Congrats on the Ironman, great fast bike, although ton of toe overlap was not to my liking.

As for hoods... I read that some too-strong cleaners destroy top level of old rubber and turn it into goo. Makes sense since each report of sticky hoods that I have seen started with words 'after good cleaning...'. Most interesting recommendation was to re-clean them with Gojo or whatever is the name of pumice 'waterless' hand cleaner. I still have to try that (my project bike with white sticky Shimano 600 hoods is on hiatus now).
Give it a try an report results here!
