Key Quotes
What about those of us who just want to catch the Tuesday night local circuit and simply aren’t into shreddy trail-oriented hardtails?

The XTC loves, almost begs, to be ridden with aggression, and it’s in its element when you’re out of the saddle and trying to rip the handlebar in a different direction of the cranks.

Highs
  • Impressively light and efficient, well-rounded racing geometry, durable and race-ready component specification.
