Peter Verdone Designs the New Firefly Disc Dropout Oct 7, 2014

If you’re an industrial or product designer, who dreams of working in the industry, you should really check this out. These new Firefly dropouts were machined at Cantabrigian Mechanics and solve the many disc-related problems that have arisen since road bikes adapted the braking technology.

I don’t wanna spoil the fun, so head over to Peter Verdone’s blog for the full story!

    Are these disc related problems purely cosmetic, with a small factor on weight? In all sincerity. These are truly a piece of art but I am missing the problem builders are having.

    • He addresses the issues in his post.

        Thanks for the reply,

        “Disc dropouts for road/cross are extremely difficult parts to design. They need to match the scope and scale of the light bike which is far more svelte than the fat mountain bikes where disc dropouts are most common. The parts need to keep the bike looking like the delicate and sexy machine it is but still mount a caliper well.”

        “The problems with the road disc configuration were solved here by going to a proprietary bolt pattern and adapter piece. This allowed for the dropout to come together without all the problems commonly seen with disks on skinny bikes. The shape of the dropout flows with the frame”

        That is all I am seeing in terms of the issues being addressed. Minus what he says about chain stay mounts. Not trying in anyway to be condescending, honest curiosity if the builder was having issues with cosmetic factors more so than structural. I hope this isn’t getting blown out of proportion. Any incite would be appreciated.

        • I think, what he’s saying here is that disc brake adaption to road bikes has been fairly clunky, when they should be an integrated part of the dropout, rather than a application to a stay, etc. So, I’d assess that these are aesthetic issues, rather than mechanical. Although, I’m sure this system is probably stiffer and easier to setup / calibrate as well.

          Sorry for the confusion! I answered the first reply on the fly while drinking a post-ride coffee. ;-)

    Beautiful solution. Given that a caliper adapter is a part that really never “wears out”, I don’t see a problem with the proprietary mounting location. The traditional IS mounting point is really not any different than this in function, considering all brakes are post mount now.

    Damn, that’s a clean ride.
