“LHT.
TT=.8x.5x.8 at 31.8mm
DT=.9x.6x.9 at 31.8mm
ST= 1.2x.6x.9 at 29.8mm at the seat tube and 28.6mm at the bottom
bracket
Stays= .9mm
Fork blades= 1.1mm to 1.4mm tapered

Check.
Top Tube – 28.6mm dia 0.9 – 0.6 – 0.9mm thickness
Down Tube – 31.8mm dia 0.9 – 0.6 – 0.9mm thickness
Seat Tube – 29.8 dia at seat collar, 28.6mm dia at bb 1.2 – 0.6 –
0.9mm thickness
Stays – 0.9mm thickness
Fork – 1.2 – 0.9 – 0.7 thickness

Worth noting also the TT on the LHT is not a constant profile and is shaped at the ST and HT.”

That’s from a random Internet thread but the Crosscheck ones seem right (I have a CC but not an LHT)
