I checked with some of my Officers today and they also recominded the toupe gel in the 130mm and or the 143mm. I am 53 yrs, and ht, 5.6, wt 130. with diabetes, I have lost 45 pds, with diet and bike riding. I have a few bikes but I got a new caad9 and had it fitted by a pro, I have put 350 mi, on the bike and the doctor wants me to go from 60 mi, a week to 100. a good fit is a must i have to really watch the sores. This weekend I think I will see if they can fit me with one. THANKS.
