Tune Micro CL Rear Hub:

At first glance, one might think that the Micro hub is a revised version of the KillHill model. In fact, however, it is a completely new design, conceived from scratch and featuring numerous useful improvements.

The new Tune hubs no longer require washers for axial play adjustment, making them much more user-friendly and easier to maintain. Furthermore, Enduro Bearings has been chosen as the main supplier for hub bearings, and all hubs are fitted with new seals, ensuring they are not only lightweight but also incredibly durable.
The Micro consists of a one-piece, CNC-machined aluminium body and two deep-groove ball bearings. The Micro hub is the perfect introduction to the world of lightweight hubs from Tune. Don’t be fooled by its status as an entry-level model: the Micro hub is a true performance marvel. Weighing just 349g (+/- 3%, for the set), it is not only extremely light but, thanks to its classic J-bend flanges, also extremely stable and therefore versatile, even off-road.

Whether on a road bike or a gravel bike, the Micro Hub is the perfect companion for all your adventures, after-work rides or town sign sprints. Naturally, this hub set is also handmade in Germany.

Tune hub bearings:

Two types of ball bearings are available, both from Enduro Bearings: as standard, the Enduro Bearings ABEC5. These high-quality ball bearings offer reliable performance for a wide range of applications. They are characterised by their precision and durability and are an excellent choice for riders who value quality. The Ceramic XD-15 ball bearings. These ceramic hybrid ball bearings are renowned for their exceptional smoothness and durability. Enduro Bearings XD15 ceramic hybrid bearings come with a lifetime guarantee, making them the ultimate choice for riders who refuse to compromise on performance and reliability. Ideal for use in the most demanding conditions.

Enduro Bearings ABEC 5 ball bearings:

Enduro’s ABEC-5 ball bearings feature mirror-smooth polished raceways made from a high-carbon chrome alloy (52100), paired with grade 10 balls. Enduro designs all radial bearings with deeper grooves to accommodate the largest possible balls, enabling maximum contact area and a significantly longer bearing life. The LLU/LLB seal combination on these bearings, developed specifically for bicycle applications, uses a protective grey LLU seal facing outwards towards the elements to reduce contamination from water or dirt, whilst the lighter (lower sealing resistance) black LLB seals, which face inwards, keep the 90% filled Mobil XHP 222 high-pressure grease where it belongs.
