WhyFi , the stem length on the Helix is 110mm so you were just about spot on regarding my fit on the Helix. Even on my SBC 6061 which is a 58 (for some strange reason, they skipped 56 and 54 would’ve been way too small), I had to go 0 setback on the Seatpost and -17 on the stem. Luckily, I still had a carbon 0 stack height top bearing cover to get my fit just right on this 58cm frameset.
Beautiful afternoon ride today.
