Mark Elssaser- Elk or the Elssassinator. Probably the most soft spoken and reserved of any of the riders in this elite group. On any given day in a traditional distance race, Mark as proven himself to be a tough guy, but in endurance races, Mark really shines. 2004 Single Speed National Champion for 24 hr racing, 5th in the worlds. At a cross race this fall, I knew my Spot Brand teammate was cheering for me because he was the only one yelling "you're weak, you're not suffering enough" I am scared to imagine what goes on in his head for 24hrs. Mark was 2nd in the Monster Michaux as well. A co promoter of the Philly single speed rally the dude is tough as freaking nails. I have heard rumors that the guy gets up early so he can get 4 hours on the bike before he goes to work. Methodical in approach, a machine to race against. Mark has been single speeding for a long time, and is the dean of mid atlantic single speed racers.
