RedSky – The Ultimate in Versatile Performance

Yesterday, we introduced Project RedSky. Today we want to look at this bike’s incredible versatility. To demonstrate, we offer photos of an eTap equipped RedSky wearing a wide range of tires.

With 23c tires, RedSky looks like any road bike. What you will notice, as we step up from 28c, to 32c, 33c, and finally to 30c studded, is that the bike always looks proportional, always looks purpose-built.

RedSky can very literally be your go-to fast, group ride bike, and also your winter time commuter (with 32c tires and fenders). You can ride mixed-terrain on it with an array of file treaded tires, or you can tour on it. It has hidden rack mounts at the dropouts.

We know a lot of our riders are hesitant to move to disc brakes, because they have already invested in quality rim brake wheels. RedSky solves this problem by giving those riders access to the same tires as they might run on a mixed-terrain or cyclocross bike.

    • Dorsey, RedSky is more versatile and thus probably a better choice. The randonneurs we know (including us!) like to use a wide range of tires depending on distance, surfaces and general style of riding. RedSky is perfect for that.

      • @Bruce and Ed – The RedSky is available for order now. We are working full tilt to get the builds and photos squared away to get each model on-line, but in the meantime, we are taking orders and delivering bikes. Thanks!

  • Looks like a fantastic bike, especially with the Rene Herse crank shown in the previous blog post. Versatile gearing, light weight, and low q-factor with that crank. Minor quibble – please describe tires properly by their width (28mm) and not mix up the fairly arbitrary “c” that comes from the 700c wheel size. There’s no such thing as 28c, but there is 23mm, 28mm, 32mm, etc. Really 🙂

  • Hello,
    This is exactly what I want for my next bike. Can I choose Elium SL in Red Sky version? What brakes do you recommend if I were to use SRAM RED groupset, please?

    • @Joe – SRAM doesn’t seem to make a medium reach brake. We’d probably recommend the Velo Orange Grand Cru as on this build.

    • Gene – We already build the Evergreen line of disc-brake mixed-terrain bikes. The RedSky is meant to be an alternative for folks who prefer rim brakes and have good wheels they’d like to keep riding.

      • Peter Middleton says:

        Really like the sound of the RedSky. I am a believer in wider tires even for paved roads.

        If I am thinking of disk brakes, you refer to the Evergreen. You know your bikes better than me, but the description of the two they sound a little different
        – RedSky sounds exactly what I am looking for (ability to mix riding on paved / poor quality paved / and unpaved roads) while also use wider tires and rims at any time.
        – Evergreen sounds less suitable for paved roads (and does not mention ‘fast group rides’, but does mention ‘Mountain expedition’)

        Likely I am too focused on words – need to actually ride the bike !

        For ease of reference hear are the words your web-site uses
        RedSky SL:
        “Light, comfortable and built to go fast, the RedSky SL features our Argen™ double-butted tubing, the most tunably compliant tubeset we make. Pair it with a slick 25mm tire for fast summer miles, or switch over to 32mm studded tires for all-winter riding.’
        Usage: Fast Group Ride, Solo Ride, Randonee and Endurance, Touring, Commuter and Urban”

        Evergreen SL:
        “The Evergreen SL is a great choice for riders wanting to test their limits over dirt and gravel. double-butted titanium eases the impacts from ruts, potholes and the sorts of imperfections that distinguish Class IV roads from their smoother, paved brethren. Highly tunable handling is wed to disc brake stopping power to keep you dialed-in to the ride even after hours in the saddle.
        “Usage: Solo Ride, Randonee and Endurance, Commuter and Urban, Cross Utility, Mountain Expedition”

        • Peter, the main difference between these bikes is the brakes. The RedSky is a medium-reach road bike, which is why tire width tops out at 33mm, while the Evergreen is a disc brake bike which will clear tires up to 45mm.

  • So, Redsky and Evergreen are identical except for the brakes? I’m narrowing my choice to between these two. I’d prefer discs but want a randonnee machine with a road geometry to which I can fit fenders- for official audax events, club rides I’d take them off.
    I want the ability to run a wider tire, probably 28mm but I need to think if 32mm makes sense (more analysis required).
    Fwiw, my goal is to ride PBP 2019.

    • Greg,
      For folks doing the riding you’re doing, we think the RedSky is the best choice. You can get all the way to 32mm tires on the RedSky, or you can go with 28mm with fenders. The rim calipers will leave this bike nearly a pound lighter than a comparable Evergreen.
      Hope this helps,
