I have a new-to-me road bike and I've got a question: The saddle height and position I have set feels pretty good with the exception of that I still feel like I'm reaching for the brifters. Handlebar/brifter location is great when I stand but when I sit, I have to stretch 3-4 cm past my normal comfortable position to reach them or to ride my normal on-the-hoods hand position. I know that KOPS is a guideline and controversial at that but I'm wondering how you know if you should move the seat forward or get a shorter stem. I'm working on flexibility but have old back injury issues that may limit my ability to simply adapt to stretching out further.
