    I’ve been a Continental 4k, 4kS, and 4kSII fan for several years. Just put a set of these (700×25) Inertia’s on my carbon roadie after getting a sidewall blow-out on my (700×25) Conti’s. They way outperformed what I expected! The grip on corners was unmatched—which is what Conti says makes theirs faster. Plus, the ride comfort was smoother too. So, I put a set on my wife’s bike and she loves the ride too. We both think that they are faster, but can’t confirm. Could just be riding faster because we like the way they feel.

    Update: Have now ridden these over 1,500 miles still with good grip and no flats!

  3. Mark Solow

    Update: Over 3,000 miles. Still round. Still decent grip. Still no flats. Amazing! Unquestionably the best tire I’ve ridden in the 10 years I’ve been riding 5-6 times a week!
