The best clip-on aerobars reviewed

Aero bars, also known as triathlon bars, are handlebar extensions with padded forearm rests that allow the rider to get into a more aero position by pulling their body forward into a position folded up, with a drooping torso.

Best Clip-On Sorting Bars

Zipp Vuka clip

Zipp’s Vuka Clip bars are available in aluminum or carbon – we tested the latest luxury version, weighing 218g per bar including the clamp. The standard 31.8mm clamp makes it suitable for use as a clipon with hanger bars, or on a tri rig complete with Zipp’s own Vuka Alumina base bar or Vuka Bull. Additional shims are included to increase the angle of the armrest up to 15 °, which you will appreciate if you prefer a “mantis” position. It also supports internal wiring to route the shifters if you intend to use it on a trike.

Installation is simple with two T25 bolts on each side to tighten the extension clamp to your drops, and two more T25 bolts on the top to tighten the bars to the clamp. There is a handy touch on the bars to dial the front / back of the extensions. Carbon assembly paste is included to prevent slipping between the clamp and the base bars you are setting up on. Zipp says the Vuka Clip was born from “data compiled from thousands of fitting sessions” to help riders maintain their aero stance for longer, and it shows just how ergonomic the extension is. The curvature and shape put the wrists in a very comfortable position, and coupled with the wide, dense pads, we felt like we could stay on the aerobars all day.

Verdict: expensive, but brilliantly ergonomic and a lot of settings offered 90%

Design Profile Sonic Ergo 45 / 25A

Profile Design’s Sonic Ergo is available with a number of different expansion options; the 45 / 25a here has an S-bend bar which curves upwards. We weighed each bar plus its clamp at 284g each, not much heavier than the Zipp carbon bars. Profile Design claims that it is “the most adjustable clip-on bar on the market”, with a large number of possible configurations thanks to the risers and 15 different positions for each armrest. There are also inserts for internal wiring.

Installation on your drops or base bars is very easy, with just a 5mm hex wrench needed to screw in the single top bolt and two on the underside to secure the clamp. The bars are 40cm long, which should be enough even for very tall riders who need a lot of reach, and there is a scale on the underside to mark the ideal bar length. We found the pads on the firm side, so not the most comfortable on a longer ride; we probably would have taped the extensions for something more than a sprint. While the Sonic Ergo costs significantly less than the Vuka Clip, it loses here due to poor comfort levels and standard round aluminum extensions, as well as the Vuka’s option to adjust the angle of the armrests with wedges. .

Verdict: a more basic set of clips with some noticeable extra features 80%

Bontrager Race X Lite

You would expect a set of clip-on bars with carbon extensions to be lightweight, and with a claimed weight of just 425g, this offering from Bontrager is substantially the lightest tested; and competitively priced, too. With measurements on the extensions helping you achieve the desired position, setting up the bars is simple, but a torque wrench is essential to combine alloy and carbon!

The ergonomically shaped ski arms start straight and have a little kick to get your hands resting at a comfortable angle, without having to twist your wrists too much, but those with larger hands may need to grip the end of the extension. The cushion stack height of just 43mm allows you to achieve a low profile and the position of the armrests is easy to change. Still, a small gripe is that in order to keep them from moving, you feel like you might be over-tightening the bolts.

Verdict: crisp and light bars, but the profile won’t fit all 82%

Vision Trimax Adj TT

The highly adjustable Trimax lives up to its name. With 40mm of lateral movement, you should be able to find a comfortable position for the armrests. If you’re a fan of a slammed stem, or like to hold the top of your handlebars when taking a break, you’ll appreciate the height offered by the Trimax’s stand and stacking spacers. Still, this support is quite substantial and contributes to the Trimax being the heaviest bar setup tested (claimed weight of 667g).

Once the stand and skates are installed, you slide the alloy ski arms out and secure them in place. Although tightening the extension bolts is a bit tricky, even when subjected to the recommended torque, they spin and the white decals don’t last long. The shallow J-bars really look out of the room and allow you to get a good stance, but for longer rides we would prefer thicker pads.

Verdict: A solid set of clip-on bars, but for £ 180 they’re 70% behind the competition

Profil Design T5 + Aerobar

Don’t worry about the relatively low price and simple appearance: Profile Design’s T5 + Aluminum are a reliable pair of aerodynamic hangers. Unlike the other bars tested, the supports for the armrest and extensions are independent, which means you can remove the pads from your handlebars and tilt them without affecting the angle of the ski arms.

The installation is very easy; all you need is a 5mm Allen wrench and a torque wrench. The extension cords have a classic appearance with a subtle 15º bend and, like other test bars, have ports for internal cable routing. But there are questions about the long-term durability of the pads, especially if they are used frequently indoors on the turbo, and, although they are tight, when driving over potholes. , the bars tended to move slightly.

Verdict: ignore the lack of glamor is a good option without breaking the bank 77%
