very cool.. what cassette do you use on the Wheeltop?
Update after ~50 miles on the bike. Using a 46t pass quest chainring, on a pes515 power meter crank set, with the ztto 11-46t cassette. Shifting is great and faster than my Shimano 105 di2 on my other bike. No issues with 13 speed setup, while running a dura ace 12 speed chain.
Overall super happy with the performance, the 11-46 cassette has tight spacing and feels pretty workable for a road bike even. Will probably throw on a 11-52 for steeper routes.
Frame feels very durable, but is very stiff and not particularly compliant. Fine if your running 50mm wheels, but it definitely feels harsh with 40mm g-one rs tires. Not too big an issue for $500 dollars, but definitely not the same as top of the line gravel frames out there now.
