About Rule Components
Rule is a performance-focused cycling brand producing premium parts with an emphasis on lightweight construction, modern materials and clean design.
At Port Velo, we are introducing Rule through its 3D Carbon Saddle range, with guidance on fit, suitability and setup rather than a one-click add-to-cart approach.
Why contact us first?
A premium saddle is not something we want to sell blind. Shape, width, rail compatibility, bike position and intended use all need checking before making the right choice.
If you are interested in Rule, get in touch and we can talk through fit, bike setup and whether the 135 mm or 145 mm option is more likely to suit you.
