got my new caad9 5 over the winter as a nube to cycling. Quickly got the hint that I should flip the stem after some research and feeling a bit to upright and really eating headwinds.

Felt like I was in a much better aggressive and aero position. As I am now able to do more miles in the saddle on rides I have found that I do get lower middle back pain after rides. I have been working on my flexibility in general.

Should this go away?

Will core strengthening take strain off back as well?

May want to read up on some fitting articles as flipping the stem has made your reach further. Might have to compensate my changing other things, or refining your technique.

May want to get a fit first then work on your fitness. The fit may alleviate your problems, but it isn't a horrible idea to strengthen your core. I have a relative who races and he is big on having a strong core.

also check some of the online fit calculators, saddle for/aft position can effect how much weight you're putting on your upper body, as well as your position relative to the bb (obviously).

there is no doubt though that if you're new to road bikes, it will be uncomfortable in the beginning. the roadie position is not exactly a natural position and takes some getting used to.

good luck!

Fitness will help. More flexibility will fix it. I did a stupid thing for a race recently. Flipped my stem the day prior. Because of the wind. Severe back pain. Just wasn't ready for it.

I think the suggestion to always "flip it" is just wrong. It depends on the rider, geometry, goals, etc. I know I had lower back pain when my reach was too long, a shorter stem solved the problem.

+1, I had a 120mm stem (came with the frame) and it made my reach a bear. Couldn't even think of flipping it, but now I have a 100mm and it's definitely flipped

the more comfortable you are the more you ride. the more you ride the stronger you get. too many people have their stem the wrong way and you know who you are.......

I quickly found out that I'm much more comfortable on my bike after un-flipping my stem. Do what makes you comfortable on the bike and eff the rest.

I have two road bikes, one with stem up, one with it down. The one with it down has slightly less seat-bar drop than the one with it up, but they are close.

Do whatever it takes to get the right position for you.

thanks for feedback. I was fitted on my bike with ts stem up at lbs when I got the bike. After flip I am going back to have them take another look.
