The Zesty AM 427 has been completely overhauled, now accommodating the standard Boost, a metric shock absorber and wheels 27.5 inches and larger. Its patented OST+ suspension, based on virtual pivot point kinematics, provides an incomparable quality of steering without generating any pumping. Its lockable SUNTOUR Aion 35-mm fork mount offers both comfort and safety.
Its 30-tooth single chainring, along with a SHIMANO 11-42 cassette and 1×10 transmission, artfully blend smoothness and efficiency. Installed with MICHELIN WILD ROCK’R2 LIGHT EDITION GUMX 27.5 x 2.35 tires, the Boost format wheels contribute the requisite stiffness and stability, even on the most demanding courses.
