    Another custom AMHT frame

    Hi guys,

    I recently received this pic from the factory where my frame is being built.



    There's still a few welds to be done (rear brake tab, cable stop, hoses guides), some sand blasting and it will be good to go.

    For those of you who want some figures, here they are:
    600mm top tube effective lenght
    425mm chainstays
    44mm ID headtube
    74 seat angle
    67 head angle
    Will take 160mm travel forks.

    And yes it's titanium and the down tube is hydroformed. Hope you like it.

    No it's not top secret. It's TSB.

    64 degree servant tube angle?
    Sorry I made a mistake. It's 74.

    That looks really good. Would you mind sharing details on cost and design coordination?

    Also will be interested to see the tire clearance. I've owned 5 AMHT's now, and limited tire clearance was the reason I sold the first three. It seems like a 73mm BB shell, and segmented chainstay(s)- are the most common ways to get clearance for 2.35"+ tires in conjunction with shorter stays.

    Well, total cost will be around 1200-1250$.

    I did the design but had to change it a bit. I absolutely wanted both top and down tubes to be bent. At first I designed the frame with 44-45mm OD top and down tubes. I asked several frame builders (Triton, RTF, Ora, Hilite) and they declined, didn't answer or tried and disappeared. Those who declined weren't able to bend such big tubes in a conventionnal way.
    Among them, only TSB answered favorably. Please note that I didn't get in touch with XACD because of some apparent quality problems.

    TSB couldn't bend the tubes I required so the top tube is now 38.1 OD and the down tube is 48 OD at the head tube. They use that tube in other frames so it's been quite easy to get it for mine.

    A 2.4" tyre should fit.
    You're right it's a 73mm BB shell. Tyre clearance was a concern here. I didn't want to increase chainstay lenght just to fit big tyres more easily. Wheelbase is already long enough with 425mm chainstays.

    No it's a standard 135mm rear axle. I wanted some removable dropouts at first but chose to keep it simple in order to lower the total price.

    Love it!
    Thanks a lot.

    The frame is now finished and on its way to my home.
    I forgot to remind them that I wanted it sand blasted but it looks good this way. I guess I'll keep it as is.

    Great looking bike. The lines are unique, which I dig.
    26 inch wheel I presume.

    I will braze my own this summer at UBI. Gonna have low BB, slack HTA, short stays, 650b wheel, and 150mm fork.

    Wont be as pretty or light as yours though!

    Your bike need a Pike, matching Reverb, enve wheels, 1x drivetrain, and XTR brakes.

    Mmkay? Thanks.

    No, it's not built yet.
    Actually I had to send the frame back because the brake tab was bent (it moved slightly after welding).
    It's repaired now and should be sent again to me in the upcoming days.

    That's something to talk to a custom builder about. My frame has 420mm stays and can clear a Conti 2.4 just about. All without any fancy machined bits too, just bent tubes and carefully placed bridges.

    Agreed, I can clear a 2.5 tire with zero machining as well. After 5 frames one should have a good idea of likes and dislikes. Time to stop wasting money on frames and have one built to the riders spec. Then again, some people change bikes more often than their underwear.

    Thanks for all your comments guys.

    The frame arrived yesterday.
    I just fitted the rear wheel to see if a 2.4" tyre fits (Maxxis Ardent) and... it's ok.

    I'll build it over the next weekend and post pictures once it's done.
