Maximize aero gains by choosing the right bar set up

Since taking up triathlon, you’ve probably asked yourself at some point whether you should be riding a road bike with add clip-on bars, or go all in with a triathlon bike.

Both options can improve aerodynamics, speed, and efficiency, but they come with different costs, handling skills, and confidence levels. Depending on one’s experience, goals, and bank balance, the answer is different for everyone.

Going with clip-ons

Clip-on aero bars are attachable extensions that mount onto the handlebars of a road bike, allowing you to adopt a more aerodynamic position without buying a dedicated triathlon bike.

They’re affordable at a fraction of the cost of a triathlon bike. You can generally get a pair for anywhere from $100 to $500 dollars, compared to a shiny new triathlon bike that could set you back thousands. Clip-ons are also versatile as they can be removed when not in use, so your road bike can still be used for group rides and climbing. Most clip-ons are fairly easy to install and fit standard handlebars and require minimal adjustment.

The drawbacks to going with clip-ons include compromising on aerodynamics as the geometry of a road bike isn’t as aerodynamic as a road bike. With a triathlon bike comes the added aerodynamic advantage of a bike designed to go faster than a roadie. Though you will be down in the bars with clip-ons, and improve aerodynamics over sitting up or in the drops, it still isn’t as optimal as a triathlon bike.

A lack of handling and comfort is also something you will have to compromise on with a road bike and clip-ons, as the bike is not designed to hold the aero position with the same level of integration as a triathlon bike. Clip-ons are also limited in their adjustability, so it is harder to dial in the best aerodynamic position that also provides comfort and optimal power transfer for long hours in the saddle. Anyone preferring to ride a road bike can still get aerodynamic advantages with clip-ons.

Going all in with a triathlon bike

A triathlon bike is a purpose-built machine designed for aerodynamic efficiency, power transfer, and speed in non-drafting races. It has a unique aero geometry due to its steeper seat tube angle, which is for better power output. Because the aero bars are integrated into the geometry of the bike, the rider will enjoy better comfort and positioning. Most triathlon bikes are also tested in wind-tunnels and proven to cut through the air with minimal resistance.

Road bikes, on the other hand, are more focused on handling and climbing, with a more relaxed geometry.

If you go all in with a triathlon bike you will get maximum aerodynamics  because every part of the bike is optimized for speed in time trials. The design also offers better power transfer because it encourages a forward positioning, improving efficiency. Built-on aero bars are adjustable so they can be personalized to ensure comfort in an aggressive position.

The flip-side to going all in is expense. A carbon triathlon bike can set you back anywhere from a couple thousand dollars to well over $15,000. They are also a style of bike designed for a very specific function – speed, and so are less versatile than a road bike. They also tend to be heavier in their pursuit of aerodynamics, so they are less effective on climbs than a lighter road bike built for that very purpose.

The right fit for you

It’s a personal decision based on a multitude of factors, but some things to consider when weighing your options can help simplify the choice.

Clip-ons work well for athletes who are new to triathlon and want a budget-friendly aero setup. They are also the ideal choice for anyone who prefers a more versatile bike that is good for multiple uses. Athletes racing short-course also have the added bonus that their bike will always be legal, as some sprints and standard distances races are not draft-legal. There is also a diminishing return on the benefits of aerodynamics in contrast to the other tradeoffs as the race distances get shorter.

A triathlon bike is the solid choice for anyone who plans to be in the sport for a long time and will be racing the longer distances, in which comfort and aerodynamics go a long way. The customization options with a triathlon bike are also an advantage and the importance of this increases as race distances increase.

The verdict

For beginners and budget-conscious athletes, clip-on aero bars are a great way to get aero benefits without the huge investment. However, if you’re concerned about performance, investing in a triathlon bike will give you the best speed, efficiency, and comfort for long-course racing.
