Yea if your hitting pegs on the xc it's at it's tires limit and just a sneeze away from a bad situation. Having done a track day or two and raced MX for too long the my op on the 21" front is that it is nothing short of uninspiring and wants to run wide searching for the side of the road. It pushes and squirms when put to task big time. Great off road love it ! On road, I would never push it to the point of scraping pegs, just asking for a bad ending.
