Polygon Syncline Assembly Guide
Your bike needs minor assembly before riding; use the tools and videos included.
As a guide, it'll take 10-40min depending on whether you're an experienced bike assembler or have little to no mechanical experience.
Side Note: Your cables will stretch during the initial bed-in period and must be adjusted by an experienced mechanic around 150km of riding.
