anyone risk using aerobars on Easton EC90's?(8 posts)

anyone risk using aerobars on Easton EC90's?BenR

I know they're not supposed to be used with aerobars, but has anyone done it anyway? Results? I'd be using them for time trials once/week only. Short durations but lots of off & on, off & on...I like my bones and don't wish to destroy any potential resale value of my bars, but was wondering if the bars truly can't withstand the clamping or if Easton is just worried about liability issues.

I don't really like the Eastons I have, but have limited funds for trying something else. Any experiences with Kestrel (if I can find a pair used), Ritchey WCS, or newton bars? Others? Stiffness and fatigue life are more important to me than being stupid-light. Also looking for less straight-section-to-hood reach than the eastons but perhaps more than the 3T offerings. $100 max price. Thanks.

Why do you think the manufacturer tells you not to do it?
what about selling your EC90 bars ? I'm interested....PeterRider

... depending on size and price.

email me bjrhode@wsu.edu

I'm still looking for bars and I need to use them for the next week or two since my training bike just crapped out on me.

44 cm c-c
They were ridden an avg. of 175 miles/week roughly from August 1 to October 1, raced in one crit (never crashed) and then ridden sparingly all winter. I was hoping to ship for $90, let me know if you have more questions. I'll tell you what I think of them later if you're still interested and can send you pictures soon as I get them off the bike.

There was a mention that Easton was going to offer a pair of aero bars that could be used with the EC90's back at interbike.. haven't heard anything since though.

Easton says the reason not to use clamp on aero bars is because they don't clamp evenly. Unlike a stem which is designed to evenly spread the clamping force across the bar, aero bars pinch the bars and that is very very bad with carbon bars. Also most aero bars have a not exactly round clamp.... that's a bad thing with the carbon bars for clamping forces. It can pinch or gouge the bars and cause them to fail.

As for other bars you mentioned... if you want to use aero bars, go aluminum. You won't benifit from the carbon bars anyways on your aero bars. Carbon bars are light, but there are light aluminum bars out there too. The problem is you are meant to hold them, not to lean on them. So get a nice aluminum set. You won't see the damping qualities of carbon when in your tuck anyways.

As for the Newtons, I would recommend the Magic instead. They are half the price and only 20 grams heavier, but substantially stronger. It's funny that many pros who are riding Deda actually ride the Magic bar with the Newton stem. The stiffness in the bar is better for climbing and sprinting and the weight penalty is not too bad. That's the same set up I use and I love it.

That's what I was afraid of, just wanted to make sure it was true before I went through with the bother of changing bars. I have a couple friends that use their aerobars on their Eastons and it just doesn't seem smart.

Thanks for the info on the magic bars, I was wondering what the difference was from the Newtons, but had been "steered" wrong by someone who claimed that Magics should be flexier given that they are only 20g heavier and much cheaper (he was thinking they were using a cheaper alloy).

As for the carbon bars, I've never been bothered by increasing vibration when switching back to aluminum. They're out of my price range, not worth destroying in a crit, and I can easily drop 40 grams off the engine, so thanks again for the constructive advice.

I talked to the Easton rep 3 years ago about aero bars and he said they were working on some. I had problems with the carbon seatpost and they did replace one under warranty and the replacement had the same problem. The surface epoxy or gelcoat is too soft and will dent. This could cause the carbon fibres to break which would not be a nice experience to have. Since they haven't come out with their aero bars, I think they must be having some issues with them.
