Review: Scott FOIL Team Issue — An aero road frame without the compromise
Magazine, we reviewed four aero road bikes : a Cervélo S3, Felt AR1, Ridley Noah, and Blue AC1 SL. Each was put through two scientific tests plus over 30 hours of ride time. The Scott FOIL was not yet available during our test period, and so it was left off the list.We don’t usually publish VeloLab bike reviews on VeloNews.com; that content can only be found in Velo magazine. Consider this online review — a first for us — an addendum to our April roundup. The format is a bit different, but we put the FOIL through the same rigorous test process as we always do for VeloLab reviews. Like what you see? Aero road bikes round 2 is on the horizon, but you have to subscribe to see it.
So with our magazine sales call out of the way, on to the test.
The FOIL: aero shape without the compromise The FOIL doesn’t look like an aero frame. There are no slender tube shapes or wheel cutouts, and no ultra-narrow head tube. In fact, Scott has had to use paint to show just how they’ve made it aerodynamic at all.
The concept behind each tube shape is similar to the Kamm-tail used on Trek’s Speed Concept TT frame : cut off the back of an aero profile to see aero gains while using wider, stiffer tubes, while also staying within the UCI’s 3:1 tube profile regulations. Sticking within those regulations while using regular NACA profiles necessitates skinny tubes, as seen on other aero frames currently available. On the FOIL Team Issue, red paint indicates a truncated aero-profile tube.
The result is excellent: an (allegedly) aero frame, saving its rider a claimed up to 20 watts at 45kph, without the downsides associated with skinny aero tubes with thick walls. Free speed, without the negative side affects traditionally associated with going aero: a flimsy front end and dead-feeling ride. Even if the aero claims are overblown, which I don’t think is the case, I’d consider the FOIL a good buy based on its stiffness and ride quality alone.
The FOIL produced 43 percent less deflection at the head tube, 21 percent less rear end deflection, and the second lowest bottom bracket deflection on the same Microbac Laboratories torsional stiffness jig when compared to the stiffest aero bike in each category tested earlier this year. That’s an overall frame deflection sum of just 5.22mm, compared to 6.89mm for the Ridley, 7.20mm for the Blue, 8.43mm for the Cervélo, and 8.80mm for the Felt AR1.The FOIL’s stiffness numbers fall close to those of the high end, non-aero race frames tested in the WorldTour bike test found in the September issue of Velo . In fact, the FOIL would have been the second stiffest in that test, despite its aerodynamic tube profiles.

What is the best boxmakers clamp? - Woodwork Forums
Ok I am really fed up with warped frames. I have been using a frame clamp which just warps the frame and panel. There are various design out there but I have not seen a design which keeps the frame straight horizontally and vertically and is easy to use. Is the solution a band clamp for boxes and frame and panel gluing? What have people found the best solutiion. I have seen the design in Gifkins instructions but it is alot of work to build.
