The Scott Foil was already known for being a light & aero race bike that wouldn’t beat you up on the rough stuff. Orica-Scott rider Mathew Hayman even rode one as the first aero bike to get a Paris-Roubaix victory. Scott has talked of modernizing with road discs for a few years. So it was time that the light aero bike gets the disc brake treatment for improved control and rider safety.

2018 Scott Foil Disc aero disc brake road bike

The new disc version build off the has the same proven frame design & construction of the rim brake bike, and claims to still be one of the lightest aero bikes on the market at a claimed 985g, even with discs.

The frame itself looks almost entirely unchanged, from the same integrated Syncros cockpit up front back to the same (proprietary) aero seatpost with an improved hidden clamp, dropped seatstays, and subtle rear wheel cutout.

For the most part that all remains thanks to the rim brake version already having pulled the rear brake off the seatstays and tucked it behind the bottom bracket.

Tech details

Now a flat mount disc caliper just slides into a reinforced chainstay, next to a new 12mm thru-axle.

A small but very thoughtful detail, the Foil Disc gets a specially tapered dropout design that helps guide the rear wheel into place. We’ve dealt with enough thru-axle bikes where it was a chore to align the rear wheel to insert the axle, and it looks like Scott has a nice solution.

Scott pairs that axle with two different rear derailleur options – either a traditional hanger or a Shimano direct mount version which provides extra room to make wheel changes faster & easier.

Reshaping the bike for new brakes is more dramatic up front. The Foil Disc gets new prominent fork tip flaps that are said to minimize drag around the hub and caliper, and to optimize performance in cross winds. The all new, full carbon flat mount disc fork adds a 12mm thru-axle with removable lever, internal routing, and boosts clearance for up to 30mm tires.

The HMX carbon Foil Disc retains the comfort the Foil is known for with its dropped, thin chainstays and ‘Comfort Zone’ rear end construction, now tuned for disc brakes.

The disc bike carries over their single-point-of-entry modular full internal cable routing,  a PF86 bottom bracket, an integrated front derailleur tab, and integrated anti-chain drop device, and a stainless anti-chain suck plate.

Complete bike builds

Scott has three complete versions of the Foil Disc, all of which come at a premium. Each shares the same frame & fork and are available in a wide seven size range (XXS-XXL). The entry Foil 20 Disc starts at just $4800/3600€, built up with a full Ultegra groupset.

At about $6300/4800€ you will find the Foil 10 Disc that upgrades to Ultegra Di2.

The the top Foil Disc Premium climbs to a whopping $13,000/12,000€, built up with Dura-Ace Di2, Zipp 303 NSW wheels, and the Syncros Carbon Foil Combo cockpit for a claimed weight of 7.25kg (15.98lb).

  1. DON’T YOU KNOW THAT DISC BRAKES ON ROAD BIKES ARE DANGEROUS?!?!?

    Every year THOUSANDS of mountain bikes have never been injured from these dangerous devices.

    There’s stories all over the internet of severed fingers and slicey things happening, and the internet does not lie.

    The increased control, modulation, and overall stopping power can cause you brake later, corner smoother, ride more cofidently, and descend faster, which can lead to severe injury or DEATH!!

    DO NOT, I repeat, DO NOT put yourself at risk, Those things look like a little like an Italian deli’s meat-slicer, so they surely must be just as dangerous!

    • I don’t think people are really belly aching as much as they used to around disc brake road bikes being dangerous. Most people who have raced in the last 12 months have probably been in a pack with disc brakes (USAC doesn’t enforce the no disc brake rule). I think the larger consternation is around this mentality that rim brakes are dated garbage and need to disappear. I love disc brakes but frankly for a race bike I prefer a rim brake set up. Far easier to live with especially when traveling and to me 28mm tires at low pressure and rim brakes are superior to 25mm with disc brakes in the rain but as a “cat IV 4 life” who will never win anything but a TT I get to be soft and skip wet races.

      • I’ll add.
        I think discs are great. But they are not a free option for many. I just received a warranty frameset, and had the option to get the new disc version. I am running pre-’15 campy chorus, so converting to disc would cost about $2-2.5k all said an done, whereas it’s essentially free to transfer my existing stuff over. Nobody can convince its worth it as I’ve never had a braking issue on rim brakes. Even if I had 2015+ campy or Shimano, it would still cost me $1500+.

        Its kind of a paper argument or like asking if I think a 14.5lb bike is better than a 15lb bike. Sure, but at what cost?

          • He’s talking about replacing a whole group. To be fair though I remember looking at building a disc brake road bike up and realized I could build up a bike with 6870 di2 for less than the cost of the new hydraulic groupset

      • From my amateur racer experience.

        Discs are great but:
        1) I personaly saw a person hitting other rider rear brake rotor with this ankle. No crash just sudden decceleration by peleton and boom he is out of races for some months
        2) If you raced some big mass start races in a mountains few years ago (no discs) and now (many riders on discs) it is obviuos that on descents things are more chaotic and dangeruos. Totally different braking dynamics by rim and disc brike riders.

  2. Love integration of a chain catcher on the frame. I used to use deda dog fangs on my alu frames that didn’t have braze on FD’s but when I switched to carbon I’ve had to use k-edge which I find really doesn’t do much in occasions of true chain suck this seems to work similar to the dog fang.

  3. My comment is based on converting to hyd disc of equal shifter quality. Mechanical disc gives me no advantages over rim brakes on a dedicated road bike.
    Hyd shifters + calipers + discs + wheels of equal quality = $1500 easy

    • “Mechanical disc gives me no advantages over rim brakes on a dedicated road bike.”

      They give you predictable power and modulation in all conditions, just like any disc brake does vs. a rim brake. Hydraulic offers longer maintenance intervals (no cables/housing) and more power.

      I wouldn’t pay $1,500 for the upgrade either, but I will always choose bikes with disc brakes whenever I get a new one.

  4. I think disc brakes are the only way to go, no matter what bike you ride. I don’t even look at bikes that have rim brakes anymore. My only concern about road, cross or xc bikes, is using thru-axles. Don’t get me wrong, thru-axles are great on most mountain bikes but I believe they are an overkill for all others. This is why I’ve designed the”Open 15″ and Open 12″ dropouts, which are essentially 15mm and 12mm open dropouts, which use a 15mm or 12mm axle that stays in the hub. Works exactly the same as a 9mm QR, but has a larger clamping area and a stiffer axle.
