Spina Scapulae is Latin for shoulder blade, or simply, scapula. THM's Spina covers the "shoulders" of their Scapula-series fork crowns to create a seamless look for modern frames with integrated headsets and enlarged lower head tubes. Please note that the Spina is not compatible with the Scapula F aerodynamic fork.
The Spina is installed under and held in place by your headset's lower crown race. Installation of this fork cover requires no special tools other than those required to access and install the crown race.
