The EC90 Aero wheel features a 56mm deep carbon section that slices through the wind with ease. Thanks to its excellent aerodynamic qualities, the EC90 Aero 56mm wheel has become a favorite of time trialists and triathletes alike. The EC9...
Weaknesses: Heat related braking surface failure. Hub failure.
As a 70kg rider I was very disappointed that 2 front and 1 rear wheels failed because of heat build up on the braking surface. Heat build-up and failure pushes the plastic through the carbon fibre weave, which then causes a very unpleasant grabbing and uneven braking. The braking surface even forms a concave groove around the entire wheel. In addition, the rear hub had a known problem, was replaced and then ultimately failed. Both failures are in the 'dangerous' category. I'm now very happily riding on Zipp 303 Carbon Firecrests.

Strengths: Stiff, rolls quick, very good on climbs and reasonably priced.
Weaknesses: I've dealt with the noisy brakes using their pads but I upgraded to corks and it brakes well. Just can't use on rainy days Sunday. But after learning carbon don't really go well in the rain. I baby my bike. No Rain, trainers if it rains. That's it!
I almost sold these after updating them to all ceramics but was not successful selling them so I kept it. Well after being in storage and after three bike updates? I've decided to laced them to my newest and rode excellent. Came in second on my recent race.

Strengths: Ride, stiff, look, relatively light.
Weaknesses: Breaking is a major issue. With my set carbon particles keeps on being transferred on to the pads glazing the contact surface. Once they are glazed, the braking power is down to 20-30 % compared to my other set of carbon wheels. I think there is a problem, I honestly consider this wheels dangerous in a group ride since it is almost impossible to stop at the same rate as any other rider. Also I have to send down the pads before every ride, which is kind of a nonsense.
Just bought the wheels and I love almost everything about them. The ride is plush, laterally is very good, the free-hub (I use Campy) is not the best. Pay attention as to how the cassette is inserted as it is possible to slide it in wrong. I noticed that the 11 and 12 teeth gears are a little loose compared to the rest of them. The major problem is breaking. I consider my set dangerous. I sent it back and the guys at Easton have been very helpful, but even if I only had 3 rides, they are not willing to replace them. They suggested cork pads. I am not very happy but I will give it a try.
Strengths: Fast. well made. light. look good. climb and cruise well. a great addition to a bike.
Weaknesses: One HUGE problem. braking surface breaks down under heavy use on descents. I have destroyed 2 sets this way, and yes I used the recommended pads.The mtns are very steep here and the corners are very sharp, which heats up the rims until, after not that many rides, they bubble and the rims warp and crack. Under all my other testing they are great. But Im going back to alu rims, sadly, for training in the mtns. Oh well.
Ok I do love these wheels. They are quick, stiff comfortable, spin up fast, accelerate and ride well, are (mostly) very durable and are not nearly as expensive as some of their competition. Ive ridden them in many places with no issues. I have had one huge problem with them, but I'll explain that later.
Im needing advice on a wheelset!! Easton EC90 Aero clincher. Im a pretty big guy 6,3 265ish very strong watt pumping legs!! I see there is no listed weight limit. im scared the 20 spoke rear wheel may run into issues down the road. This is suppose to be a pretty stout wheelset and cyclecross cap ... Read More »
I'm looking at getting a new set of wheels and I can't decide between these 2. I've narrowed it down over the past week and I am only considering these 2 wheelsets. Please don't recommend any other sets as I've considered everything else already and have finally narrowed it down..

First of all, pardon the cross-post, but the Easton forum appears to be "less travelled" than this area.
I've had this wheelset for just over a year now, put a few thousand KM on them, and nary an issue.
However, lately I've noticed that they are developing "loose threads" Definitely from the ... Read More »
