It is ideal for you if...
You are looking for a trail bike made of carbon that keeps weight to a minimum, without giving up capacity. You like to do it all: long alpine climbs, rootsy Aspen slalom, and fast XC singletrack, and you're looking for a bike that can keep up the pace on the climbs and perform on the descents. Maintaining a light weight with a carbon frame is important to you, and you want to enjoy the light and precise shifting of a Shimano XTR drivetrain.
Features
The Top Fuel Gen 4 convinces with an incredibly light build, improved frame storage and more adjustability for all types of rides and riders.
With 120 mm of travel at the rear and 130 mm at the front of the RockShox suspension, it provides a balanced pedal stroke that remains efficient on climbs and playful on descents.
The 4-position Mino Link allows you to easily adjust the geometry or progression of the suspension depending on where and how you want to ride.
In-frame storage, with an improved BITS bag system, allows for convenient storage of tools, cameras and food.
It's more ready than ever for any upgrade, with room for larger 140mm forks and longer-stroke shocks, offering up to 130mm of rear travel, plus room for extra-long dropper posts. .
