Ten days ago I reported that I was replacing the tires on my mountain bike with Performance Topo FasTrac MTB Tires, a semi-slick tire that I found on sale at Performance Bicycle:

Performance Topo® FasTrac MTB Tire (Folding) Introducing the new Topo® FasTrac ATB Tire Even faster and lighter than our SemiSlick+! Features cornering knobs strategically made shorter and spaced more closely together for super-smooth transitions into corners, and center grooves that add serious traction. Highest quality 120 tpi casing. Folding. Blackwall. 26x1.90. Wt: 495g.

The Topo FasTrac Mountain Bike Tire reminds me a lot of the Ritchey Speedmax tires that are installed on my wife Kathleen's mountain bike. The biggest difference is that the tires are only 1.9-inches wide rather than 2.1.

I thought the Topo FasTracs were easier to work with than many other semi-slicks I had installed before. They were flexible enough to go on my Mavic CrossLand wheels pretty easily. I rode up and down the street a couple of times to make sure the tires were properly installed and inflated, but I didn't have much of a chance to see how well they performed. I'll try to write a follow up article on that issue after a week or two of riding.
