Oh, how I wish there were flat places here.
Yeah, I get it. My priority current was the fastest bike I have experienced. I still miss the speed. Fast in terms of gearing anyway. Even the flx with the insane rohloff range doesn't get up to the priority current gearing. It's still built for low gear mountain biking. The flx makes up for it with a rocketship motor. But it feels different. It's always like there is a nitro booster attached to you. Speed from high gearing just feels more real. Like you are actually pushing yourself to that speed (even when assisted to some extent).
You could put a bigger front cog on the tero too. At that point it will demolish a vado on the plains.
