Thanks for the post, Garth. It is a zero setback seat post (not 0 offset). It's a Thomson.
I've measured the setback before on both bikes. I just did it again. Funny thing is the Fargo is 5.4cm setback (tip of saddle to BB), whereas the Roadini is 4.9cm. And, the Fargo has 175mm crank arms vs. 172.5 on the Roadini. And, on the Fargo the saddle is closer to centre on the rails than the Roadini. Yet, when I'm pedaling, I feel like on the Fargo it's more up-and-down (like straight under me), vs. pedaling a recumbent with your feet tracking more in front of you. This is why I mention the idea of swept-back bars on the Roadini. I believe when you're more upright, it changes a lot of angles including while pedaling and the muscles you recruit. Just a theory though! On Friday, August 8, 2025 at 8:28:10 AM UTC-4 Garth wrote: > Jay, In my experience saddle positioning relative to the BB has everything > to do with upper body relative comfort.
