Stumpjumper FSR Comp 650b

Icon

2017 Stumpjumper FSR Comp 650b

When you need to blend ruggedness, efficiency, and down right nimbleness into one trail bike, it's pretty damn hard to beat the confidence inspiring construction of an alloy frame like the Stumpjumper FSR Comp 650b. 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. 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.

best bike I've ever had

I've had this bike for a while and I've loved it ever since I swapped the bars for some carbon bars and now its even better. The only flaw is that the dropper post clicks up and down but I don't really mind. :)
