SUMMARY

This gem is sporting a 150 mm (sizes M-XL) X-Fusion dropper, and Fox handles the suspension duties with a 34 Rhythm upfront and DPS Performance to the rear. Shimano keeps the wheels spinning with the company’s SLX 111 groupset while stopping power is delivered to the 200/180 mm rotors by way of Shimano’s Deore brakes. Specialized designed the asymmetric frame around the company’s patented FSR suspension system. A single-sided arm between the top tube and seat tube runs parallel with the shock adding stiffness to the front of the bike while reducing unnecessary weight. This design first seen on the company’s downhill bike, and aside from function, it creates a nice looking bike with smooth lines. 

Other notable features include a standard BSA threaded bottom bracket, nonproprietary metric sized shock, and a Flip Chip that adjusts the bottom bracket height by 6 mm and slackens the head tube by half-a-degree if that’s what you’re looking for. 

THE RIDE

The first step in testing the Stumpjumper ST was Alafia State Park in Florida, which is full of short, punchy climbs, drops, berms, and gap jumps. The Stumpy ST felt comfortable right away, and I quickly found myself at ease going into sections blind, given a local’s wheel was not far out of reach. Riding with the locals, with far more skill than my own and also riding a Stumpy ST, I saw them backflip doubles, boost a 30-foot swamp gap and even spin a 360 like it was a 26-inch dirt-jumper. Weighing in over the 30-pound mark, the Alloy Comp model carries its weight well. 

At speed, the bike feels agile and willing to take on more than one would expect for a «Short Travel» trail bike. 

CONCLUSION

Specialized did an excellent job in the latest iteration of the Stumpjumper.
