This spacer kit is specific to the Cervelo Caledonia 5 frameset / bike design and used with the ST31 Carbon and ST32 Alloy stems. It features two height options of top bearing covers with integrate perfectly with the frame, and several split-type spacers in the shape of the Caledonia 5 and ST31/32 stem design. The spacers and covers are designed with a channel to integrate perfectly with the internal routing system.

The split spacer system allows the stem height to be adjusted easily for fit purposes without wire/housing disassembly. Cervelo proved the effectiveness of the system S-series models before bringing it to the more versatile Caledonia 5 design. Please keep in mind that the standard Caledonia features a round steerer tube and thus uses normal round spacers.
