What has changed, then?
First, we get a rainbow of pretty colors in the GP 4000S 2:
You see, rumor has it that the S stands for Schwarz – which means ‘black’ in German. Only the magic S-for-Schwarz tires have black chili compound, which is the magic sauce that makes them so darn fast. Now you can have the special compound and black tread, but with color accents on the sidewalls to match your dorky bar tape and shoe covers (yes, I’m talking to you – guy who has to have everything matching the same shade of red). We don’t know exactly how the color is applied, but we’d be very surprised if Conti was foolish enough to do anything to the tires that would increase rolling resistance.
What else is new? Two big things:
1. A new 650x23mm size (ISO 23-571)
2. A new 700x28mm size (ISO 28-622)
In our Fast Tires 2013 article series, we wrote that these two specific sizes were the two holes in Conti’s line. Clearly Continental was thinking along the same lines and saw enough sales potential to warrant making these two new sizes.
Here is a full breakdown of sizes in the new Grand Prix 4000S II:
Finally, let’s talk rolling resistance. Similar to the story I’ve heard from Specialized and Schwalbe, Continental says that larger tires roll faster. Here’s a breakdown of their four width options in the GP4000 S II (Crr on the Y axis, pressure on the X axis):
After a heavy downpour yesterday evening most folks were glad that the 2013 Eurobike show headed inside today, and there was plenty to see. 8.28.13
We examine the world of tires for the 2013 model year. What has changed? Who are the major players? Perhaps most importantly - what is the fastest? 7.25.13
