To say the difference between the two was amazing is an understatement. Had run Gators on my old steel bike for decades due to their puncture resistance. When commuting to work, the last thing I wanted to be late for was a flat. So no longer commuting and decided to make the switch and the difference in comfort, rolling resistance and cornering is unreal. The rolling resistance is super low in comparison. I run 5000 TLs on my other bike and love them, so decided to give the tubed versions a try. Wow.
