners, and titanium is very durable and will last a while.  Any guy or girl would feel great and be quicker on this bike, no matter their size or ability level.  But the drawback is definitely the price on this one.  It’s not because of the titanium itself, but it’s all to do with how they process the metal to make the bike.

Carbon Fiber

Carbon fiber is the bike for those that have bad backs and need a comfortable ride.  It is the most un stiff bike out, meaning it is the softest riding one you will likely find.  It has the best in shock absorption out there as well.  As you go on, however, this bike isn’t quite as good at preserving your energy as others would be.  Still a great choice for those that are lighter in weight or those that have injuries that want to take care of.


As you can see, comfort plays a large part in this process.  Without the correct fit, you are going to be left in a desperate state of affairs.  So it’s crucial to find something that fits YOU well.  It’s hard to find this with reviews online.  It’s great for general information to get you pointed in the right direction, but there’s nothing like trying out a bike just to make sure it fits you well.  Then, you can always go back to the online method to buy if you like.  This is something that is very crucial.  This is also dependent on how long races are in which you are competing and where exactly you are going to be doing it.

If you’re on a road that’s going to be bumpy and hilly, you’d naturally want a little bit different bike.  Some people will want something in between all of the variables so that they won’t have to worry no matter what kind, of course, they are set to face.  Just remember that the more ‘tri’ in the tri bike, the more unforgiving it will tend to be.  The speed is what you are looking for, and sometimes comfort will be thrown out the window.  But you must still find a degree of comfort unless you just want to grin and bare it for the entire journey.

Other Possible Options

There are some other options that you can find to give you more choices for choosing a tri bike.  These options have specific functions, and they could serve you well depending on what type of race you are in.  If you know you’re going to be doing a short sprint mostly, or a race on flat and straight road, you might want to consider what is called a time trial bike.  These are what you’d see Tour de France riders using in the last stage of the race.  Time trial bikes are even quicker than triathlon bikes, but they don’t offer as much comfort, shock absorption, or turn quite as well.  If you are going to be on mountains or rougher terrain, it’d be wise to avoid these for sure.

Best Triathlon Bike Reviews


Eagle T3 Carbon Fiber Triathlon Bike

Eagle is a company built by cyclists for cyclists.  Here is one high-end racing machine that will not disappoint.  The T3 is outfitted with insanely good components and workmanship.  It features carbon wheels, carbon handlebars and Shimano Ultegra Di2 electronic shifters and derailleurs.  Japanese (super-light) 700 series carbon fiber is the backbone of the frame, and it improves vibration damping.  This helps “damp” the vibrations caused by rough roads, so you’ll experience a bit more comfort over a long ride.  It does make a difference, but not as much of a difference as carbon fiber is sometimes touted to make.

We found lots of adjustments that help with proper ergonomics and comfort, like seat angle track, along with all the other stuff like seat post, handlebars, etc.  We found that the T3 is able to effectively ride the thin line between stiffness (which carbon offers) – which, on the one hand, is good for transferring power directly from your legs to the wheels, and, on the other hand, maintaining some level of comfort which comes with a “softer” frame which is not so stiff.


  • Great look
  • Comes in plenty of sizes
  • Excellent aerodynamics


  • Very expensive
  • Hard to upgrade



Kestrel Talon X Tri Shimano 105 Bike

Here’s a great option for those on a budget.  It’s not super cheap like $250, but it’s not priced like the Kestrel name would imply.  This is a high-end tri bike company offering an affordable option.  Kestrel makes the claim that this bike is the best combination of both road bike and time trial (aka “triathlon bike”) bike.  It combines the best of both worlds into one bike to save your wallet from the carnage resulting from the purchase of 2 different bikes to use for training and for competition.  It’s made of a patented EMH carbon (enhanced modulus hybrid) which is lightweight and stiff.  You’ll want the stiffness to properly transfer each pedal stroke into actual thrust power rather than being lost in the flex of a more malleable and less stiff frame.  You can even change the seatpost one way or the other to fit better for tri use or for road bike use.  There are many proprietary components on this bike, and that’s a big bonus!  Kestrel is one of the top triathlon bike companies in the world!

While not necessarily easy to put together, we determined that Kestrel has a winner in this model which is ESPECIALLY made for those just starting in the sport of Triathlon.  This is not the bike to use if you graduate to an elite level, but then, you’ll know that if you get there!  It is, however, the perfect bike for anyone more serious than a one time competitor, and less serious than a professional triathlete!


  • Unbelievable value for the price
  • Best option for beginners
  • Contains many options (including looks) found on bikes costing 3 times as much
  • Made by one of the world’s best-known names in Triathlon, or time trial bicycles


  • Not the absolute cheapest bike you can buy
  • Not made 100% for triathlons only (has road bike qualities though weighted for tri use)
  • Hard to assemble



Kestrel 5000 SL Ultegra Triathlon Road Bike

This legendary tri-bike maker has once again given us a winner for all triathletes.  The 5000 SL from Kestrel offers 800K high modulus carbon fiber construction (which happens to be the lightest carbon fiber Kestrel has ever used).  Aerodynamics are incorporated into nearly every single component on the bike, like handlebars, seat tube, seat post and stays.  All components are operated by a cable that runs totally inside the bike to ensure the best airflow possible for ultimate aerodynamics.

