absoluteBLACK Top Cap with Integrated Bolt - Red
It's probably the best top cap you will ever have. One piece, bolt and topcap with Allen (hex) 5mm socket.
Will fit to every standard starnut. Not suitable for "expanding" star nuts with the steel coil spring (used in carbon steerer). But it is compatible with ENVE Compression Plug (recommended for carbon steerers).
Material: CNC Machined 7075 Aluminium
Key: 5mm Allen
Mfr Claimed Weight
Note: If your top cap sits from an angle on the stem (does not touch stem with whole circumference), it means your starnut sits from an angle. You will have to make it straight prior to mounting Ab top cap. To do that you can use old steel bolt and a hammer.
