(disclaimer, FTW builds lots of bikes for my brand, Spooky, and these intial protos are heading to Spooky's new shop in NYC, I also work out of the back of his shop)
Tiemeyer quit making frames earlier this year. Everybody we've talked to said they were totally radical, so we wanted to make sure we made something that was at least as awesome.
As I'm sure you know the design features of those frames go all the way back to the mid 90's with the GT frames. In fact, the dropouts, seat-tube and seattube topper on your bike are left-over extrusions and forgings from the GT days. As far as it's been related to me Mr. T ran out of parts, so he quit making the bikes.
Frank actually cut up a Tiemeyer while he was putting this thing together: Structurally this bike is completely different but: these dropouts DO use the same inserts as the dozens of Tiemeyer and GT frames out there(because it's the best way to do it).
Basic tube specs!(all custom drawn/tapered and/or butted in Connecticut and hand-formed by FTW in VT):
tt: custom butted swage/tapered single-oval double-butted tt
41.6mmx34.6 to 35mm round
48.6x70.5mm penta at headtube to 76.5x30.7mm airfoil to 70.2x45.75mm penta/D shape at bb shell
76x32mm aero profile shaped to 52x49mm with wheel slot cutout at BB end, penta/D shape at BB shell
weld-in 25.4mm seattube stub with internal reinforcement
custom tapered/butted/formed 1.125" chainstays
SS: 12x25mm compact seatstays
custom CNC machined S.H.I.S. 34/56mm tapered setup for 1.5--->1.125" steer tube
44.5 to 62mm external taper for Serenity 35mm rake tapered fork
custom cnc 9.2mm wide double-shear double sex-bolt interface, 5.4mm wide replaceable steel inserts(use the same interface as existing Tiemeyer/GT).
Essentially, besides the fact that the tubes are pretty dang big on both bikes they couldn't be more different!