The 5000 is made mostly for competitive triathletes looking for the fastest bike Kestrel has ever made, and something with lots of adjustability.  However, the Shimano componentry is Ultegra which is meant to keep the already high price tag, as low as possible.  The highest-end Shimano components would be Dura-Ace, but that would jack the price too high for all but the wealthiest few athletes in the country.

As an FYI, Kestrel actually made the world’s first all carbon bike in 1987, and have led the pack in carbon technology ever since.


  • Good price
  • Protects back
  • Seat design is great


  • Wheels and tires are a little cheap
  • Requires a lot of assembly



Diamondback Serios S Ready Ride Bike

This bike from Diamondback is in the middle of our price range on the list.  It’s going to come packaged ready for you to nearly ride already!  In addition to quick assembly, it has a carbon frame to help you better protect your back and get around quicker.  The frame is especially great, but the components are lacking a little.  Overall, it’s a good mid to higher level tri bike.


  • Little assembly needed
  • Great frame
  • Carbon good for the back


  • A little pricey
  • Some components are little lacking



Stradalli Full Carbon Triathlon Bike

We included the Stradalli on our list for one reason, and it was absolutely not because of the big name or great reputation.  No, it has no great name or reputation!  What it does have, is VALUE!  Technically, it has construction and components that are equal to (Stradalli says “better than”) any big name competitor’s bike at twice the price!  Stradalli is proud to say it has no Tour De France advertising budget or big-name spokespeople or middlemen.  The savings are supposed to go straight to you.  Still, at $4000, this is no budget bike.

Having said that, $4K is a great price compared to something like the Kestrel 5000  eTap bike which is course, a phenomenal machine, but twice the price with componentry and construction that does not put the Stradalli to shame.  With 100% carbon fiber construction and black Ultegra 8000 Shimano componentry, this bike performs.  Carbon masks protect and cover anything that could cause extra wind drag like wires and front brake.  The rear brake is ingeniously mounted under the chainstay to keep it away from wind drag.

The geometry is as good as any higher-end bike, and Stradalli says it “meshes to the rider instead of making the rider mesh to the bike”.  The bike is very adjustable, and because of Stradalli’s linear size increments, this frame is suitable for riders of nearly any size (given the degree of adjustibility of all components).

We like this bike because of the value, though if we were friggin’ billionaires, we’d still buy the Kestrel!


  • Very well appointed with componentry and 100% carbon construction
  • Relatively comfortable
  • Good speed


  • Pricey
  • No big name or reputation to offer some degree of “comfort” and familiarity



Schwinn Men’s Axios TT 700C Bike

This is our first inexpensive bike on the list, and it comes from Schwinn, a company that’s very well known in the biking industry. We threw this one in as a wildcard!  It’s incredibly well-priced and for someone looking for a value-priced casual road bike, this is a good choice.  If you don’t plan on seriously competing in a triathlon, but just want to enter with some buddies from work for a fun Summer afternoon activity, this may fit the bill.  If you feel ambitious, you can fit the bike with aero components like a time trial handlebar, and you’ll look like you almost know what you’re doing!

This bike, like most at this price, is made from heavier aluminum.  The seat tube angle isn’t quite what triathletes are used to, but it’s still a good choice for beginners or people wanting a friendly option for their budget.  Components are obviously lower quality.


  • Great price
  • Aluminum is very comfortable for bigger riders
  • Good budget bike


  • Low-quality components
  • Seat tube is not tri-specific



Valdora PHX Carbon Fiber Triathlon Bike

Valdora is not exactly a household name, but like a few other “no-name” brands on our list, it’s a capable competition machine for any intermediate (and even elite level) triathlete.  Because it is made of carbon fiber, it places itself squarely in the “not-so-cheap” category, no matter the name!  Valdora has given much attention to geometry and proper ergonomics.  A bike may have good aero geometry, but if it’s uncomfortable, you won’t stay in the aero position very long – which defeats the whole purpose of having a time trial or triathlon bike in the first place.  Valdora has taken this issue into consideration.

The ride is stiff, but that could be said of most carbon bikes and in most cases, that is a very good thing!  Carbon has the least flexibility of all popular manufacturing materials used for bike frame building.  However, this frame only weighs 2.6 lbs.  That’s ridiculously light!  Even Triathlete Magazine couldn’t help comment on the PHX.  They said, “You’ll find that Valdora offers a light carbon compact that is every bit as much bike (and in some cases more) as is offered by the big boys, all the while leaving you less light in the wallet.”

There’s also a no-fault crash replacement warranty and limited lifetime warranty.


  • Really nice looks
  • Great price for what you get
  • Carbon helps you go faster


  • Not as cheap as the cheapest bike on the market
  • Hard to assemble
  • “no-name” brand



Conclusion & Recommendations

There are so many different choices to be made in this category because triathlons are very lax in regards to the biking stage.  There aren’t many rules beyond no drafting or blocking/hitting others, so you can be sure that many will have a tough time deciphering what they need.  Having a plan and knowing what you want is key.  Whether it’s for comfort, durability, or pure speed, there are plenty of choices out there. Remember that you must also get the right biking shoes if you want to ride at your highest level.  No matter if you’re budget is large or small, the right tri bike for you is out there, and it will help you go faster and feel better at the end of the day!
