In the market for a new road bike and I'm considering a Canyon. I've read some issues with their geometry numbers being off. Anyone have experience with this? From their numbers it looks like I could go with a S or M. Small more compact and Medium stretched out. My current bike is a R5 in 54 and before that I was on a S5 54. Which numbers should I be most concerned with? Reach is similar but Stack there is a 21mm difference. Think I'm leaning s but worried it could be to compact, while the m could be a bit long. I have taken measurements from current bike and still fall in middle but that is the R5 so different use. It's set up more relaxed for longer rides. Plan on keeping both bikes. Any help would be much appreciated. Thanks
