    Yes. That thing rocks. Especially the rear 3/4 view.

    I love that you are building stems too. Makes the whole bike more complete to me.

    EQUILIBRIUM Pegasus disc road bike's ride impression :

    Time passed from NAHBS and I had a chance to have a test ride on my latest road disc brake bike “Pegasus” .

    Building a show model bike was good opportunity to think out of the box and try something new , to experiment with materials and construction . In that regard I chose to use as large diameter tubes as I could find on the market to see how stiff things can get and what influence it has on riding quality .

    First of all I wanted to build a allrounder bike that capable to handle different situations , road/off road , long distance riding , nevertheless it has to be as fast and responsive as a proper racing machine .

    By choosing lower bb hight 75mm and slightly longer chain stays 415mm and trail of 58mm
    the handling was nailed to perfection , outbalancing the stiffness of materials giving a reasonable flex around BB area .

    Curved stays played it role as a rear suspension increasing the comfort and traction of the bike , especially when road condition wasn’t perfect at all it glided smoothly over the surface . The rear wheel stayed glued to the road in very tight turns and tricky spots
    without compromising stability and balance .

    Another thing that pleasantly surprised is how fast I could get on the bike and holding very decent average speed and still staying in my comfort zone over prolonged period of time , seemed the bike responded better to a heavy ratio 52/15-14 at a 85-90 rpm on the flat sections .

    Overall performance passed the test for the racing machine with extended usability .

    Although I am only speaking from the pictures, gotta say you've produced something so thoroughly modern from traditional materials that really makes me want to know more, are some of the gussets/buttresses an attempt to incorporate aero considerations to the frame.? Is it significantly heavier than a 'traditional' brazed frame?

    Love the dropouts and the transition of stays into them, the 'flow' of the lines looks particularly attractive.

    Looking forward to seeing where this design takes you......

    Would love to see photos of your NAHBS frame during the brazing & building. Didn't find them on your flickr page. Truly wonderful stuff!

    Thanks a lot for your interest ,

    The gussets indeed is my quest for aerodynamics and increasing rigidity of the frame ,
    however I had no chance to test the bike in in a wind tunnel but believe it or not it felt like moving with it's own inertia , undisturbed at higher speeds .
    Regarding the weight all shaping added less then 100gr , the total weight is 2.1kg frame only , for comparison Columbus Max fillet brazed frame with 44mm Paragon head tube
    would weight around 2 kg .

    For sure will keep investigating the matter and keep on updating .

    Sorry I was too busy to take any pictures , I finished my other show lugged frame just right before I had to leave to airport .
    I have a number of aero frames to build in a near future , I promise they will show up in a building process on my Flickr and here on the forum .

    I saw some photos of the process on your flickr, looks like you there's some steel to give a rough shape and then some sort of sandable filler over top.

    I'd be curious what the filler is and how thick you're applying it, I understand though if it's a "secret sauce" sort of thing though.

    I'd reiterate what Corko said - for me this was one of the most interesting frames I saw in all the photos I went through coming out of NAHBS. I had the sense that the shapes, arcs and fill-ins had a functional purpose, not just ornamental. Your write up confirms that. It is a really striking looking bike. I look forward to more detail on your developments as you make additional models.

    There is no "secret recipe" really , I suppose any kind of two part epoxy filler that sticks to the metal will work fine , the ones meant for the aircrafts
    will be the best choice cause they made to withstand the flexion of the structure .
    First of all I do reinforce all the joints by the tubes or plates to prevent any load on the filler , so it has cosmetical purpose only .

    Jorn , thanks a lot for your appreciation .

    It was scary as hell to go outside the traditional forms , could end up with tons of man hours wasted to build something with no meaning but after
    the first test ride I didn't regret any single minute spent on the frame .

    Curious for more insight about the effect of the curved (convex) seat stays you used on the NAHBS frame & a few others. I've read David Kirk's take on his terraplane stays and recently came across the Dedacciai Adamantis tube set with a similar bend.

    Beyond the aesthetics, are there riding conditions where you prefer them?

    apologies for the poor image quality

    There is no doubt curved ( convex ) stays work very well as a suspension , increasing the rear tire contact with a surface , instead of hoping
    over the bums , small cracks , stones , sand , etc. bike stays attached to the surface without loosing the traction - it gives a very smooth ride
    and confident handling also the bike will go faster , same effect as having wider rims with a slightly lower pressure tires .
    Another application were I noticed a difference was a climbing , in and out of the saddle , seemed like the stays by the vertical flex gave me a push to go uphill.
    Overall having a softer tail to my mind is an absolutely win - win situation .
