oh no.
Currently im happy with my tt912, though its kinda heavy.
Really looking fwd to someone who gonna build it, n get the estimate weight.
Once Ltwoo/wheeltop comes out with satelite shifter for Tri (i also do consider sram apex xplr axs 12speed 1x +blips n mash with shimano HG setup, but market still expensive for these), i might build another Tri bike (n size down to drop weight)
