Titanium Cover for Cervélo S5 HB19 Carbon Handlebar – Rubber Cover Replacement
Upgrade your Cervélo S5 HB19 carbon cockpit with a precision-made titanium replacement cover.
This aftermarket cover is designed for the HB19 Carbon Handlebar used on the latest-generation Cervélo S5. It replaces the original rubber cover with a more secure and durable metal component.
Unlike the flexible factory rubber cover, the titanium version is less likely to loosen or fall off during normal riding, transportation or cleaning. Its clean shape follows the design of the HB19 cockpit, adding a refined metallic detail without disrupting the aerodynamic appearance of the bicycle.
The cover uses a two-hole mounting design and is supplied with one matching spacer. Natural silver titanium is the standard finish. Anodized color finishes may also be available for riders who want to coordinate the cover with their frame, bolts or other titanium components.
