Alpha Platinum AluminiumOur premium lightweight aluminium is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
Mino Link adjustable geometryFine 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.
Boost148/110Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
