Wanted to get some opinions.

First, I'm 6' tall and have a 33" inseam. I was previously on a Large Wilier Izoard (557 top tube and 160 cm headtube) with around 3 cm of stack under the stem and running a 100 mm stem. I feel like I could have gone a bit lower and possibly needed a 110 stem.

My question is, I have the opportunity to pick up a Le Roi but in an XL size (570 top tube and 170 headtube). Looking at the numbers, I feel like it actually might be perfect. I could run a 100 mm stem with no stack and be right about where I was or wanted to be before, right?

Would love to hear some thoughts!

The Large Izoard has a STA of 73.5 while the Le Roi has a STA of 73. Both have a 73 head tube angle.

Will that have that much of an affect on reach? I'm not worried about the stack. I feel like with the 170 HT on the Le Roi I'll actually be able to run almost zero stack hopefully, which is what I was shooting for.

The reach is the only thing I'm even marginally concerned with. I wouldnt want to run anything shorter than a 90 mm stem and given the numbers, I think a 100 would be about where I would need to be on the Le Roi. Depending on what bars I run and the reach on those.

What do you think?

How did you come out to that number? I'm not doubting you, just wondering for my reference.

Could I also just play with the fore aft position of the seat to make up for the 8 mm difference? I had a set back seatpost on the Izoard. Would moving to a zero set back post be a better idea?

Appreciate all the insight by the way!

I'm confused.

If the Izoard is at 73.5 and a 557mm virtual top tube and the Le Roi is at a 73 and a 570 virtual top tube, how does that equal out to 8 mm difference according to how you calculated the change? Wouldnt the .5cm (half of the 1cm for every degree of change in STA) need to be added to the 570 since the 73 is more slack then the 73.5?

I probably am just understanding this completely wrong.
