FROM THE BLACK FOREST.
TUNE / BLACK FOREST, GERMANY
Lightness, with precision.
Add a touch of color to your car.
The joy of riding,
in every small part.
The contours of machined aluminum. Vibrant anodized finishes. An astonishing lightness when held in your hand. Hailing from Germany's Black Forest, TUNE is a parts brand that makes even the time spent building your bike enjoyable.
It all began in 1988. Driven by a desire to ride to the mountains on a lighter bike, Uli Pfahl's ingenuity gave rise to a unique approach to manufacturing. From the foundation of your bike to the components around the handlebars. Make your next upgrade with TUNE.
THE HEART OF TUNE
Lightness backed by
precision.
The words "lightweight" and "high precision" come to life in the factory. TUNE values both the process of creating a form and the process of verifying it.
01 / IN-HOUSE MACHINING
Machining the necessary form
from a solid block of aluminum.
Alloy materials are precisely machined on lathes and milling machines in our own factory. 3D designs are converted into CNC machine movements, and by selecting the right tools and machining methods, each part is crafted to perfection.
Deciding what to keep and what to machine away. This meticulous process creates the lightness and contours that define TUNE.
02 / CHECKED ONE BY ONE
Checking every detail,
down to where the bearings fit.
The areas inside the hub that hold the bearings require strict dimensional control. In addition to checks during machining, TUNE inspects each hub body individually after machining to ensure it falls within the specified dimensional tolerances.
We pay close attention not only to the visible finish but also to the parts that are hidden once assembled. That is our commitment to precision.
03 / TESTING & DEVELOPMENT
Verified through testing
before you ride.
TUNE development includes fatigue life testing, where prototype wheels are subjected to repeated loads, as well as impact testing and torque fatigue testing related to drive and braking. The results are applied to the next design.
Advancing weight reduction through the cycle of design and verification. The craftsmanship that goes beyond the numbers is another reason to choose TUNE.
