The Anthem X Advanced SL’s geometry is notably progressive for a bike in this travel category. In size L, the low setting produces a 66.1-degree head angle, 460mm reach, 437mm chainstays, 1196mm wheelbase, and 48mm BB drop; the high setting steepens the front end to 66.6 degrees, shortens the stays to 435mm, nudges reach to 465mm, and reduces BB drop to 42mm. Those numbers point to a bike that prioritizes stability and composure more than a traditional XC bike would, especially in the low setting, where the slacker head angle and greater trail figure around 119mm should add confidence on steeper and rougher descents.
The effective seat tube angle sits around 75 to 75.6 degrees depending on flip-chip position, which is moderate rather than extreme by current standards. That should keep climbing posture centered without pushing the rider overly far forward. Across sizes, reach numbers of 415mm (S), 440mm (M), 460mm (L), and 485mm (XL) are contemporary and paired with relatively short 435-437mm chainstays, giving the bike a balanced stance: long enough in front for control at speed, but not so stretched that it loses the quick handling expected from an efficient 120/130mm platform. The flip chip gives riders a meaningful choice between a lower, more planted setup and a slightly sharper, more pedal-friendly configuration.
