I'm curious  about the seatpost-I'd like a zero offset option, but upthread tantan told someone that an actual sl8 seatpost doesn't swap in...

I'm 5'-10" to 5'-11", inner leg length i would say is normal. I've always run size 54 bikes (cervelo, giant, scott), so I'm expecting this to fit similarly. You can use BikeInsights.com to compare frame geometry's. I compared my now old Cervelo R3 to the SL8 (TTX68 is exact same geometry), and found 6mm more reach and 11mm lower stack.

Thanks, same length here (but in the normal metric system ) Also on 54 on different brands (or S in case of canyon).

I'm also eyeballing a different crank/powermeter. Not sure if everything fits on this frame. Which combi Xcadey/Lexon are you considering als an future update?

Likely 170 cranks as i have that on all my bikes. Don't see any 5 bolt 130bcd options, so probably going to go with their 4 bolt 110 bcd and their 54/40 chainrings. I'd probably go with the 24mm titanium spindle as well, for compatibility and availability of BB's across the different shell sizes.

Cool build for the weight and price - just fire!
Tell about the feel, how well the bike rides, how stiff is the frame? What branded bikes can you compare it to?

I won't get a good feel for this frame until spring, as i'm parked on the trainer most of the time. Just spinning it around the neighborhood for 5 minutes, the ride is nice. I'll have a better feel for the ride and stiffness in a few months. I'll be comparing this frameset to a 2014 cervelo r3, winspace t1500 (in progress trainer/ crit bike build), and previous aluminum scott speedster (tractor of a bike compared to the ttx68).
