Thanks all for the help... swapped the rear and placed it up front. Ditched the front Gripton S-works tire and found a lightly used 23mm Gatorskin my my closet. I'll be good to go. Word of advice with these Specialized S-Works Gripton tires. Don't train on them like I did. You'll pick up lots of road debris that can give you hairline cuts in your tire. Use it for race specific events. I only raced on this once this season but kept them on my bike during our group training rides and solo training rides. To bad as I only had them for a couple months.
