Micro Boost rear hub
Micro – Lightweight MTB Hubs Built for Real Trail Use
Enduro trails, downhill lines, fast after-work laps or full-power e-MTB rides? Micro is built for exactly that.
Micro brings Tune lightweight performance to the MTB world in a robust and versatile package. Handmade in Buggingen, Germany, this hub set combines low weight, high durability and the reliability needed for modern mountain bikes — including e-MTBs.
Instead of chasing weight savings at any cost, we focused on the right balance: as light as technically possible, but strong enough for demanding trail use. The result is a hub set that feels fast, direct and efficient, while still being ready for hard riding.
At only 368g per hub set, Micro is impressively light for its category. At the same time, it is robust enough to be approved for full-power e-MTB use. The newly developed freewheel system delivers 138 engagement points, giving you quick power transfer when accelerating out of corners, climbing technical sections or putting down power on steep terrain.
Additional highlights include:
- Lightweight MTB hub set handmade in Germany.
- Approved for full-power e-MTB use.
- J-Bend flanges for a strong, proven and service-friendly wheel build.
- Conical hubshell design for a modern, dynamic look.
- New axle design: no shims required.
- Improved sealing for better weather resistance.
- Newly designed freewheel system with 138 engagement points.
- Heat-treated steel pawls for improved freewheel durability.
- Optional bearings: Enduro Bearings ABEC-5 steel bearings or Enduro Bearings XD-15 ceramic bearings with lifetime warranty.
Whether you are pushing hard on technical trails, building a lightweight e-MTB wheelset or simply looking for a reliable Made-in-Germany MTB hub, Micro is ready. Strong, light and easy to service — a hub set made for riders who expect more from every ride.
