    Do NOT buy a new aerodynamic bike of any kind any time soon

    Looking for an aero road bike? Looking for a TT bike? Forget about it, save your money, it's all about to change.

    UCI set to scrap '3:1 rule' limiting aero race bike design - Cycling Weekly

    “The 3:1 tube rule is gone. At the [World Federation of the Sporting Goods Industry] WFSGI UCI committee meeting on Tuesday it was decided that the rule would be dropped.”
    A UCI spokesperson provided the following statement: “The UCI Management Committee recently approved the removal of the specific clause in its Regulations relating to profiles in frame construction. The amendment, entering into force in January 2017, will have a marginal impact on frame design. But it is important that our sport embraces innovation and evolves with its times.”
    Marginal? Ha ha.... no. This is beyond marginal.

    We just don’t realize the most significant moments of our lives when they’re happening
    Back then I thought “well there'll be other days”

    There's sometimes a buggy.
    How many drivers does a buggy have?
    One.
    So let's just say I'm drivin' this buggy...
    and if you fix your attitude you can ride along with me.

    If a car hits you riding that... They were aiming for you.

    It's not very likely that we'll see any bike designs that take advantage of this change for as long as 2 years and if/when we do, it'll probably be limited to TT products initially (think broad fork blades). Bikes will still be conventional diamond shape and the real aero opportunity is getting rid of elements that don't need to be there (seat stays, top tube or down tube).

    Seems like this will mainly result in larger logos on bikes.

    There is already some Tri specific bikes that exceeded that now invalid 3:1 rule. Look at the Felt IA series for an example.

    Not sure that would make a great road bike frame though for a profile like that. But you could start seeing these in TT stages though.

    Good point. This may be the big advance in logo technology we've all been waiting for

    The race is on, be sure of that.

    And many of these companies could possibly have had a design or two stashed just in case this happened.

    Bigger logos? You know it.

    The rulers of the market will do ANYTHING to create demand and make the consumer feel their existing equipment is inadequate. You can bet the manufacturers had a hand in pushing for this rule change.

    Yea, and just look at the new ridiculously low rear tire pressure standard. Low is fast and this proves it!

    I 'get' disc brakes for those that do type of rides where they can benefit from having them.....but who in the world is doing that type of riding on a bike like that?

    Diamondback was pretty straight forward about it. They said the discs were easier to work with, so they went with them. They said it's easier to hide them from the wind vs. caliper brakes and it gives the wheels the freedom they were after.

    Unlike most bike design projects, this one started with the wheels and considers the wheels to be the most important part of the whole unit.

    I don't think they're claiming disc brakes to be the end-all, just much easier for them in this particular application.

    Pretty radical bike.

    Sounds like a marketing departments way of saying "cheaper to make" to me. I'd be shocked if disc brakes, no matter what, are more aero than hidden calipers but I suppose I might be wrong about that.

    One thing is for sure, most all manufacturers seem to be pushing disc brakes.

    The UCI is letting them back in next year provided they round off the edges. Hope and Sram already have it setup and Shimano said that yes, it would of course comply with the request of the UCI and release rounded over rotors by next year.

    They're being pushed on all fronts; road, gravel, TT, everything. They have a new and now widely adopted standard for mounts, hub spacing, the whole thing. Well not through axles yet.

    Mavic seems to have the best idea? It requires proprietary dropouts though, which is a huge adoption to make. Will they be shunned like the SCS idea was? Because dropouts are frame design related this one last detail has to be sorted, and pretty quick too. It's either a go or a no but a dropout and TA standard needs to be adopted and that will be the final piece to the current puzzle.

    From here it just gets more into the rabbit hole. Fairings over the calipers, aero spiders/carriers for the discs themselves... the redaction of the 3:1 rule might just make them invisible to the wind soon enough, who knows.

    I'm a rim brake guy but it's not looking too good. Damn, talking about damn disc brakes again.

    This was conceived long before the UCI 3:1 discussion. Even when that rule lifts, unless they do away with the rule requiring seat stays, that won't go. Neat design though, great to see someone going outside the lines.

    Don't tell anyone but there's rumblings that they're not really going to fully lift it. Instead maybe move to 3.2:1 or something. But you're right on the seat stays, there's that. This bike's doomed most likely for UCI, but that's their intention anyway.
