I currently ride a Canyon Endurace CF SL 8 where I swapped the 90mm stem to a 100mm stem, these are the old stems which run very long, so it’s more like a 105mm stem, no spacers. I run 165mm cranks. I’m 174cm tall, but have a very long legs with an inseam of 84cm, wingspan of 178cm with narrow shoulders.
I’m about to put in an order for a new Aeroad CF SLX in, but can’t decide between XS and S size. Here’s a comparison chart of the stack and reach of my current bike vs. the two bikes I’m looking to buy, but you have to add about 1.5cm in reach to the Endurace due to the non-stock stem. I will also put 165mm cranks on the Aeroad.
Now for my question: what are the differences between going longer vs. going lower? What would you go for if the only real issue is a bit of too much weight on hands indoors?
Ok that’s very insightful, thanks for the link! As I understand it, the Aeroad in S will be shorter (due to the stock 90mm stem vs. 105mm stem on the Endurace), but lower when fully slammed?
Hopefully someone will post it up but there’s a website I used, it’s pretty rudimentary, that overlays bikes as you input the measurements and it will show stem angles based on length and all that stuff based on all the measurements of both bikes. It was helpful for me because I went from a racier bike to a gravel bike, so I wanted to make sure I got things as close as possible.
With smaller frames you run into the quirk that because of toe overlap the front wheel will be in the same place in space, and the reach to the bars is made shorter by some combination of making the head tube slacker, seat angle steeper, and increasing fork offset.
It’s like this one, but for the whole bike. This tool is for Stems;
This one will overlay two bikes;

Uh oh, look at that URL…hmmm. I just opened the webpage again on Chrome (from work so if it was a “bad” website I would have gotten a ding) and that long URL worked.
yea, but when I look at the illustration on top, the aeroad is a bit shorter. So how much can I trust that stack number if the reach number is not accurate? Plus, the stack number of my Endurace is not 590, but 557.
Be cautious, the Aeroad in XS is very low and you may not be able to get high enough to be comfortable. I cannot imagine a bike that small would fit you anyway. The S appears to be better and though the reach is longer you may be able to adjust via stem length. Without knowing more I would also look at a M just exhaust all options. It varies from person to person but I am about a cm shorter than you and no question that a XS or S cannot fit me no matter what I do. If you can get a professional bike fit, it will tell you more clearly which direction to go in.
Lowering weight on bars would require moving seat further back and/or shorter stem and sit more upright, but you mention spending 90% on drops outdoors.
I think most of us would size for 90% on the hoods with drops for sprinting and descents.
