The TUNE guide

Dragonspine Cycling, Chicago

What goes into a TUNE hub and wheel, how they are made by hand in the Black Forest, how to trade up from a current bike or wheelset, and the warranty and crash replacement behind every TUNE wheel.

01 / Technology

The hub comes first

TUNE began as a hub maker, and the hub is still the heart of every TUNE wheel. The Nano hub shells are machined from aerospace-grade aluminium in Buggingen, every hub part except the bearings comes from Germany, and a new axle design sets bearing play without shims. TUNE's own POEtry freewheel engages at 69 points on the road and gravel hubs and at 138 on the MTB hubs, and standard-sized bearings keep service quick.

69: Points of engagement on the POEtry 69 freewheel, 138 on the MTB hubs
24 mm: Internal width of the hooked Nano Road and Nano CS rims, for 28 to 45 mm tires
130 kg: System weight limit (287 lb) on Nano Road, Nano CS and Nano Gravel wheels
1989: TUNE founded by Uli Fahl in the Black Forest

Nano CS: a hub made for carbon spokes

Carbon spokes can hardly bend, so the spoke hole in the hub has to line up exactly with the rim. TUNE's patented Nano CS hub shell uses a ball-milled spoke hole that lets each carbon spoke align itself and run straight from hub to rim, without unwanted stress. Nano CS wheels come with spare carbon spokes for every spoke length in the set, and the hub internals are shared with the Nano and Micro hubs for easy service.

What makes the difference

HookedHooked rim design

The Nano Road and Nano CS carbon rims are hooked, for wide tire compatibility and secure tire retention.

POEtryTUNE freewheel system

TUNE's own freewheel: 69 points of engagement on the road and gravel hubs, 138 on the MTB hubs and 40 on Yokto.

CSCarbon spoke interface

A patented spoke hole geometry that lets every carbon spoke run straight, for performance and durability.

XD-15Enduro ceramic bearings

Every wheel and hubset comes with Enduro ABEC-5 steel or Enduro XD-15 ceramic bearings, the ceramic with a limited lifetime warranty.

AeroOptimized rim profiles

A symmetric front rim and an asymmetric rear rim for better aerodynamics and balanced spoke tension, tested in the wind tunnel and on the velodrome.

Made in GermanySince 1989

Hubs precision-machined and every wheel hand-built at TUNE's factory in Buggingen, in the Black Forest.

Yokto: functional lightweight

Yokto is TUNE's top line and its engineering philosophy: as light as possible, but never at the expense of durability or safety. The Yokto hubset weighs 225 g for the pair, a little more than the absolute lightest by design, with Enduro XD-15 ceramic bearings and an axle that sets bearing play without shims. On it, the Yokto 3030 wheelset weighs 1,030 g, and TUNE calls it one of the lightest, if not the lightest, UCI-approved wheelsets in the world (as of February 2025).

Yokto 3030: 1,030 g a set, UCI approved

Tested to failure

Every TUNE product is developed and tested in Buggingen, with physical tests rather than computer simulations alone. Each built wheel is measured for lateral stiffness. Prototype wheels run about 8,000 km on a drum under exaggerated load, and an impact test drops a 40 kg weight from rising heights until the wheel breaks, so the stated weight limits carry a real safety factor. The Nano rims were also developed in the wind tunnel and on the velodrome.

02 / Made in Germany

Built by hand in the Black Forest

In 1989 Uli Fahl quit his job as a chemist, moved back to the Black Forest and started TUNE. Its parts are still made in Buggingen: hub parts are turned and milled in-house from the best alloys, and every hub body is checked against its tolerances with its own test report.

Machined in-house. CNC machines shape each hub part from raw material. Only 10 to 15% of the material ends up in the finished part, and the chips are recycled.
Laced and tensioned. The spokes are threaded into the hub, then the hub is joined to the rim and the wheel is pre-tensioned.
Trued by hand. The final centering is always done by hand, keeping lateral and radial runout to a minimum and relieving spoke stress so the wheel holds its tension.
Checked and shipped. Every wheel passes a test protocol before the decals go on, then ships in a box made for wheels.

