Wife of 44 years gave me the option of 2018 Roubaix Expert electronic or mechanical. I chose mechanical to save her a few $$$. Really don't see a need to spend the extra $$$ since I'm not a HOT SHOT RIDER, just a 67yo fogey registered for 2018 Bike Sebring 12/24 Hour RAAM Qualifier. Just a 400 mile TT in 24 hours.
