Marin Alpine Trail chainstay flip chip detail.

Adjustable Geometry

With the integrated flip chips, adjustable headset and an aftermarket 29” rear wheel, Alpine Trail aluminum riders can select 12 unique configurations to run their bikes. These configurations allow the best fine-tuning of chassis to trail conditions available. Flip chips are easy to reconfigure trailside and easily done using a 6mm hex wrench, require no additional parts, and incorporate laser-etched graphics that indicate the position of the chips. The stock 27.5” rear wheel can be swapped out for a 29” rear wheel (not included) if desired, along with changing the position of the seatstay flip chips. Furthermore, the flip chips located at the seatstay pivots alter the bottom bracket height and chainstay length (low BB/long CS setting = 345/442mm, high BB/short CS setting = 352/435mm) so that riders can perfectly dial their bike in to match the terrain they are looking to conquer.
