The ride felt very good but there were a few problems unrelated to the bike. Previously i had done a century with not one ache or pain so i know it is set up just right. But yesterday I was carrying a backpack which was quite heavy with food and water and shoes and clothes. I had terrible back ache in the last couple of hours. The seat seems to have broken down eventually. There are uneven ridges and bumps and these dug into my bums. the backpack straps dug into my shoulders.
