To squeeze every last ounce of fun out of the trail you need a bike that can take a hit and dish it right back out ten-fold. In other words you need the Stumpjumper FSR Comp 6Fattie. It features a M5 alloy construction thats lightweight and durable but what were most excited to debut is our all-new 6Fattie Wheel System.
It takes 650b wheels and wraps them in 3.0" tyres in order to achieve levels of traction control and floatation that will shake your idea of trail riding to the core. And when you combine a mix of SRAM and Shimanos most durable components with a our 6Fattie Trail Geometry that maintains a roomy top tube ultra-short chainstays and a slacked out front end youre looking at the future of trail bikes.
M5 alloy Trail Chassis with Stumpjumper FSR 6Fattie M5 alloy rear end with 148mm spacing proved to be the right material for the job allowing a lightweight durable frame with a low and slack geometry thats equal parts snappy and efficient on climbs and descents. It also allowed us to incorporate our revolutionary 6Fattie wheels and tyres without compromising on our hallmark short chainstays that provide unrivalled handling and climbing prowess.
Connected with our FSR 6-Pack Linkage a custom FOX FLOAT Performance DPS rear shock features 135mm of plush adjustable suspension while our Rx Trail Tune provides a more supple responsive and efficient feel for climbing up and descending down the trail.
FOX 34 Plus Performance fork provides 150mm of trail-eating travel. It accepts 15mm thru-axles for added responsiveness and strength while its three-position compression adjust puts out the perfect ride quality for every stage of the trail.
650bx3.0" 6Fattie Purgatory tyre features a perfectly sized contact patch for life-changing levels of traction and floatation all without sacrificing climbing efficiency or descending prowess.
650bx3.0" 6Fattie Ground Control tyre features the perfect contact patch size to traction and floatation in the corners and while climbing.
Command Post IRcc seatpost features 12 positions of up to 125mm of height adjustability for a more customizable position ultimately resulting in more control and increased handling on both climbs and descents.
