Not all trail bikes are made the same. When it comes to getting gnarly on the singletrack, some bikes will come out on top over others. The Specialized Stumpjumper EVO Alloy XT Jenson Exclusive Bike is ready to rock and roll on any trail around. It has an M5 alloy chassis and rear end. The frame uses 170mm of travel on the front and 150mm of travel on the rear. The frame also features a threaded bottom bracket shell, SWAT Door integration for extra storage, fully enclosed internal cable routing, Boost spacing, and a host pivot BB adjustment. This frame comes with a Fox Float X Performance rear shock.
This Jenson Exclusive version of the Specialized Stumpjumper Bike comes with a Shimano XT Trail 12-speed drivetrain. This includes a cassette that has a hill-crushing 10-51T gear range that makes climbing and pedaling through rough terrain a breeze. Shimano XT hydraulic disc brakes provide excellent stopping power so you can descend with confidence. Crankbrothers Synthesis Enduro Alloy Rims are paired with Maxxis tires that can be set up tubeless for a smoother ride, better traction, and fewer flats. With the OneUp V2 Dropper Post, you'll be able to quickly lift and lower your saddle with the press of a lever.

With so many choices of bikes you can choose to purchase, not all of them are made to fit every rider out there. Some bikes may be too progressive, some too long, some too short, etc. When a bike comes from the factory, it may not be totally suitable for the rider which leads to more money coming out of pocket to help tailor a more fitting ride. Luckily, there are brands out there who know this is a problem so they make adjustments from the factory to help better fit their customer base. One of these brands is Juliana Bicycles.
