With traditional frame designs, engineers adjust front-centre lengths for each frame size but use a single, fixed rear-centre length. This approach leaves riders of certain body types in a poor position when standing. Poor body position leads to uneven weight distribution and negatively affects traction, control and overall performance and ride characteristics. A simple solution to a complex problem, Gravity Tune fixes the front-centre/rear-centre ratio across all frame sizes, effectively optimizing geometry for every bike in the line. As a result, weight is always optimally distributed – regardless of rider height. Available only on Norco Bikes, Gravity Tune means equal ride characteristics and unrivalled control for all.
