The Absolute Black top cap is an extremely light and very elegant piece of bicycle componentry. CNC Machined from 7075 Aluminium the bolt and top cap in one design creates a simple visually pleasing interface. When looking at your bike it would take a true aficionado to notice a truly unique top cap, this is the top cap for them. The concave shape is a truly unique look for the top of any stem and will save you around 10g compared to a more traditional steel bolt top cap.
The Absolute Black top cap is only compatible with compression plugs that feature a separate top cap bolt and adjustment bolt. The only compression plug that do not feature this setup are ones with a large metal spring and one long steel M6 bolt. If you have any standard compression plug such as an ENVE you’ll be happy with the Absolute Black top cap.
