Stumpjumper Comp Alloy 29/6Fattie
2018 Stumpjumper Comp Alloy 29/6Fattie
Don't get us wrong—carbon is awesome. But when it comes to maintaining peace of mind while you're getting rowdy, nothing compares to the confidence of our alloy Stumpjumper Comp 29/6Fattie. It's light, rugged, and packed with all the spec and travel you need to run it wide open out on the trail.
It features an M5 alloy construction that's lightweight, durable, and plenty stiff and compliant, while SRAM's most durable one-by components have been hand-selected to ensure that you get the most performance over rugged terrain possible. To make things even better, the Stumpy's design also allows you the opportunity to toggle between 29-inch wheels and 6Fattie wheels (not included), allowing the ultimate in configuration options for the trail at hand.
And when you factor in our proprietary Rx Trail Tune at the shock, plus an aggressive, trail-eating geometry that features absurdly short chainstays, a roomy top tube, a low bottom bracket, and a slacked out front end, you get a trail bike that you can be confident in, season after season.
