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.
Super light, but one time use?

I installed it with grease around the rim because it has to slide around to get tight. I used a torque wrench to something like 3 Nm, maybe it was less. Which should be fine for a m5, and enough to preload the headset. The first time I removed it I couldn't undo it easily. I used a long handled allen key, it put a crack in it from all the force it took to remove. I'll admit my star fangled nut may have not been perfectly straight, which could be the whole caveat to this being a great part (so I hope you read this far). So either the crack made the screw bent or it bent because of my star fangled nut. I am going to have to stick to two piece from now on, other than my problems, 3g is amazing and cant be beat.

A very light and nice looking top cap. Keep in mind it is one piece so there is more friction when tightening your headset due to the entire cap turning.
