Need new bike suggestions. Am 40+ 90kg and currently riding a 9yo hardtail twice a week around Terrey Hills. Wanting to increase my Mtb fitness/skills etc and need a new bike. Any thoughts on the Giant Anthem X1 2011 26". Budget $3000. Want to do Northern beaches trails (typically perimiter, long, ryland, sandy, centre, chiltern, duckhole + any single track) for training and aiming on XC race (intermediate level) and adventure racing. Any suggestions welcome. (N needs to equal 1 - I'll worry about +1 later).
