  1. hi to all anyone here is experienced with the 2x700c t-bone? i'm on the way to build an highracer,
    with a local little df bike builder we starts to think about a 2x650c drawings, but we also likes
    700c option (more tire choiches, especially on the diamond frame bike country, i.e. italy ;-) using
    a standard roadie bike frame tubes, i can keep the seat slower than a monotube frame type frame as
    bacchetta, but the major issue for me is the seat/bb height difference, and if a higher bb with a
    lower seat may be unconfortable using the bike for relaxed altough fast rides the t-bone is a
    really good looking bike (imho) but i'm wonder if the riding position will be good only for racing
    thanks! mate

    I used to own a Reynolds Weld Lab RT [1] with a 33 cm seat height and a 66 cm BB height. The
    reclined seat and high BB will make starting, stopping and low speed handling more difficult. The
    higher seat with dual ISO 622-mm wheels will aggravate the starting and stopping issues.

    Numb feet and foot pain may be an issue for some riders with a very high BB relative to the seat.
    For me, shoes with adequate with and very stiff soles (Sidi Dominator II Mega [2]) were a
    requirement for riding the bike, as were clipless pedals.

    The Reynolds Weld Lab designs are best suited for riding fast on the open road - other aspects have
    been compromised as necessary to optimize performance.

    [2] Also sold in Italy, I suspect. 😉
