At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Easton EC70 Aero Handlebar is light, stiff and offers plenty of comfortable hand positions. Internal cable routing keeps things looking clean, and it's easy to set up too. It doesn't come cheap, though.

The EC70 is a good looking handlebar, with its flat top section having a more rounded profile to it than most, which gets rid of any 'edges' where your palms and fingers sit; this greatly improves comfort, similar to that of a traditional rounded bar.

I ride on the tops a lot, and while that flat section is primarily there for aerodynamic marginal gains, it does give a supportive place to rest your hands.

In fact, it's relatively comfortable overall for such a stiff bar.

Its carbon fibre construction means there is barely any flex when climbing hard out of the saddle or sprinting, but there is just enough damping effect to take out any of the harshness and vibration associated with UK road surfaces.

Three widths are available: 40cm, 42cm and 44cm, measured from centre to centre, with all of them having a reach of 80mm and a drop of 125mm – both slightly larger measurements than Easton's top-of-the-range EC90 Aero.

Easton says that the shape provides more comfort during long days in the saddle, and I found it worked for me, allowing full use of all sections of the handlebar without causing too extreme a riding position.

The central section is the now-standard 31.8mm in diameter and it comes with just enough width before the flat sections that you can fit an out-front computer mount, though you'd struggle to fit a light – the majority of 'see with' lights, anyway, as the clamp would likely be too wide.

Cable routing is simple as the entry and exit holes at the top of the hoods and the central section are wide enough to easily accommodate a brake cable/hose and a mechanical gear cable too.

Some handlebars don't have the cable holes in the right position or are too small, which can make threading the cables through a chore, but I had no such issues here. A little bit of jiggling the outers about to get everything lined up, but no swearing required.

There is no hole for a Di2 bar-end junction box, though.


The EC70 costs £229.99, which isn't cheap by a long shot, but it's still not as extreme as something like the Deda Vinci bar, up to £311.99 for the new DCR model (Matt tested the previous version last year, and that was £294.99), or the £459.95 Vision Metron Aero, up from £351 since we tested it in 2020.

Prime offers a more affordable option with its Primavera Aero, which Liam was very impressed with. It's only a gram heavier than the 42cm Easton in a 38cm width, but costs £149.99.


The EC70 Aero bar is a great upgrade in terms of comfort, looks and stiffness, with the only thing possibly counting against it being the price. It's not the most expensive bar out there, though, and the stiffness and the quality of the ride feel are worth the outlay if you have the budget.

Riders who use these aerobars and the one piece bar and stem getting more popular; the wider, flat shape of the top of the bars mean, when you are riding on the tops, the hand can't grip around with thumb on the back, so the palms rest , with five fingers facing front.

Watched a guy last week hit a pothole and he did a superman. Are they designed for riding on the hoods and the drops only?

Oh, I don't think they're all as bad, I have S-Works Aerofly II on one of my bikes and have no difficulty getting my (average sized) hand around the tops. Advice would be to try before buying I suppose.

Never seen anyone riding like that with aerobars, ever! Sounds madly uncomfortable. Mine are about 70 mm deep at the deepest flat part, no problem at all to get my thumb round the back. I suppose as a relatively large-framed man my hands are slightly bigger than others, but I reckon a bar would have to be at least 100 mm from front to back before I couldn't safely grip it.

In addition, if anyone is thinking of getting aerobars, if you have any wrist problems or arthritis they are a godsend due to the wider platform they give for the palm so less jarring up the wrist; my right wrist has been broken three times (two times rugby, one motorcycle crash) and can be a real problem on long rides on my other bikes, usually have to strap it up, on my road bike with aerobars absolutely no pain at all.

I have the Prime Primavera bar (highly recommended) and tend to be either on the hoods, or lower with wrists on the rearward part of the hoods.

I only ever use the tops when climbing for a long period.  Its actually a comfortable platform to hold as it spreads the pressure, and certainly scope to keep your thumbs behind to grip. 

Its also a nice platform for the (UCI banned) 'puppy paws' position, as the bar tops don't dig into your forearms!
