Strengths: Fast, direct, well behaved. I bought the frame and built it up with my own kit. In my view it needs 100mm forks up front, this tweaks the geometry, makes for a more relaxed pose and gives it an air of invincibility.
Weaknesses: Lots of bushes and bearings, that said I've raced mine for a year and it's still holding up.
Overall: This is by far and away the best XC race bike that was produced last year. Heartily reccommended.
