Clip-On Aerobars Reviews and How-To

Sometimes, you have a road bike you love to ride, but want to be able to get more aerodynamic in the tuck position. Or perhaps you just don’t have the budget to upgrade your road bike to a true time trial bike.  That is where clip-on aerobars come in.

Clip-on aerobars are easy-to-install and functional.  While they won’t technically turn your road bike into a tri bike (more on that later), they can improve your comfort, performance, and riding speed without having to spend thousands of dollars on the greatest triathlon bike. In this article, we’ll analyze the top five clip-on aero bars out there and tell you how to choose the aero bars that best suit your needs.

Top 5 Clip-On Aerobars

Since there are plenty of great products on the market, we’ve compiled a list of the top five clip-on aero bars that any cyclist may use on their beloved road bike.  Spoiler alert: Two companies have the aerobar market cornered.

Profile Design T2+ Clip-On Aerobars

Best Budget Choice.

Profile Designs has been a big name — perhaps the biggest — in aerobars for a decade or more.  We like that they make bars for a wide range of budgets, and the T2 is budget-friendly if you need to keep a lid on costs (as long as you don’t get the carbon version of the T2).

The Profile Designs T2+ Clip-On Aerobars (here on Amazon) have a subtle S-bend that helps your hands stay low and “aggressive” as well as enjoying the enhanced comfort provided by the height difference between the armrests and the extensions’ end. The S-bend is similar to how skiers are holding their poles when fully tucked: this means that your wrists will be bend and your hands will be tilted down.

Made of 6061 aluminum and mated to the same hardware and clamps found on the T1 aero bars, these S-bend extensions are among the most popular on the market. The handlebar clamps are nicely tightened to the bars, separately from the extensions and the armrests. Hence, you’ll be able to determine the appropriate width first and then set the extensions’ length and the armrests’ angle. Moreover, the fact that the armrest clamp is round on a round tube gives you the ability to adjust the armrests’ cant. Correspondingly, this allows you to have the armrests tilted outward or inward, which provides a secure feeling if you like a narrow position. Plus, it offers some height adjustment. If you’re a fan of a wide position, it’s recommended that you lower the armrests and carefully tilt them outward.

Also known as J2 Brackets, the armrest clamps can be moved fore and aft right on the extensions, allowing you to set the armrests at three different fore/aft positions, two widths, and to adjust the rests’ angle.

The reviews mention that the product is easy to install and adjust, extremely comfortable, and working perfectly. Users recommend the Profile Designs T2+ Clip-On Aerobars for long rides since they’re high-quality and really durable.  Find Here On Amazon.

Profile Designs Sonic Ergo 35a Clip-On Aerobars

The Profile Designs Sonic Ergo 35a Clip-On Aerobars (here on Amazon) are, undoubtedly, one of the brand’s highlights. Thanks to its Ergo armrests, the Sonic bracket allows a sheer range of adjustment options. The armrest was designed to offer both an enhanced rider comfort with a nice, supportive curve that cups the arms, as well as a great upgrade in fit range.

When it comes to performance, the Profile Designs Sonic Ergo 35a Clip-On Aerobars are crafted to present minimal frontal area in order to create as little aerodynamic drag as possible. Despite its fairly minimalist look, the aero bar offers a comprehensive fit range to get the rider into a fast position.

Both extension length and rotation can be effortlessly adjusted simply by using the top bolt. Just by moving the armrests, you can achieve 100 different position options.  If you combine that with the risers, you’ll realize that this clip-on bar offers an impressive 1500 possible configurations. Plus, you can easily adjust the extension tilt and width, which makes it one of the most adjustable products of its kind on the market. Actually, its adjustability makes it highly appreciated among riders.  Find Here On Amazon.

Profile Designs T4+ Carbon Clip-On Aerobars

Top Choice Overall.

With the Profile Designs T4+ Carbon Clip-On Aerobars, you can easily and quickly dial in the perfect time trial position. Featuring a traditional ski-bend shape with a rather shallow angle between the shifters and the extension, the product facilitates optimal aerodynamics by offering a neutral wrist angle with a low extension height.

The Profile Designs T4+ Carbon Clip-On Aerobars include a J4 bracket which is carefully controlled by one single bolt, allowing you to effortlessly adjust the rotations and extension length. The F-35 armrests that complete the T4 bars feature 3x fore/aft positioning. Moreover, the F-35 allows for 30mm of adjustment and offers approximately 15 degrees of rotation adjustment. Thus, you will never struggle to find the perfect fit. Another thing well-worth mentioning is that these aero bars are compatible with 26.0mm as well as 31.8mm bars.

The vast majority of the people who reviewed this product said it’s top-notch, easy to install, making a big difference in effort, and very comfortable on the wrists. The Profile Designs T4+ Carbon Clip-On Aerobars helped users enjoy long rides. Users also appreciate that the aero bars are lightweight and have plenty of adjustments.  Find Here On Amazon.

Vision Team Alloy Clip-On Aero Bars

Weighing only 464 grams, these aero bars are lightweight — most aerobars weigh-in at 600 grams or more. Yet strong thanks to their aluminum construction which will make your cockpit aerodynamic without emptying your pockets. The Vision Team Alloy Clip-On Aero Bars are made from alloy, bead blasted anodized black, have a diameter of 31.8mm and an extension length of 40mm. The bars extension adjustment is fixed, making them adjustable from 230mm to 270mm. The low-profile armrest pads and J-bed design ensure an ergonomic, fast, and comfy position.

