No that's not an extra stud. Little bastard gave Evil a flat. I haven't been on Evil since Saturday, so he must have picked it up then. Noticed the airless rear the second I got on so at least I was home to repair it and not out in the middle of the dark.
Evil felt good. The Beast is great and can handle all that an urban winter can throw at him, but with temps in the 40's and the trails clearing up some, plus Evil has full fenders, the ride was a little closer to road. 20/11.9
