The Transition Spur is designed as a high-performance mountain bike that occupies the space between traditional cross-country efficiency and trail-oriented capability. It utilises a lightweight carbon fibre frameset paired with a flex-stay suspension design to provide a platform that is both responsive under power and composed on technical terrain. To cater to a variety of rider preferences and performance requirements, the Spur is offered in several distinct component configurations. Each specification is carefully curated to provide a specific ride quality, balancing weight, drivetrain technology, and suspension performance to suit different trail conditions and user needs.
