The history of TUNE began in 1988. Uli Fahl, born in the Black Forest in southwestern Germany near the French border, was working as a chemist for a lubricant manufacturer while spending his weekends climbing the Alps, when he suddenly began to wonder, "How can I make my bike even lighter to enjoy riding it more?"
Starting with their quick-release skewers, considered the oldest product in TUNE's history, they offer a wide range of components including stems, seatposts, and seat clamps that combine exceptional lightness with durability, as well as hubs equipped with conversion kits and small parts.
Each product is machined from a solid block of aluminum with precision, featuring a superb surface finish and seven distinct vibrant colors—a lineup that continues to be created through an unceasing passion and spirit of inquiry.
The heart of tune / What is TUNE
In-house production
In-house production is at the core of TUNE. At our own factory, we use the highest quality alloys to craft precision parts with lathes and milling machines.
Friedhelm and Dennis are responsible for every stage of production. From raw materials to finished machined parts, they carry out their work with reliable skill and experience. 3D-CAD models of the products are converted into executable code for CNC machines using modern software. Ultimately, Friedhelm uses the optimal tools and correct production methods to manufacture the world's highest quality bicycle parts.
Machining
Once a program is created, a machine equipped with the appropriate tools begins production. With automation solutions, CNC machines can operate autonomously for several hours.
Using various tools, the desired part is gradually formed from the raw material. After machining, only about 10–15% of the raw material remains as the finished part. The resulting scrap is collected and recycled according to its type.
When switching to different parts, the machine must be equipped with different tools and its dimensions must be measured. This setup process requires time and precision, but it ensures repeatability when producing different parts.
Quality Control / Production Quality Control
During production, part dimensional tolerances are constantly monitored to ensure perfect quality.
For the strictest tolerances, such as bearing housings in hubs, where even an open factory door during winter can cause dimensional changes, each hub body is inspected piece-by-piece in subsequent processes to ensure it meets the required tolerances.
A complete test report is prepared for every single part. Inspection procedures and tolerances are detailed in the report, serving as a guide to streamline the quality control process.
