The OAK Components Eternal Topcap in Raw finish transcends the simple function of a stem cap to become a true CNC machining jewel on your cockpit. Its unique engravings with fairytale design combined with 100% machined aerospace aluminum make it a premium accessory that immediately captures the eye. Weighing only 6.4 g (14 g with bolt), this ultra-lightweight cap combines high-end aesthetics and proven functionality for the most demanding disciplines: DH, Enduro and E-Bike.

Delivered complete with its silver bolt and an OAK sticker pack, it installs in seconds.

OAK Components Philosophy

OAK Components is a German brand founded by MTB-passionate engineers who ride daily with their creations. Based in Ebermannsdorf, Germany, the company develops CNC-machined premium components by combining advanced digital simulations, laboratory testing (ASTM standards) and intensive field validation on the most brutal trails. Every OAK part integrates user feedback from around the world to offer the best balance between aesthetics, lightness, stiffness and durability. The Eternal range (stems, caps, titanium bolts) embodies this philosophy: a bold and filigree design, top-quality aeronautical materials, and ASTM Category 5 certification validating their use in DH, Enduro and E-Bike up to 130 kg load.

Use and Maintenance

Installing the Eternal Topcap is simple and quick: place the cap on the upper headset spacer, insert the supplied bolt and tighten moderately (2-3 Nm torque recommended) to preload the headset before finally tightening the stem. The Raw aluminum finish requires no special maintenance – simple cleaning with soapy water is sufficient after rides. If you wish to preserve the original bare appearance, avoid abrasive products; if you prefer to let the metal develop a natural patina, simply let time and the elements do their work for an even more authentic and personal look.

Customization and Compatibility

The Eternal Raw cap harmonizes perfectly with the OAK Eternal stem (available in 35, 42 and 50 mm, black, raw, lunar gray finishes…) to create an ultra-coherent tone-on-tone cockpit. You can also combine it with OAK titanium bolt kits available in 10+ colors (gold, copper, purple, green, red…) for a personalized color touch. Compatible with all 1″1/8 headset standards, it mounts equally well on Renthal, Race Face, Chromag, Hope or Burgtec stems. OAK also offers the Eternal Topcap in other finishes: black, gold, kashgold, green, red, purple – collect them to change your bike's style according to your mood!
