Trail
Giant Fathom 29
2022 · 29 wheels · 130 mm fork · 4 sizes
Aluminium trail hardtail with a 130 mm fork, a 66 degree head angle and a 75 degree seat angle in every size. Giant does not say whether its seat angle is effective or actual. Giant quotes 122 mm of trail, about 3 mm more than its head angle, fork offset and stock 2.5 in tyres work out to.
