    Sub1.9 kg tt59cm mid90s steel frame ID?


    If anyone knows what this frame is and could help me identify it, I would be most grateful.


    Distinctive (or not) details of the frame:

    (1) Seat tube top - is concave, curved in.
    (2) Rear brake cable routing - brazed-on noodle on the seat tube.
    (3) Seat post binder bolt - is behind the seat tube.
    (4) Top mounted cable routing - the shifter cables and the rear brake cable are routed along the top of the top tube.
    (5) Head tube - the reinforcement rings.
    (6) Rear derailleur cable braze guides - are under the seat stay.
    (7) Ritchey rear dropouts - incl flat (vs round) seat stay and chain stay ends & eyelets.

    - Weight (approx.): 1.886 kg
    - Steerer: 1 1/8 inch
    - Seatpost (approx.): 26.6 mm
    - BB (British): 68 mm
    - Dropout spacing: 135 mm
    - Top Tube (approx.): 590 mm (c-c); 615 mm (effective); 28.6 mm (diameter out)
    - Seat Tube (approx.): 435 mm (c-t); 390 mm (c-c); 28.6 mm (diameter out)
    - Head Tube (approx.): 110 mm; 36.5 mm (diameter out)
    - Down Tube (approx.): 32 mm (diameter out)
    - Chainstay (approx.): 420 mm
    - Reach (approx.): 460 mm

    Serial Number: B99XXXX (B plus 6 digits)

    Other (Ir)Relevancies:
    - Came equipped with a threaded 1 1/8 inch triple butted (TB) rigid Kona Project 2 (P2) fork.
    - Originally from Germany.
    - Preliminary discussion: ID: Sub 2kg mid 90s steel frame - with TB P2 but not Kona? | Retrobike.

    Close matches so far:
    - Many Scott mid-90s models.
    - Biria MX 700, but round seat stay and chain stay ends and 27.2 mm seatpost.

    All input appreciated, any ideas or suggestions are most welcome.

    Could be a Brodie? Though there are people on here much better at this game than I. Cheers and nice looking frame.

    Brodie is a good guess. The noddle around the seat tube says "British Columbia" to me.

    It is for sure no orginial, i.e. handmade Brodie (the frame number does not match) - but maybe some later modell of a taiwanese production:
    Otherwise, the noodle would point to an earlier year?
