Optimised V-shape

Optimum force transmission from the spokes via the nipples to the rim, slightly angled flanks for improved aerodynamics, reduced hook area for optimum tyre to rim contact – the rim performs at its best with 28 mm wide tyres. The specially optimised shape reduces susceptibility to crosswinds and gusts, making the rim the first choice for a smooth ride in diffuse conditions.

Rim width

21 mm – We have extracted the maximum rim width from the shape without removing the safety aspect of a hook. The rim is wide enough to offer a lot of fun even on rough surfaces. The width also makes the rim a suitable choice for modern frame models.

Rim construction

The rim consists of high-quality Japanese fibres that are laid down in a near-netshape in the preforming process to suit the load. At every point of the rim, the fibres have the same optimum angle to the centre of the wheel – this uniqueness allows us to reduce weight and achieve thin wall thicknesses without sacrificing stability and impact resistance.
In an iterative process, the fibre architecture was examined in detail and successively optimised by a team led by Stefan Schmolke. Once the optimisation of the fibre design was complete, the fibre volume content, i.e. the ratio of fibres to resin, was readjusted. Model considerations were transferred into countless prototypes and the tools and moulds were optimised step by step. The rim has been successively optimised and improved since 2017 – for example, improvements were made to the layup of the impact area and improved rim bed dimensions.
The impact-reducing fleece on the horn is made from 100% recycled fibres.

Hubs of our trust

Extralite – right from the start, we have been using the ultra-light hubs from Extralite, which are CNC-milled from high-strength 7075TX aluminium near Milan. The hub body rotates around a 15 mm front and 17 mm rear aluminium axle with HDC ceramic deep groove ball bearings. The axial play can be finely adjusted using the micro-tuner. A tried and tested pawl freewheel works in the rear hub. A new feature is the use of titanium gearing with 32 teeth, which is controlled by two pawls.

Spokes

We use steel spokes from the Belgian manufacturer SAPIM on all of our wheels. With the CX-Ray elliptic spoke we installed, Sapim has succeeded in developing an exceptional spoke. In addition to its low weight, it has exceptional load capacity and flexibility. This also results in the large area of ​​application. Regardless of whether it is a racing bike, gravel or MTB wheelset, they all benefit from these positive properties. In addition, the flattened middle section ensures excellent aerodynamics. The high quality of the material enables the construction of stable wheels and guarantees a long service life.

Which freewheel system do I need?

Before you make the purchase, you should be clear about which group set you have installed on your bike. This determines which freehub body you should order.

Shimano – if you have installed a Shimano group set, please select Shimano (HG-11) as the freehub body. Even with the new 12-speed group, the cassette can still be installed on the conventional HG-11 freehub body without any problems.

SRAM – if your bike has a SRAM group with an 11-speed cassette, you should choose the Shimano HG-11 freewheel body to be able to install your cassette. The newer 12-speed AXS gears from SRAM require the XDR freehub body for assembly, in which the cassette is screwed onto the body in one piece.

Campagnolo – if you have installed a Campagnolo 12-speed group, we ask you to select the “Campagnolo” freehub body when ordering. For example, if you need the N3W freehub body for your “EKAR” gravel group, please let us know in the order comments.

Wheel building

The TLO30 wheels are painstakingly laced and centered by our wheel builder. This is done in our workshop in Konstanz on beautiful Lake Constance. Great care is taken to ensure that each wheel is finished with optimal concentricity and the correct spoke tension. In order to optimize the fit of the spokes, our TLO30 wheels are machine pressed several times with a precisely defined force. This means that you as a customer do not have to have the wheels re-centered after a short time, but can enjoy the full driving pleasure of the wheels straight away and without any restrictions.
