Description
Transition Bottlerocket – Built for Freeride, Bike Parks, and Downhill
The Transition Bottlerocket is built for riders who want to push their limits, send bigger jumps, and take on the most demanding freeride terrain. Designed for bike park laps, downhill tracks, and creative riding, this aggressive alloy platform combines long-travel suspension with a durable construction built to handle repeated heavy impacts.
Available in both single-crown and dual-crown configurations, the Bottlerocket adapts to different riding styles. The single-crown build features 180 mm of front and rear travel, offering a playful and versatile setup for freeride lines, jumps, and technical trails. For riders looking for a more downhill-focused machine, the dual-crown build pairs a 200 mm fork with 203 mm of rear travel for increased capability on demanding tracks.
The frame features a robust forged rocker and chainstay yoke, designed to improve stiffness, minimize rear-end flex, and maintain smooth suspension movement. Additional bolt-on downtube protection helps guard against rock strikes and shuttle wear, while the gravity-cast bottom bracket area provides strength and precise alignment.
With adjustable geometry through the C.H.I.P.S. system, compatibility with a 29″ rear wheel, and two complete build options, the Bottlerocket provides the perfect foundation for riders who want a dedicated freeride machine without compromising on durability or performance.
