The Best Aerobars in 2021, Tested and Rated

Our guide to four clip-on aerobars that’ll make you faster, more comfortable, and change with your changing tri body.

Get access to everything we publish when you sign up for Outside+.

One of the tell-tale signs that you are looking at a triathlon bike is a set of aerobars. These appendages allow riders to get into an aerodynamic position that – along with a proper bike fit – help riders maintain relative comfort for the duration of the bike leg. If you’ve never ridden with aerobars, you’re missing out. If your bike came with aerobars or you bought your aerobars a long time ago, it’s worth looking into the new breed of highly customizable, lightweight, and comfortable aerobars that’ll easily adjust, keep you out of the wind, and not add a ton of weight to your rig. The best aerobars today look a lot different than the best aerobars from even just ten years ago.

All of the models we looked at below are clip-on style, which means they can be used with almost any traditional road bike in addition to being mounted to a tri-specific bike. Each will also help you gain valuable speed in the discipline between the swim and the run.

We’ve put together a list of four of the most interesting sets of aerobars to help you find your best setup. Some may be looking to add aerobars to their road bike, some may be looking to upgrade what they’ve got to something lighter, more aggressive (or less aggressive), or something more comfortable.

Our easy-to-use guide includes ratings and info on criteria like value, ease of assembly, ease of adjustment, pad comfort, grip comfort, and more. We’ve also put together the specs to help you make your buying decision—fore/aft adjustment, armrest width, stack, extension shape, and more. Read on all of the info you need to make an educated decision on the best aerobars for you.

Editor’s Note: While the gear below was loaned out by the brands represented, all choices were selected independently by the tester without any promotional consideration or brand input. Also, unlike other “best aerobars review” websites, our testers actually install and try the gear ourselves—no glancing at spec sheets and rewording marketing terms!

The Zipp Vuka Clip with Alumina Evo Extensions is a great bar for athletes looking for a great all-around bar at a good price. With a wide range of adjustability, a competitive weight, and a price that won’t break the bank, it would be difficult to find another bar to match the value proposition that this bar offers. One of this bar’s highlights is the “evo” bend extensions that provide ample wrist relief, even after extended periods in the aero position.

Certainly some of the most lust-worthy bars we’ve come across, the ENVE Carbon Clip-On lives up to the company’s reputation for producing functional pieces of bicycle art. Unidirectional carbon fiber construction results in an exceptionally stiff bar. While the weight of the ENVE Clip-On is relatively low, the high price of these bars means the dollar-per-gram-saved ratio isn’t all that impressive. Adjustability is also somewhat lacking, however if the bars fit you as needed, a wide range of adjustability is unnecessary.

Vision Team Mini Clip-on | $162

Vision Team Mini Clip-on aerobars
Specs
Weight 443g
Armrest Fore/Aft Adjustment Only 15mm of fore/aft armrest adjustment
Armrest Width 30mm of lateral adjustment is possible with three rows of mounting holes to select from on each armrest cup. Adjustment is further limited but the extensions fixed-wide due to a bridge attaching the extensions to one another, a necessary design to make these bars legal for draft-legal racing.
Armrest Stack 40mm of stack from center of base bar to the top of the armrest pad
Extension Shape The single bend extensions are almost not even long enough to classify as ski-bend, given their purpose-built design focused for draft-legal racing.
Clamp Diameter 31.8mm

Vision’s Team Mini Clip-on is a bar on a mission: provide draft-legal triathletes with an aerobar that can help athletes get aero on the bike while conforming to the rules specified for draft-legal racing. Said rules likely limit the range of adjustability that is even possible, leading to the Mini Clip-on’s limited range. More sturdy hardware and a lower price could potentially improve this bar’s value proposition, but this bar might be one to consider if you’re looking for a compact design to give your road bike a bit more versatility when trying to get into an aero position.
