- I lowered the seat to where I can comfortably pedal with my heels. However, now I feel that I am not far back enough. I felt a lot of strain on my wrist/shoulders the entire ride and spent a lot of time biking upright. However, I can bike for maybe 5 seconds keeping my body unsupported with my hands off the bars. Is it time to start looking at a shorter stem or do I still spend time tweaking the saddle?
- I have a Zipp Service Course SL seatpost on the way so hopefully that will make adjusting and tuning the saddle easier and more consistent.
When you think your butt's in the right place, put a mirror beside you or have someone watch. With your hands on the hoods, lean forward enough so that your forearms are horizontal and your back as straight as you can get it. In that position, your upper arms should make a 90° angle with your torso. That's how you determine stem length. Oddly enough, when you get that angle correct, your upper arms make almost that same angle with your torso throughout the range of upper body motion.
