Rims

Processus de frabrication

**Step 0: Profile**

Reception of raw materials in the form of aluminium bars. Each profile corresponds to a specific rim according to its internal shape, finish and final diameter.

**Step 1: Bending**

The aluminium bars are bent to form 2 to 4 turns, with specific tooling for each rim.

**Step 2: Sawing**

The resulting coils are sawn to form open rims, which gives the final diameter of the rim

**Step 3: Sleeving**

The rim is closed by pressure with a sleeve or two pins

**Step 4: Drilling**

The spoke and valve holes are drilled automatically on the rim, according to the required parameters: number, diameter and positioning.

**Step 5: Eyelets** (optional)

Installation of the eyelets at the spoke holes, single or double eyelets.

**Step 6: Machining** (optional)

The rim is machined to create the brake pad planes.

**Step 7: Stickering, Printing, Engraving**

The rim is cleaned and a customisation can be made. The operator carries out a final visual check of the quality of the product.

Spokes

Manufacturing process

From 120 to 210 spokes produced per minute!

The manufacture of spokes is a largely automated, high-speed industrial process. Various mechanical operations punctuate the transformation of the wire, which is delivered in reels: cutting, cold heading to form and then bend the head, and finally threading. The choice of materials - steel or stainless steel - and the shape – for example a narrower diameter in the centre - determine the strength and durability of the spokes.
