Just thought I'd share my first impressions after replacing tires.
I chose the Forte Pro Kevlar (Performance Bike) over a replacement set of Conti Gatorskins. One advantage was that the Forte's are foldable & I could get them home easily on the bike (12 miles). They were also about $5 cheaper apiece. I also fancied a change.
First impressions are very good. The ride is extremely smooth, comparable to the Vittoria Rubino Pro tires on my "best" bike. In comparison to the the Gatorskins (a bit harsh, but very hard wearing) there seems to be noticably less rolling resistance and improved comfort - whether the Fortes can compete in mileage, only time will tell.
