Another upgrade I did couple weeks back. My Comp Carbon shipped from the factory with Specialized Espoir Sport 700x25 tires. They actually rode nice, no real complaints. However tires (on anything, bikes, cars, etc) are always something I like to try different things. Back in the day I raced motorcycles and Michelin slicks were one of my favorite tires to run. When I came across the Michelin Pro4 and read they used trickle down technology and rubber from their MotoGP tire I had to try it. Enter the Pro4 Service Course.



I've got almost 200 miles on them now, and really pleased. Ride is plenty comfortable, rolling resistance (overall speed) was noticeably faster. However the biggest difference I felt was fast cornering, the Espoir were not confidence inspiring. The Pro4 reminds me my old race bike on Michelin slicks, lean it over in the corner and it's locked in throughout the whole turn.
