New Scott Foil RC promises TT bike speed and endurance bike comfort

Updated design is claimed to be faster, lighter and more comfortable than outgoing model

Scott says that its new Foil RC aero bike, launched today, is 20 per cent faster, 9 per cent lighter and 10 per cent more comfortable than the outgoing model. That bike was impressive enough on all three counts, so what has Scott done to improve on the design?

Scott says it has exploited the changes in UCI rules on frame design to overhaul the design of the Foil. The most obvious change is to the seat tube, which now wraps around the rear wheel, although the chainstay length and wheelbase are actually slightly longer size-for-size than the outgoing model.

The effective seat tube angle and the head tube angle are unchanged too. Stack is similar, although reach has increased on the smaller sized frames, so the new shape hasn’t greatly affected the bike’s geometry.

The whole frame looks to be heavily informed by Scott's Plasma TT bike, and the Swiss brand has used a canny cut-out seat post design in an attempt to improve comfort.

While you’ll see the pros of Team DSM riding the bike at the 2022 Tour de France, pricing and general availability are still yet to be announced.

Overhauled aerodynamics

Scott says that an update to UCI regulations in 2021 allowed it to rethink the new Foil’s aerodynamics. As a result, it worked with UK-based aerodynamics specialist Drag2Zero (also responsible for the design of Enve’s SES wheelsets) to look at the interplay between the bike’s frame, the components bolted onto it and the rider as a system, allowing it to fine-tune the design to save an effective 1 minute and 18 seconds over 40km at 40kmh compared with the old Foil.

The front end of the bike incorporates an oversized head tube that, Scott says, acts as a fairing to reduce drag. It also means that, as with the majority of high performance modern bikes, cable runs can be fully enclosed from the levers into the frame, both with electronic and mechanical setups.

Scott has also altered the geometry of the fork, with a deeper cross-section to the blades and a higher fork crown, both of which it says add aero benefits.

At the rear of the bike, there’s the dropped seatstay design typical of aero bikes, which lowers drag and also ups comfort. Scott claims that by angling the stays in at 10 degrees, they direct air into the wheel’s spokes as they spin, which it found improved aerodynamic performance.

The rear brake calliper nestles in the angle between the lowered seatstays and the chainstay, which Scott has found also improves aero performance.

There’s even more aero tweaking at the down tube-seat tube junction. Scott’s testing showed that its original prototypes worked great aerodynamically when it tested the frame only, but sit a rider on the bike and the aero benefits evaporated, resulting in poorer aerodynamic performance than the previous model.

Efficient fabrication

The main quibble that we had when we tested the old Foil was its fairly portly 8kg weight, but Scott’s new carbon layup and construction involves fewer separate pieces, thereby decreasing the number of joints in the frame by 30 per cent, This has resulted in a 9 per cent reduction in the bike’s weight, while still retaining the same stiffness as the old Foil.

Scott says that the Foil RC Ultimate frameset, which uses a higher spec carbon than the rest of the range, weighs 915g and the complete bike weighs 7.22kg – no size or paint information provided – so a pro-level build, as will be ridden by Team DSM at the Tour de France, could potentially skim the UCI’s 6.8kg weight limit.

Comfortable componentry

Scott’s Syncros component brand provides the integrated bar/stem and the seatpost, which Scott says are integral to the new Foil’s claimed 10 per cent increase in comfort as well as adding to the bike’s aerodynamic efficiency.

There’s a new, slimmer bar/stem combo, with a significantly lower frontal profile. Called the Syncros Creston IC SL Aero, it has been wind-tunnel-tested to improve on the aero properties of the old Foil’s bar design.

Scott also claims to have upped both comfort and stiffness with a construction that manages to combine greater compliance when under light load with increased stiffness when in the drops – it’s unclear how that works, though.

The combined bar/stem is fitted to the top two models in the four model line-up, the Foil RC Ultimate and the Foil RC Pro, while the lower spec Foil RC 10 and Foil RC 20 get a two-piece bar and stem.

The patented seatpost goes by the name of Syncros Duncan SL Aero CFT. The actual load-bearing part of the carbon post is a slender portion at the front. Scott says this adds flexibility and comfort over bumpy surfaces.

At the rear, there’s a detachable section that completes the post’s aero profile. Is it a fairing? Apparently the UCI doesn’t think so as it’s approved the new Foil’s design.

You can buy a separate USB-rechargeable rear light unit that slots into the rear of the seatpost and so doesn’t alter its aerodynamic properties, giving you three light modes with up to a 20-lumen output.

The new Foil has clearance for tyres up to 30mm wide – not huge by today’s standards but enough to add extra road smoothing. Scott fits a 25mm tyre up front and a 28mm at the rear when you buy the bike.

There are four models in the line-up; ahead of the launch Scott hasn’t provided information on prices or availability but there’s more info on the new Foil at scott-sports.com
