The Eternal Stem impresses with its uniquely filigree, wide and aggressive appearance, as well as with technical refinements.

The design was adapted to the high demands of modern cycling through simulations and countless tests. In extreme situations you need complete confidence, which the Eternal Stem gives you!

Thanks to the precisely transmitted steering movements, you can always keep even the most difficult line safely. With a clamp width of 55 mm, the Eternal ensures optimal stiffness in the cockpit, but is still compatible with virtually all handlebars, regardless of the rise. Made from high-strength aerospace aluminum, it is built to last.

Hochwertiger und individueller Vorbau

Habe den 42mm Vorbau in Schwarz und kann nur sagen: Perfekt! Die Qualität ist super und für alle, die auf die Optik von Frästeilen stehen ist das DER Vorbau. Ein kleines Kunstwerk am Bike, aber dabei trotzdem unaufdringlich.
Außerdem ein extrem freundlicher und vor allem lösungsorientierter Kundensupport bei OAK! Meine Anliegen wurde schnell und zufriedenstellend gelöst.
Danke an das Team von OAK! Kann den Vorbau und den Kundensupport nur weiterempfehlen!

Knarzt und knarzt

Leider knarzt der Vorbau bei mir sowohl mit einem Sixpack Millenium Alu Lenker als auch mit einem Title Reform Alu Lenker. Ich habe die Schrauben sauber gefettet, verschiedene Montagepasten versucht usw. Hat alles nichts gebracht.

Das geilste Teil an meinem Fahrrad

Schwer die richtigen Worte zu finden, aber MEISTERWERK sollte es aber treffend beschreiben. Mein einziger Wunsch wäre, das noch farblich passende Schrauben dabei sind (habe den goldenen), die silbernen können dem Vorbau nicht gerecht werden. Mehr Auswahl bei den schrauben würde dieses Kauferlebnis einfach abrunden. #bestevorbauammarkt

Very good job 👏

After buying the brake levers for my TRP, I added a stem.
The products are super well finished, of very good quality and very aesthetic.
Well done OAK components for your work.