According to the user reviews, the Vision Team Alloy Clip-On Aero Bars, helped riders’ time improve, which eventually increased their desire of getting better. Those who’ve purchased the product appreciate the secured armrests and the state-of-the-art alloy construction. Some people were, however, unsatisfied by the limited extension adjustment.

Vision is a neat company that has been around since the 90s.  Founded in Kona, Hawaii, they focus exclusively on aerodynamic bike parts. We like companies that pick a niche and stick with it.  Find Here On Amazon.

Vision Team Mini TT Clip-Ons Aero Bar

Compact yet highly performant, the UCI-compliant Vision Team Mini TT Clip-Ons Aero Bar offers a nice aero riding position. It has a lovely, minimalist CFD refined design with a black anodized and white graphics finish. Its 170mm fixed-length butted aluminum extensions join right at their forward end by a UCI adaptable 3:1 aerobridge. As they’re adjustable, the ergonomic armrests allow you to fine-tine your riding position. Not to mention that the Vision Team Mini TT Clip-Ons Aero Bar features molded armrest pads which are comfortable even on long rides.

Most riders say that the product is well constructed and really easy to install.  The arm pads are also notably comfortable, compared to others in the price range. And when you are in the middle of a 70-mile ride, arm pad comfort matters.  Find Here On Amazon.

What to Look For in Clip-on Aero Bars?

If you’re a total newbie, meaning that you’ve never ridden with clip-on aero bars before, it will probably be best to opt for something affordable, such as steel or aluminum. This way, you can get a relevant feel for the device and its advantages.

If you prefer riding with a carbon bike, you’ll certainly love carbon aero bars, as well. However, keep in mind that the two pieces are not always necessary together. Many believe that carbon can help smoothen some of the vibrations you experience when competing in triathlons with some potential road shock or rocky areas. Nevertheless, some experts think that a state-of-the-art pair of aero bar pads can do the exact same thing for way cheaper.  The weight difference might be negligible.

The other thing you will want to determine is your preferred design.  Some bars have the J-Bend, which means the bars rise up at the end like the bottom of a J.  They are also called a ski-bend because they look like the tips of skis.  Others are the S-Bend, which means that they rise up a bit but then straighten out again.  It really is personal preference on which you will like.  With that said, the Complete Tri staff is partial to the S-bend for comfort reasons.

The rule of thumb when shopping for clip-on aero pads is to go for comfortable, lightweight, top-notch models. Aero bars made by top manufacturers like Profile Design, Vision Tech, and Zipp usually offer all these features.

Thanks to their numerous benefits, aero bars are, nowadays, used by everyday cyclists through to professional athletes. There are a bunch of products available online and in physical stores, so deciding which one is the best for you might be a bit challenging. Knowing that, we created this mini-guide, which is meant to make it easier for you to choose the best clip-on aero bars for your riding needs.

Will Aerobars Turn My Bike into a Tri Bike?


Aerobars will help you get down in aero position, no doubt, which can help your aerodynamics. They are especially useful on a long straightaway, allowing you to be in a comfortable position as you crank for speed.  They can’t transform your bike geometry, though.

A tri bike and a road bike have different frame geometry.  A tri bike has steeper, more upright angles, allowing the rider to really get into a nice groove on a flat, and allowing the rider to have fresher legs on the run because of the way the geometry engages the quads and hamstrings.

A road bike has more relaxed geometry, which is actually useful on hills and curves where you want responsiveness, and is more comfortable when not exerting at 110%.  But a road bike geometry will cause your legs to often be more fatigued as you start the run.

The aerobars will help you be able to settle in to aero position, and many riders feel that aerobars are a more comfortable option versus being down in the drops on your handlebars.  But we want to make sure people know that there are other differences between road bikes and tri bikes than the bars.

Do Aerobars Have a Shifter and Brakes?

Shifter, maybe.  Brakes, no.

Aerobars are designed to either be simply a bolt-on piece with no components, but in many cases the shift function can be extended through the aerobar to put shifter at your fingertips while in aero position. We prefer this, as it seems easier to reach for the end of the aerobar at any time than to come up out of a tuck position just to shift. It is a one or the other type of thing, though. The shift will either be on your handlebars or your aerobars, not both.  If you go the route of self-installation and want to setup your shifters on your aerobars, take your time and learn how to do it according to the specs — or take it to a shop. Getting your shifting right is a safety consideration when you are on the road.

Brake levers are not added to aerobars. Brakes will remain mounted where there originally were on your bike, likely mounted on your handlebar under some sort of brake hood.  They should stay there.

How do I Put Aerobars on My Bike?

We will leave that one to the instructions that come with your specific bars, because every set is going to be a little different.  The good news is that it is not difficult to put them on, you just need to have a few of the right tools and perhaps 30 minutes so you are not rushed, and can do a quality job.

Given the delicate materials you will be working with on both the aerobars and your bike, you absolutely do not want to overtighten the screws.  You could break something expensive. This is most certainly a job for a good bike torque wrench (like this one).  If you don’t own one yet, perhaps now is the time to get one.
