The new Stumpjumper is the ultimate singletrack flow finder. It climbs and accelerates like it has a motor, descends with authority, and flat out tears through every conceivable trail condition. There's never been an all-round trail bike this light, this efficient, this capable.
"Since There’ve Been Mountain Bikes, There’ve Been Stumpjumpers"
The Geometry of Control
The generous cockpit centers you on the bike, improving traction and corner control. The low bottom bracket, slack headtube angle and reduced fork offset keep things stable in the rough. A steep seat tube optimizes power output and climbing balance. Short chainstays keep things nimble.
To hone handling to your style and terrain, simply switch the FlipChip at the rear shock eye to change bottom bracket height by 7mm and headtube angle by one-half degree. Low and lax delivers more stability, while high and steep makes for a more nimble ride.
Nothing Is Lighter and Stiffer
The frame is the backbone of the bike. It's the origin of control and efficiency, and it's the centerpiece of any serious weight saving effort. The full Stumpjumper frame assembly* (barely) tips the scales at an unbelievable 5.3 Ibs (2,420g), but we didn't compromise in our quest for light weight. The Stumpy punches above its weight, settling the bar for mid-travel trail bikes in handling characteristics, pedaling efficiency and trail toughness.
