Trying to adjust to a road bike

[KathiCville]

Yen, I've got much the same problem with feeling like my posture isn't what it should be. I've done three long rides (for me, meaning more than 25mi) in the past three weeks and each time have barely made it to the end because my forearms and wrists were screaming at me. Even when I'm trying to be conscious of not locking my elbows, etc....Yesterday's 33mi was the worst yet.......Had the bike fitted a month or so ago, which helped in general terms, especially with an ongoing lower back ache. But sounds another 'go' at fitting might be a good idea...Plus, I know my core strength is lousy--something I'm starting to work on.....All of the ideas being floated here are really useful, thanks!
