The final piece! Easton EC90 SL Carbon Cranks



So the final piece for the Open U.P. build has finally arrived. It’s the Easton EC90 SL Carbon crank with a 1x direct mount 42T chainring. In this video, we’ll take a closer look at the crank and the Cinch system, and I explain why this will replace my old Dura Ace 9100 crank.

    Do you have any noise problem with those? After maybe 500 km mine developed some sort of deep below knocking kind of noise (took me a while to realise its coming from cranks), there was no visible play but tightening up a preload collar helped… For maybe 100km, now it makes something like clicking – not on every rotation though, mostly when going uphill or pushing hard. Just tried tightening the preload collar again and it seems that I can tighten it sort of forever – it probably just jumps over the thread.

    I really like you videos alot. I'm considering getting a gravel bike and make it 1x. Would you be able to make a video explain things like you gear set up and how well it compares to your experience of 2x set ups please.

    your video chops are strong. Another channel showing how you achieve some of your effects & cuts? Another great and enjoyable video (I'm in grave danger of reaching the end of your back catalog!) Peace!

    Yeah, the Easton crank looks super!
    I am caught up in the weight weenie thing as well… just forked out some big money on a Dura Ace 9100 cassette with titanium cogs, 11-30T ,the weight difference from my Shimano R 8000 11-32 cassette is substantial… a couple more changes and I should be at 6.9kilos on my Specialized Tarmac!!! 🙂 🙂
    But crap is it expensive to get to that weight!!!! But sooooo soothing lol…

    I recommend upgrading the preload collar with Cane creek preload collar, cus the stock is junk, the screw rounds off, it gets loose fast, the preload collar is not as precise and smooth to turn, btu h Cane Creek is.
    https://www.worldwidecyclery.com/products/cane-creek-alloy-preload-collar-with-ti-bolt-for-30mm-spindles#
    that's what I did with my cranks, so far the titanium bolt has not rounded off, and does not loosen as fast., and smooth preload adjustment.
    I am not into road bikes, I just found you channel randomly. So I share what I know.

    Cool! You inspire me to get SL90:s as well. However i will run there Gravel Rings 46-30 and pair with a XTR 11-40 Cassette. I tried it in the lab and my R8050 GS RD handles it like a charm when i add the WolfTooth Roadlink DM.

    With this seup i get a 570% range (SRAM Eagle is 500%!) and can quite easily also change to 1X or a a more roadlike cassette within minutes.

    Thanks for all the great ideas you give me and perhaps this is one back to you?

    Cheers and looking forward to you completing the build, now out for a four hour ride in Stockholm, 2 degrees, rain… Longing for spring.

    My friend ceramic 🐻💍 do last longer than steel bearings. Yes there are very good steel bearings like the ones Chris king use or fag ones , but since I have used ceramic speed ones on my crank about 3 years ago, I have done 7k plus miles and they still very very smooth and no play or noises.

    Thumbs up within the first 58 seconds…. Finally, I have the same level of enthusiasm for a crank set (Praxis Carbon Zayante Direct drive running a that AbsoluteBlack 48T Oval chainrings), total weight coming in shy of 500g. BTW, did you look at the Praxis one ?

    I'm loving your videos. Good content & humour….keep it up.
    Just one question. I'm thinking of buying an 'all road' bike. I'm still not sure if I want 1x or 2x. My current road bike is 2 x & my MTB is 1x. I find my MTB has big jumps between some gear, so I'm either in a too high or too low a gear (it's a 3 x 10 to 1 x 10 conversion).
    As you have been riding a 1x for a while do you find that you have this problem, especially on the road or not?

    I was going to install exact crank on my trek Crockett… ran into trouble fitting the Easton BB so aborted… it did not want to fit and I didn’t want to risk damage to the frame. In the process I think I toasted the $50 Easton bb. The sram fit back in without a hitch. Hope to throw this crank on my next bike! Looking forward to the rest of the build!

    If my frame supports bb386evo, I would jump to 30mm spindle. However 41mm OD of bb86 makes it super hard to get a long lasting bb for 30mm spindle.

    Good for your UP frame.

    Hey Tobias. Great to hear you are going to pedal back again soon.

    Some feedback for the new build video: I'd would be helpful if you enumerated clearly the steps you are going to follow to build the bike at the very beginning, in the first video. Then when you move to any of the steps, you can show that "slide" and highlight the step you are going to attack. Just my two cents.

    P.S: Strong intro. I see you working on movie credits soon. ☝🏻

    I'm excited to see your new build, and hear that you are healing up nicely! I'm trying to hard to not be a weight weenie myself. Luckily (or maybe not luckily) I have a few extra kilos to lose on my body. Dropping those is my weight-saving goal for next year.

  • August 7, 2019 at 8:29 am

    Yes massive savings for a weight weenie! I swoon at the very thought of such a massive reduction in weight. I'm getting goose bumps at the very thought!!!!!

    Love your vids! What are you doing about the lack of Di2 protection cover under the bottom bracket? I understand one is coming from Open but isn't here yet. I've used tape 🙁

    Cool video on pretty cool cranks. Fully understand your facination on them… I got Race Face Turbine Cinc 1x on my mtb full and they´re really great. And as you mentioned, with new piece to puzze you can buy as well a new equipment to you tool box 😀

    Congrats! The Easton is a great crank! But be mindful when mounting the Easton BB. I had issues. The spindle did not go through easily already while not even mounted in the frame. Probably due to poor quality / specs control with the BB. So it proved difficult to preload the system. I mounted it in my Open UP nonetheless and ultimately the whole system developed heavy creaking. Changed the BB to an Enduro Torqtite screwed BB and could not be happier.

    Hi Tobias, i´m a casual cyclist, rode BMX when young, used to ride mtb bikes my hole life for all purposes, including long backpacking bike travels… than road bikes, even fixed gear bikes on urban and roads….i lived for 2 years in Japan, riding an only hybrid bike for everything, went to home country Brazil for 3 years, there i used a single speed 29 mtb for all… and i´m just went back to Japan this month…no bike for while…gonna wait pass winter time to keep some money, and for while. I was thinking about have a one bike for ll purposes, and i´m doing research if a gravel maybe would do the job, considering my riding wishes nowadays… 😀 So i found your channel here…what a great gift!! Thank you so much in sharing your experience. Starting to watch all the past videos, for sure it will help me a lot in figure out wath gravel bike set up will fit. Living in Kyushu (Oita ken, Nagatsu shi for now….Happy to see that you are just coming back from the recovering time! Wich you the best rides…this country is amazing to ride a bike..

    I think the distinct advantage that you eluded to, though may not be particularly useful in your case, is the ability to use other (e.g. smaller) chainrings with that crank. I think that DA is limited to the 42T, which is great when you aren't packing weight, but not so great with a load. The Easton is the obvious choice!

    i loved the aesthetic of the dura ace crank with those chainring, did the same with my ultegra one and a B.O.R round chainring

    Passion is not reason…. good choice, very nice cranks
    In japan, what is the price of Open frame ( in France 3000€ )
