Going down?

World Cup champion Session is proven to be the fastest downhill mountain bike. And with its amazing suspension, it’s the overall best downhiller that the scene has ever seen.

You need a bike that will not only withstand the brutal demands of downhill, but excel at them. You need a proven winner on the World Cup circuit. You need Session.

OCLV mountain carbon with InTension

Trek's InTension material is built into complex moulding areas to make OCLV Mountain Carbon even stronger and lighter than before. This advanced low-density, ultra-stiff material has 4 times the flexural strenth of a carbon-only structure, and it 8 times stiffer.


MicroTruss housing guides are built directly into the frame for the lightest, cleanest external cable routing.

Carbon Armour

Sometimes you need a little extra protection, so Trek developed a light, tough external Carbon Armour polymer shield. It provides reassurance when you know your down tube is bound to take some abuse.

Mino Link

Fine tune head tube angle by 1/2 degree 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.

Active Breaking Pivot

Trek's patented Active Breaking Pivot allows your suspension to work freely whether you're on the brakes or off. It's smooth, controlled suspension that's at its best all the time.
