  • As deep as the shit render? No.
    As deep as the one of which we've seen photographs? Obviously, and nobody questioned that.

    Wrong. Even in steel, 953 is substantially stronger than 853.

    Wrong again. The main determinant of practical frame stiffness is torsion in the down tube, and for that a tube of circular cross section simply can't be beat.

    52mm deep to be exact. The one in the photographs is 48mm.

    I'm not an expert like you are.

    This is the input I was looking for. Thank you.

    853:

    UTS: 1250-1400 MPa, density 7.78 gm/cc

    953:

    UTS: 1750-2050 MPa, density 7.8 gm/cc

    The strength is a lot more. They don't have stats for Aero tubes.

  • Is that a Titanium spoke?

    This would not support the weight of a standard "coat" if it's just stainless.
    I know, I have tried...

  • Hmmmm I do have a cracked zipp at home with bladed spokes. this could work

  • My 2p for what it's worth. Nothing wrong with that 14 Bike Co frame. Not my cup of tea, but it's always good to see others designing and building frames, and contributing to cycling in a positive way. Even if it's not something I would want to buy, I applaud the effort.

  • since when is black associated with leader bikes?

    I realised my comment is pretty vague.

    I suppose it would be more accurate to says that matt black aero-style track bike doesn't look appealing nowadays after seeing the mass of similar track bicycle coming out of Taiwan, specially when I first saw Andy's bike, I thought it was just another Leader jobbie.

    Thank you for going out of your way to make such a remark. This is a rare and kind gesture. I'm proud of this frame.

    The truth of the matter is that cheap 4130 Cr Mo is plenty strong enough for a track frame, and making it in ⅛" over the old 1930s standard tube diameters will make it stiff enough for anybody who can't put out over 2kW in a sprint. The thing that nobody has ever got close to with steel is combining stiffness and aerodynamics to the degree that carbon fibre frame makers can, which is why all elite track riders use carbon fibre frames.

    If you actually think those 'teardrop' 853 tubes represent any kind of aerodynamic benefit over round tubes, you need to go back to aerodynamics school too. For all your bluster about 20 years of genuine technological advances being all marketing, the actual facts point to so-called 'aero' steel tubing being the thing which has the greatest excess of hype over substance.

  • I dont really have much of an argument for or against the technology or design of bike geos to give any weight to this argument as i just dont have the knowledge. but i would much rather give a bit of support to a small british brand/company/group of people doing things a little bit different than the norm and see what they come up with. it may not be the best money can buy. it may not be be the best value for money but i'm gonna wait to see it before making too many judgements. most of you guys will have a far deeper knowledge than me on this matter but for fuck sake can we give a chance before it gets hated on. of course this is all about people opinions and you are all free to have them and express them but fuuuuuuuck. c'mon.

    I had a Louis Garneau Pursuit 9.0 in 2007 that was all matt black, the thing was very thin, light and stiff. This was way before Leader bikes were on the scene.

    I know it seems not as relevant to you Ed, as you have progressed onto touring bikes quite rapidly. I do remember a time not so long ago when you were coming into 14 bike co and getting parts for your Bob Jackson fixed gear bike. Just because one person's taste changes, it does not mean that everyone's taste corresponds...

  • metallurgy school.

    aerodynamics school

    are these state or private?

    Tell it to the world please. I know all this.
    I'd still prefer a Steel Aero frame over an Aluminum one. Carbon is out of my price range.

    Again, you think I went to Aero dynamics school?!

    None of these factors you have detailed above have any relevance on the average rider of a fixed gear bike on the street. Which is who this bike is aimed at. People like me.

    You should go back to the school of chill out.

    Your knowledge of the technicalities concerning bicycles is unquestionable on this forum. You don't need to prove your point on every damn thing that comes up...

    Your knowledge of style has yet to be proven though...

  • are these state or private?

    More importantly - are those boarding schools?

  • snow boarding?

    I could teach you that Kris....

  • Why matt black?

    Where can I see the geometry of these bikes?

  • Carbon is out of my price range

    O rly?
    http://www.planet-x-bikes.co.uk/i/q/FRPXPCTV2/planet_x_pro_carbon_track_frame_new_logo

    Considerably cheaper than your 853 frame.

  • I'm gonna get myself one more of these.

    As I said, your style has yet to be proven...

  • andypancake, you deliver some amusement to the masses tonight, well done

  • Yes, he really is jokes

  • andypancake, you deliver some amusement to the masses tonight, well done

    I have not changed since I joined. I have no idea what you mean.

  • I'd rather read jokes and the non aggressive postings of Andy than watch other sanctimonious types blow hot air up their own arses.

  • Your knowledge of style has yet to be proven though...

    oh i beg to differ...

  • No waaaay man! =)))))
