Features
Alpha Platinum Aluminium
Our premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Integrated frame protection
Integrated guards protect top tube from dual-crown fork stanchion impact, and down tube from trail debris. The down tube guard is removable, allowing riders to shed valuable grams on race day, or to replace the guard as necessary.
Mino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
