Easton EC90 Cranksets

DESCRIPTION

How do you make the best carbon crank in the world? Start by thoroughly testing every high-end crank currently available for ultimate strength, fatigue strength and stiffness. Then hand those numbers to a world class team of engineers and designers, with one simple goal: make a better one.

The result is the EC90 carbon road crank. At 558 grams, it packs the highest stiffness-to-weight ratio of any carbon crank currently available. It has also tested at over 500,000 cycles in a grueling fatigue test—five times longer than the nearest competitor. That’s almost unheard of in a carbon crank. (See comparison charts.)

To do this we started with our CNT Composite, the most advanced carbon fiber material in the bike industry today, and developed our own blend of foam core molding, bladder molding and compression molding to create a highly refined carbon structure, and a superior level of performance in a carbon crank. It doesn't get any better than this

    Weakness:

    Very good look but the quality sucks, 600 miles and no longer works

    So far, so good. No problems yet. I dont ride much, just on the weekends with an A-group, up and down hills with sprints. Im a litte under 150 lbs. Not sure if weight has to do with the problems others have mentioned.

    POS... total garbage. I had the same defect happen to my cranks after 6 thousand miles. It broke where the BB spindle adjoins the right crank.

    Easton discontinued these worthless cranks because of this recurring problem.

    Easton's cycling products are overrated

    WORTHLESS!! Crank failed where the spindle meets the spider. Easton will not do anything for me since I purchased off eBay NEW.

    Never buy anything for Easton, Bell or Giro since they are the same company

    Unsafe

    DO NOT BUY THESE CRANKS. There is a design flaw with them that Easton is trying to keep quiet. They are no longer manufacturing these cranks do to the flaw so they can not be warranty replaced. The spindle comes loose from the crank spider making the cranks wobble and structurally unsafe. Easton should really be issuing a recall for this product as they clearly know there is an issue.
    I loved this crank until it failed and Easton won't help me out.

    Weakness:

    Design or production defect that causes the spindle to come loose from the spider/right crank arm

    Unfortunately, life has not afforded me a lot of time on the bike this year. However, these cranks have not helped things out very much. I bought my first set of these cranks in August 2009 and only rode them for about 500 miles in six months. On the last ride, I noticed that there was a lot of play in the crank area and put the bike up on the stand. Just like another reviewer experience, the spindle had come loose from it's attachment to the drive-side crank arm.

    I took it back to Fat Tire Cycles (great shop, BTW if you're in Albuquerque) and they sent it off to Easton to be warranted. The warranty process went well, so no complaints there. My real beef with Easton begins with my second set of EC90 cranks, which I received a few weeks later.

    I put the cranks on, and put another 300 miles on these ones. I'm out riding yesterday, and the familiar "clunk" of the crank arm moving on the spindle comes back. I ride home, and sure enough it's the same problem again. Now, I'm living in Tucson and have to find a shop down here who can warranty them, or take/ship them all the way back to Albuquerque.

    I'm going to get them warranteed (presumably not going to get my money back after 1 year) and sell them. I'm not going to ride something (no matter how nice) if it's unreliable. Clearly Easton has a problem on it's hands with these cranks. They didn't address it at all with me, because they sent me a second set of cranks with the same problem. It tells me that they either (1) haven't found a solution and the cranks are still being produced with defects, (2) haven't pulled the bad lots from their stock, (3) they don't really care, or (4) some combination of the above. Either way, it doesn't matter with me, because the same problem recurring twice is the kiss of death for anything I'm going to put on my bike. I'd prefer to stay with carbon, but between this and some bad experiences with FSA, I'm just going to go with Dura-Ace cranks to ensure reliability.

    Preload bearing cap & Easton customer service!

    I purchased this Easton EC90 crankset with ceramic BB to replace the Ultegra 6600 crankset that came stock on my 2008 GIANT TCR Advanced 1. The price was great and the stiffness and weight savings are both very noticeable. The cranks spins so smoothly as compared to the Ultegra, and it looks great on my matte finish carbon bike.

    However, after about 250 miles, I was cleaning my bike and noticed the end cap that preloads the bearings on the non-drive side was gone! I don't know how that would have unthreaded and popped off from only 250 miles, but it did. So, I picked up the phone to call Easton customer service today and the girl I spoke to told me that they don't make replacement parts for purchase for this crankset. WHAT?!?! So, I can either send the crankset back to Easton or take to my LBS and see if they can replace it (don't know how they would unless they swap it out from another new crankset), possibly under warranty. Possibly? I then tell her that now my bike is rendered useless for 4-6 weeks if I send the crankset in and she just says "yep". That is like GM selling a car, but you can't buy replacement parts and have to send the car back to the factory if something goes wrong. How long has EASTON been doing business? Besides the facts, the girl did not show any empathy whatsoever for my situation. That is NOT customer service. I felt like I was talking to a robot. Well, I am off to my LBS to see if I can get it replaced and/or if I can at least ride my bike w/o the cap.

    I have had these cranks and bb for no more than 200 miles and they failed horribly. The drive side spun out of the cromolly connector and splintered the right crank arm. I am inclined to belive that this was a defect and not representative of Easton's products. I have had great luck with plenty of their stuff. This happend today on a sunday so I will see how their warrenty deparrtment is tomorrow. I am bigger tahn average for a cylist 6' 235, but no max weight was given.