About TUNE

TUNE's story begins in 1988 with Uli Fahl, a chemist from the Black Forest working in Munich, and a 20 kg mountain bike that was far too heavy for the climbs he rode in the Alps. He swapped its screws for aluminium ones, built weight-optimized rear derailleur kits and the super-light AC8 quick release, and riders chasing a hardtail under 13 kg began ordering from him. In 1989 he quit his job, founded TUNE and moved back to the Black Forest, where the company still makes its parts today, in Buggingen.

Hubs and wheels soon became the center of the work. Uli's credo is that the wheels are the best way to save weight, because every gram saved in a rotating mass is felt on the bike. In the nineties TUNE launched a ceramic bottom bracket that came out of a Tour de France development, a rear hub under 100 g called the decibel for its loud freewheel, and an extra-long quick release for the Munich Space Chair, which the Technical University of Munich built for the MIR space station.

Today TUNE machines its hub parts in-house and builds every wheel by hand in Buggingen. The Nano Road and Nano CS Road wheels use TUNE's own hooked carbon rims, developed in the wind tunnel and on the velodrome, in 35, 45 and 60 mm, with steel spokes on the Nano hub or carbon spokes on the patented Nano CS hub. The Yokto wheelsets are built on the 225 g Yokto hubset, and the Yokto 3030 weighs 1,030 g a set. Nano Gravel 45 and Nano XC take the same hubs off-road, and the hubs come as hubsets too: Yokto, Nano CS, Nano and Micro for road and gravel, Nano Boost and Micro Boost for mountain bikes.

In July 2023, Carbovation GmbH, the Friedrichshafen company behind Lightweight, acquired TUNE. The two brands are managed independently and keep their own identities.

Dragonspine Cycling carries TUNE's US wheel range: Nano Road, Nano CS Road, Nano Gravel 45, Nano XC and both Yokto wheelsets, with Standard or ceramic bearings and the freehub body for each common drivetrain, plus TUNE hubsets for road, gravel and MTB. Orders ship within the continental US, and the Chicago location at 4357 N Milwaukee Ave is the place to talk through freehub standards, tire sizes and setup, or call +1 (872) 946-7006.

FAQ

Which TUNE wheel suits which riding?

Nano Road is the steel-spoke road wheel in 35, 45 and 60 mm, and Nano CS Road is the same range with carbon spokes and less weight. Yokto 3030 is the 1,030 g climbing wheelset and Yokto 4550 the all-round aero Yokto. Nano Gravel 45 is the gravel wheel for 38 to 66 mm tires, and Nano XC is the 29 inch cross-country wheel.

Standard or ceramic bearings?

Nano wheelsets and hubsets come with Enduro ABEC-5 steel bearings as Standard, or Enduro XD-15 ceramic bearings, which carry a limited lifetime warranty. Yokto wheels and hubs always come with XD-15 ceramic bearings.

Which freehub bodies are available?

Nano Road, Nano CS Road and Yokto come with Shimano HG, SRAM XD/XDR or Campagnolo N3W. Nano Gravel 45 adds Shimano MicroSpline, and Nano XC comes with Shimano MicroSpline or SRAM XD/XDR. Pick the body that matches the cassette.

Is there a weight limit?

Yes, for rider, bike and luggage together: 130 kg (287 lb) for Nano Road, Nano CS Road and Nano Gravel 45, 115 kg (254 lb) for Nano XC and 100 kg (220 lb) for the Yokto wheelsets. TUNE tests its prototypes on a drum under exaggerated load, so the stated limits carry a real safety factor.

Where are TUNE wheels made, and what is the warranty?

TUNE machines its hubs and builds every wheel by hand in Buggingen, in Germany's Black Forest. TUNE hubs and the Nano Road and Nano CS wheels carry a 10-year warranty for the original owner, and the TUNE Crash Replacement Program discounts a replacement after a crash: 50% within 24 months, 25% from 2 to 5 years and 15% after that.
