One of the most iconic names in mountain biking is back with a bang! The all-new Bottlerocket is a 27.5 specific bike suitable for park and freeride. Two completes and a frame are available; a 200mm pure park build with a triple crown fork, or a more pedallable 180mm version with a dropper post and single crown fork.

Transition Bottlerocket Adjustable Chainstays

Standard chainstay length can be increased by 5 or 10mm length thanks to the replaceable SALSA chainstay length adjusters.

Transition Bottlerocket CHIPS

CHIPS Shock progression and geometry adjustment can alter the bikes head angle and progression independently.

Transition Bottlerocket Gravity Cast Bottom Bracket

Gravity Cast BB area, adding strength to the BB and main pivot area and precise shock mount alignment for the new CHIPS shock pivot.

Transition Bottlerocket Forged Rocker

Further strength with a forged rocker and seat stays keep the back of the bike in line through sketchy landings.

Dual crown builds run a Marzocchi Bomber 58 with huge 40mm stanchions and SRAM GX DH drivetrain components. Single crown Bottlerockets use a Marzocchi Bomber Z for with 38mm stanchions and a dropper post. Both builds have Maven brakes and all models run a Marzocchi Bomber Air shock.
