The Specialized HDS Sub transition spacer bridges the gap between a Roval Rapide cockpit and the Tarmac SL7 headset, giving riders a clean path to upgrade their stem and bar setup without replacing the complete steerer assembly. It sits above the headset bearing to maintain proper spacing and a tidy finish at the top of the fork.
Built from lightweight material for durability on the road, this single-piece spacer is sized to match Tarmac SL7 headset dimensions precisely, so fit and function remain consistent after installation. It ships as one piece, making it a straightforward addition when swapping to a Roval Rapide cockpit on a compatible Tarmac SL7 frame.
