The Pivot Trail 429 uses a ZS44 upper zero-stack headset, a 30.9 mm dropper seatpost and a 15x110 Boost front thru-axle, with a Super Boost 12x157 rear.
Pivot uses Super Boost 12x157 at the rear, not 148 Boost, so confirm the rear hub. The bottom bracket is a BB92 press-fit shell, covered on its own page.
