MTB Tech for Road and Cross Bikes: Easton’s EC90 SL Cranks Get the Thumbs Up! Feb 21, 2017

It was a game changer when 1x drivetrains made the leap from mountain bikes to drop bar bikes. Last year when RaceFace purchased Easton, the merger promised a bit of cross-pollination between RaceFace’s MTB technology and Easton’s road 1x systems. The EC90 SL crank adopted RaceFace’s Cinch system, allowing it to utilize direct mount 1x chainrings and direct mount 2x spiders, all in a road q-factor and chainline. This makes for an incredibly versatile crank interface that not only looks good, but in my opinion, out performs many other cranks. I’ve been riding the EC90 SL cranks on my firefly with a 38t direct mount on SRAM’s 1x Force system with a 10-42t cassette. Mounting them was easy, and there’s a new found confidence in Easton’s beefy bottom bracket. Especially when compared to SRAM’s GXP offering which always seems to creak right out of the box.

While weight isn’t a major concern of mine, these cranks weigh around 450g for 175mm and a 38t. The 30mm spindle and solid carbon construction feels great and the precision-machined chainring has yet to kick a chain, even on our rutted, steep and washboarded descents in the Los Angeles area. So, yeah, for around $350, the cranks alone are not for the penny-pinchers, but considering weight-weenie cross racers will drop a considerable amount of money shaving grams on their race rigs, the extra $100 for a +/- 200g reduction might make sense. Also, these are made in Canada!

For me, the looks and reliability of Easton’s products merit the pricepoint, yet for that kind of dough, you’d think they’d offer an all-black version. If you’re spending a lot of money on carbon components, why do companies insist on pasting their high contrast, white logos on them? For those of you looking for a light crank, where weight reductions matter and has the option to be run as a 2x, consider checking out the Easton EC90 SL cranks at your local dealer.

    For reference, my 172.5 Sram Red 22 cranks with a 40T CX1 ring came in at 498g. These Easton cranks are pretty light!

  • M. Heron

    are these any different than the RF Next SL?

    • Same crank, but with a road Q factor and chainline. RF never made road cranks.

      • M. Heron

        Yeah, I have the next sl on my mtb, and the arms look to be identical. Just curious!

        • Adam

          The arms are a different shape, but similar construction and manufacturing method. The Easton arms are lighter than the NEXT SL G3 or G4 arms, and like John said they have a different Q Factor and CL.

          RF has made road cranks, they were called Cadence, but they were lower end to mostly be sold as OE.

  • Really looking forward to trying these out.

  • Chris W

    Made in Canada!! These will be going on a future build for sure.

    • Yes, forgot to mention that awesome point!

  • Got a set on order for an upcoming “dream bike” build (out of stock, not surprised). Can’t wait to see how they build up!
