I can thoroughly recommend the Anthem X4. I have an upgraded X3 and, after riding my X3 a few times, my wife replaced her bike with an X4. Giant’s Maestro suspension system really seems to suit the short travel of the bike, and the geometry is excellent – quick and precise handling, but not twitchy. Given that it’s race derived geometry, it’s an incredibly capable bike. Obviously, you can’t straight line the sort of terrain that you might on a long travel trail monster, but it’s brilliant for UK trail centres – I’ve also taken my Anthem X to France a couple of times, and if you have a modicum of skill, it’s amazing what the bike can do.
It’s really easy to dump a load of excess weight from the X4 by upgrading the wheels – this also perks up the handing and acceleration no end.
HTH
p.s. I bought mine after demoing one at a XC race. Top tip from the Giant team mechanic was to go for the smaller size bike if you are on the borderline between sizes – ‘cos on some, like Med-Large, the jump in frame size is huge. I’m 6’ and after trying both Large and Med, I went for a medium and have been v.pleased with it.
