{"product_id":"trek-session-al-frameset-37959","title":"Trek Session AL Frameset","description":"\u003cp\u003eSession AL Frameset gives you the perfect foundation for building your ideal downhill machine. Its high-pivot suspension design keeps you nimble, planted, and fast through the roughest lines, while the burly Alpha Platinum Aluminum frame is built to handle repeated hits on steep, technical terrain.\u003c\/p\u003e\u003ch2\u003eHighlights\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll speed, no hang-ups\u003c\/strong\u003e - Session’s high-pivot design results in a rearward axle path that lets the back wheel move with the rearward force from bumps, not against it.

By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eKey
