Easton EC90 Fork
View Full Version : Easton EC90 Fork
I am thinking of updating my 2006 Cannondale six13 Pro by updating the cannondale fork. It weighs about 450g (cut) and I figured I would be taking the hrashness out of the ultra stiff ride it gives me by putting on a curved Easton EC90 fork aside from shaving off a nice 150g bringing it down to 7,45kg all in. Question is , shall I presume that most 1 1/8" forks are compatible with all frames with a 1 1/8" head tube or are there any other factors??

Nurul, does it have a carbon steerer or alloy?

I believe that the Cannondale fork has a carbon steerer.

To answer your question most integrated forks should work fine with the 1 1/8" headtubes. I replaced an integrated Pinarello fork in my Opera with a Reynolds. I re-used the crown race, but overall its flawless. In fact the Reynold looks nicer and is lighter too.
My Giant TCR frame, with integrated headset, accepted an EC90 Aero without any trouble. I also re-used the crown race.

My Pinarello Opera has a proprietary internal headset so the crown race was not an option. My CAAD8 has an FSA integrated HS, so i think I could find a new race if needed.
I will regurgitate everything I've learned in the last month looking to replace the Slice (Ultra) fork on my 54 cm CAAD 7 - I don't know if the fork geometry is the same as your frame, but in my experience the fork geometry was / is similar or identical across the CAAD frames, If I were to have to guess, it would be that all Slice forks have the same geometry and differ only in what the steer tube and drop outs are made of. You can check in the archives on cannondale website. You just need to know the leg length and rake - and then look for any fork with similar measurements designed for an integrated headset.
My Slice fork is a 367 mm leg length and a 45 mm rake, integrated headset. There are many excellent brands - Easton, Reynolds, Columbus, Deda, Alpha Q, etc that will get you very close if not identical to that in leg length and rake. Almost every fork I've found data for is available in a 43, 44 or 45 rake and a leg length 365-370, which means most are very similar if not functionally identical to the Slice, but you should check.
My personal opinion is that you probably won't notice a leg length of + or - a couple of mm (<1/16 inch) and a rake + or - a mm (~1/32 inch). Most credible postings I've seen is that it is not meaningful as long as you stay close. I sometimes wonder if mfgr fork specs are really accurate within a mm or if "367" really means "366-368" or such? Some actually list length within a mm or two range.
I think 374 is the longest road fork I've seen. I wouldn't go that far with my frame, but it might not be a factor for you depending on what is on it now.
Look for a fork that is made for an integrated headset. I think any fork will work, but visually, the one designed for integrated will look, er, like it is supposed to.
Used or aftermarket Slice forks seem to be very rare on ebay for what it's worth. That means you should be able to sell yours pretty easily for a good price.
Finally, for what it's worth, you can find new-old-stock (NIS) name brand forks on ebay for as low as $100-$125+ at auction and ~$150 buy it now. Those will be of the alloy dropout variety which probably won't save you any weight worth considering. Be especially careful of the New Old Stock (NIS) Ouzo Pro forks. Some weigh in at 450 gm which won't get you anything, whike others that look identical are 370. You can find less known brands like Hasa or Aerus for somewhat less cost for similar specs. I haven't read anything bad about those forks, but they definitely are cheaper. You can also find no-name / unbranded forks for even less. At the other end are the Eastons and Alpha Q's, and other higher end forks which seem to be going for closer to $200+ and will get you closer to 300 grams.
Anything significantly lighter (say in the low 300 gm range) than your current will probably have carbon drop outs, which I didn't happen to be interested in since I literally take my front wheel off and on daily. Plus, like I said, going from my Slice Ultra to a middle of the line 370 gm fork was a big change, but would hardly be worth it for you.

Thanks Camilo. As I have got the six13 down to 7625g all in with pedals, cages and sensors, I've got a litle project to see if I can get it down to 7000g before the end of 2009. New forks (EAston EC90 -150g), new post (Record -50g) should get it down to about 7400g. The fork is a good start and should also smooth out the six13.....

You might be able to find the weight of your current fork there. They have several types of Slice forks listed. You might also check out your candidates for seat post as the one I have(Bontrager XXX) is way over claimed weight. Not that it matters all that much to me, but if I were to do it over again, if I were to want to spend that much money on a carbon post (probably wouldn't), I'd get more bang for the buck, weight wise.... which wouldn't be hard.
Thanks Camilo. As I have got the six13 down to 7625g.......man, man, man, like I keep saying, you belong on Weight Weenies, not here. Those guys are nuts. http://www.musicianforums.com/forums/images/smilies/thumb.gif
On Weight Weenies, all your weight-cutting 'urges' will be indulged and satisifed to your desired climax :D

This is what I raced on last Thursday: a bike with a 1600g resprayed Norco frame, a 550g Roselli carbon/alu fork, 2130g DT RR 1.2 wheels, and 9sp Dura-Ace (with 10sp cranks)! Plus the plastic brackets for my pump and lights, so I could ride home afterwards. I don't know what it weighs, but I'd be amazed if it was under 9kg. :p
