Specialized S-Works Stumpjumper 29" Mountain Bike 2020
The Specialized S-Works Stumpjumper 29" Mountain Bike is the trail riders dream, combining a super-premium carbon fibre construction and some of the very best componentry available to deliver a fast and thrilling ride.
FACT 11r carbon fibre is the lightest frameset material that Specialized produce, leading to a seriously lightweight bike that handles nimbly, climbs with ease and has a willingness to tackle jumps. When it comes to landing, the FOX FLOAT Factory suspension system combines 150mm of plush travel at the front and a highly adjustable rear shock to get the ride quality you need.
The Shimano XTR M9100 gearset features 12-speed shifting to quickly pop you into the right cog for getting up and over the next obstacle. Rolling on a set of Roval Traverse SL tubeless-ready wheels, this is a head-to-toe premium trail bike that will bring endless smiles to your face, wherever you ride it.
