Bianchi Magma 9.S Deore Mountain Bike 2021
The Bianchi Magma 9.S Deore Mountain Bike aims to open the door to riders looking for their first performance bike. The lightweight aluminium frame uses cross-country optimised geometry to improve efficiency on the trail, and features internally routed cables for a premium look worthy of its iconic Bianchi heritage. Equipped with the latest 12-speed Shimano drivetrain the Magma 9.S stays calm and collected on the steepest climbs, with the wide-range 10-51t cassette ensuring a perfect ratio in all scenarios. The single front chainring reduces weight and simplifies the drivetrain to reduce maintenance, with the chain being kept securely on the ring through use of a clutch derailleur and narrow-wide ring profile.
The RockShox Judy Silver TK Solo Air fork can be adjusted to the weight of the rider, allowing the 100mm of smooth suspension travel to be tuned to your preference. Inherently lighter than a coil fork, air suspension further reduces the weight of the bike for a spritely ride-character. As the wheel size of choice for XC World Cup riders, 29" wheels roll well over technical terrain and carry speed through ruts, with their larger diameter providing a more stable ride.
