Our way to quality wheels

For many, a wheel is just round and must rotate. From our experience as a manufacturer of millions of wheels of various types and requirements over the past decades, we know that quality begins with the selection of the appropriate individual components. The knowledge of our own strengths and possibilities creates a range of work that our partners appreciate.

Component selection

A wheel to be manufactured consists of many different parts: 

Rim tape

Tires

Tube

Spoke

Nipple

Rim

With regard to the qualitative demands of wheel construction, we look to a wide range of selected suppliers,
with which we have been working together in part for decades:

Choice of the necessary work steps 

Based on the requirements for the use of the wheel, a technical and practical prototype is built in each case. As a result, an implementation plan is created from various work steps and the assigned machine options or determination of the manual work portion.  

The following steps are available for selection: 

After the spoke lengths are determined, we connect (mostly by hand) the hub or motor hub to the spokes. This can take different forms according to the general requirements of the finished spoke wheel or the specifications of the hub manufacturer:
  • Alternating,
  • One-sided inside,
  • One-sided outside.

It is important for us to check the correct fit of spoke head in the assigned spoke hole of the hub as well as the matching spoke angle to the flange width.

We achieve the marriage of the complete wheel by connecting the spokes to the nipples with the inclusion of the rim. Based on the requirements of the final product in terms of stability, dead weight, payload, etc., we use various lacing options such as multiple crossed, underlaid or radial. In any case, we deliberately avoid spoke crossing over the valve hole. If hubs and rims are labelled, we make sure that they are aligned uniformly for optical reasons. To minimize potential assembly marks, especially on nipples, double square, hexagonal or squorx nipples can be used under various conditions.

Considering all necessary tolerances on radial runout, lateral runout, spoke tension and centricity, the gradual and programmed adjustment of a uniform spoke tension of all spokes is carried out. In doing so, we analyse that on the respective higher pretensioned wheel sides (drive side, etc.) up to the component-dependent predetermined potential maximum of the tensile forces is applied. The background to this is that when the tires are mounted later, as well as under normal use due to the tire or external pressure, the total tension in the system decreases again.

In the course of a constant centring process, the partial loading of individual spokes (pairs) allows the components to settle at the respective joints and the specified stress values are not achieved only by higher friction of the individual parts against each other.

In order to additionally increase the quality of the wheel for special loads, simultaneous loading of all spokes on one side of the wheel can (unlike stabilizing) lead to a complete minimization of tension changes. The reason for this is the simultaneous higher pre-tensioning of these spokes. This is always associated with manual fine centring in the subsequent step.

After rechecking the centricity, we again manually increase the spoke tension that was reduced in connection with the bead breaking and adjust it over the entire wheel side. In this way, this manual processing enables us to exclude twisting of the spokes. Subsequent fine centring ensures that the highest possible compromise between concentricity and even tension distribution is achieved.

With the aim of additionally increasing the strength and longevity, especially of more heavily loaded spoke wheels, subsequent loosening of the nipple/spoke connection is ruled out by means of gluing.

By means of compressed air as well as cleaning with microfiber cloths, we remove assembly residues (which have been created, for example, by punching and drilling the rim holes) and oil deposits, so that no additional noise is created during use or dirt is bound, which can lead to damage.

According to the model selection we mount rim tape, bicycle tube as well as tire. In doing so, we pay attention to a clean fit of the tire and align possible logos to match the valve position from an optical point of view.

From the (customer's) desire to deliver a finished wheel, we assemble gear components, brake accessories or other mounting materials according to customer or supplier specifications.

For customer use as an indicator in the production process or for posting reasons within the respective ERP- system, we label spoke wheels individually according to customer request.

We ensure a consistent quality standard according to the agreed specifications by digitally integrating all measurements and controls in the customer order - production order - delivery bill - invoice process. As a result, a high degree of sustainability is achieved and subsequent inquiries or adjustments can be processed in a provable manner.

In addition to checking measurable specifications, we also aim to exclude possible production marks or defects in the starting material by checking the overall visual impression of the spoke wheel.

Based on the logistical requirements and possibilities, we pack and ship in the following options

  • wheels packed individually in a cardboard box
  • wheels packed in pairs in a carton
  • wheels packed in carton (4 pcs.)
  • wheels packed in carton (10 pcs.)
  • wheels packed in EURO box pallet (exchange system)
  • wheels packed in wheel rack (for pickup and return in direct transport)

To minimize shipping effort and costs, we optionally bundle possible partial deliveries and create a timely delivery in digital exchange.

Machine production is good - sometimes only manual labor helps

When is "good" really good? - or - the definition of (manufacturing) tolerances 

A well-spoked and centered wheel is characterized by smooth running. Depending on the intended use of the respective wheel, the requirements are not the same in every case:  

  • A running wheel for strollers regularly reaches lower speeds, 
  • The use of wheels in cargo vehicles entails special requirements with regard to stability, 
  • Sporty wheels for use in triathlon bikes require high torsional and lateral stiffness despite low weight, 
  • …, the list could be extended infinitely. 

Thus, details and associated tolerances are defined in coordination with customer expectations: 

Spoke length

Spoke crossings

Spoke tension

Late runout

Altitude shock

Centricity

Offset

Tested quality 

With the aim of meeting our standards and customer requirements, each project begins with an article summary in the document management system. By means of an article master file, the basic conditions for components and production are defined and then refined and checked in the prototyping process. Thus, the qualitative journey already starts at the goods receipt of new products by carrying out an initial inspection. While the individual parts are assembled into wheels in the respective work steps, the wheels are tested for target achievement at the end of production according to specified proportions: 

  • Are there any material damages or optical defects due to the machine production? 
  • Were all tolerances observed? 
  • Is the spoke pattern correct? 

A digital test report underlies every production order and ensures the standard.  

Packaging 

True to the motto "...a product is only as good as it is received by the customer...", we fulfill various requirements of our customers and at the same time try to proceed in a resource-saving way. Possible is

  • Wheels individually packed in cardboard box, 
  • Wheels packed in pairs in cardboard box, 
  • Wheelspacked in carton (4 pcs.), 
  • IWheels packed in carton (10 pcs.), 
  • Wheels packed in EURO box pallet (exchange system), 
  • Wheelsto be shipped packed in wheel rack (for pickup and return direct shipping). 

In this process, all deliveries are protected separately by using reusable materials for padding.  

Supporting the storage process of our partners, we offer customer-specific labels which enable the automatic scanning and booking of the goods. This can be done by means of a cardboard label or a spoke label directly on the wheel.
