I think it's important to realize that any change can equal a really painful result. Quick and dramatic changes - such as going from 3-4 cm below to 6 above (not saying that was what happened here, just trying to make the point) - change the stresses on the body dramatically and suddenly. This can be especially problematic if you ride a fair amount already, because, even though uncomfortable, your body is used to a certain position. I know I'm much more sensitive to changes and switching between differently set up bikes when my regular mileage is higher.
My experience has been that smaller, regular movements towards a desired position is much safer on the body. Backs and necks are funny things, and after pretty seriously tweaking mine playing high school football, I've always been careful with position changes. I am very lucky to have been blessed with the genetics of good flexibility. But, in my high mileage years, while also mostly working at a desk, I was definitely taking a "set" - rounding shoulders and back, while my head easily would look up (yeah, I'm a 1 - 3 cm below the bars kinda body/guy). I was lucky enough to connect with an excellent yoga instructor and after 3+ years, have really undone a lot of that collapsing tendency. She also has a strong core focus, and I was again slapped upside the head with the knowledge that a strong core (especially stomach muscles which have NO stress in most cycling) alleviates about 95% of any low back issues. The body is a lazy device, and will only make itself just as strong as it needs to be, and only in the directions in which you ask it to be. ..ok....time to ride! - Jim / cyclofiend.com -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
